A hacksaw is a must-have tool in almost any home. Sawing various parts wood or processed garden trees- this is a common thing, so it is quite difficult to do without a special tool. To choose a good and high-quality product, first of all, you need to figure out how to choose the right hacksaw for wood. This tool has a lot of varieties that differ in some details and build quality.
Despite the simplicity of the hacksaw device for wood materials, in the matter of their choice, you need to be savvy and have the necessary knowledge. Otherwise, there is a possibility of acquiring an inconvenient or not quality tool. In addition, it should be remembered that hacksaws can be sold unsharpened. In other words, you won't be able to get to work immediately after purchase. Below we discuss how to choose a hacksaw for sawing wood materials with a description of all the nuances that you should pay attention to when choosing products.
Basic characteristics of the tool
First of all, it is worth looking closely at the tool, focusing on its main part - the canvas. From the quality of the metal, its production and correct sharpening comfort during operation and durability of the device depend. When choosing a quality product, you need to focus on 4 main factors:
- canvas size;
- tooth size;
- type of metal;
- pen shape.
Of paramount importance is the size of the canvas. Its length is selected based on the purpose of the application. For narrow rails, wooden skirting boards and boards, a saw is suitable, the length of which is from 25 to 30 cm. If you decide to build any building yourself, it is advisable to choose a hacksaw from 45 to 50 cm.
The main criterion for choosing the length of the canvas is the diameter of the tree to be processed. The size of the hacksaw should exceed it at least 2 times. You can purchase a tool of a slightly shorter length, but this may cause problems during operation. The main difficulty will create a jamming of the blade inside the wood, since the teeth will not be released during the cut to drop the sawdust. The second reason is the lack of comfort. In other words, you will spend much more physical strength for sawing, because the muscles will tighten more from sweeping body movements.
The size of the teeth and their sharpness affect the performance and accuracy of sawing. When choosing a tool, you need to take into account that the smaller teeth are designed for high-precision sawing, but they have some performance limitations. With large teeth, sawing is not as accurate in favor of high-speed work, that is, you will spend less energy on sawing.
This property is marked on the tools as TPI (total number of teeth per 1 inch). The accuracy of sawing depends on the value of this indicator. For example, when working with boards such as chipboard / fiberboard, you should use a hacksaw with a TPI of 7-9. This will allow you to cut the material neatly without crushing its surface.
If the tool is purchased for sawing trees, then there are no requirements for the accuracy of the work. In this case, the main criterion is the performance of the tool, so the most suitable option there will be a saw with a TPI from 3 to 6, where the interval between the teeth is 4-8 mm.
Preparing a hacksaw for work: a - tooth setting; b - sharpening.
Standard teeth on hacksaw blades are triangular in shape. Most of these teeth can be sharpened from time to time. Modern Instruments have trapezoid teeth. In the process of their production, the slope is made for high strength and wear resistance. Such a saw cannot be sharpened, since it is quite difficult to give the teeth the necessary shape during processing. In addition, the high-strength metal from which they are made is difficult to grind. Therefore, after the end of the service life of the hacksaw, you will have to buy new tool Or change the canvas.
The metal used for saws also has its own value. The classic hardness of steel for sawing trees is 45 HRC. For teeth, metal with a hardness of 55 to 60 HRC is used. Such tools simultaneously combine wear-resistant teeth and flexible base. Hacksaws with inherent characteristics are easily identified visually because the blade has a lighter shade in relation to the teeth. Most of these saws cannot be sharpened. The only exceptions are models with teeth that have not been hardened.
Last but not least, attention should be paid to the handle, since only the convenience of using the tool depends on it. Handles are either flip or standard. In the first case, it is possible to replace the worn blade.

How to choose the right wood saw?
First you need to figure out for what purposes the hacksaw will be used: in carpentry or carpentry. In the first case, the tool produces high-precision sawing and is used for dry wood. The speed of work in carpentry not as important as accuracy.
The length of the blade is selected based on the purpose of use, that is, the size of the wood for sawing. For passive use, it is better to choose a hacksaw with hardened teeth, as it will often be idle. Thanks to long term service of such saws, you will not need to sharpen them, which in itself is a laborious process.
The quality of the product is easily determined in the process of its acquisition.
You need to take a tool and first of all evaluate the uniformity of the canvas. After that, it is necessary to bend it by about 30-45 ° and release it. Do this carefully, as low-quality material can be broken. Then evaluate the uniformity again. If a slight deviation appears at the bend point, the metal of the product is of poor quality.
Tool teeth have 2 tasks:
- sawing a tree;
- remove sawdust.
If the arrangement of the teeth on the blade is rare, the productivity of the tool increases, and the sawdust does not clog the processing site. Saws with a TPI rating of up to 7 are considered high-speed and comfortable to use. However, their disadvantage is the low accuracy of sawing.
Therefore, you need to focus on your own needs and look for a ratio of indicators that suits you. The optimal option for all types of work is selected as follows: the minimum diameter of the processed wood must be larger than the segment in which 3 teeth are located. Otherwise, it will complicate the sawing process, and you will quickly get tired.
Sawing tools can cut both lengthwise and across. The teeth of a saw designed for cutting along have a slight slope. She cuts the wood with a movement away from herself. The size of a standard tool is no more than 50 cm, the angle of the teeth is always sharp. Crosscut saws are much more common, they can be found in any construction stores in a wide range. Their teeth are sharpened in both planes. This allows you to cut wood in and out.
When choosing a tool for sawing wood, its cost is important. A standard pattern applies here: expensive and branded models are of high quality, unlike fakes from China. If you need a hacksaw for a one-time job, buying a branded model is not necessary. But for long-term operation, it is recommended to look at quality hardened steel products.
As a rule, good products are made from high quality steel, which is processed using advanced technological solutions. It takes into account many little things, ranging from the shape of the teeth and ending with the interval between them.
Hacksaws for wood differ in the size of the cutting teeth. This parameter determines how the cut will turn out, what types of wood the hacksaw is suitable for and how easy it will be to work with it. But besides this, there are other characteristics that you should pay attention to when buying a tool. Therefore, the question of how to choose a hacksaw for wood is relevant and requires a thorough approach.
For a hacksaw on a tree, the following matters:
- canvas length,
- canvas width,
- canvas steel grade,
- lever,
- tooth size.
The length of the blade affects not only the width of the cut wooden workpiece, but also greatly simplifies the work. The long stroke allows you to make less effort, since in one movement the cut is carried out by a large number of teeth. On the other hand, the longer the canvas, the more it springs. When dealing with hard woods such as oak, maple or ash, the saw will cause a lot of inconvenience and will quickly become dull.
On the practical side, short hacksaws, with a long cutting edge up to 30 cm, are more appropriate to use for small one-time work. They are suitable for those who live in an apartment, as they do not take up much space. Accordingly, in a private household, it is better to immediately buy a long saw (45-50 cm). This will allow you to work not only with blanks, but also to cut trees.
Usually the width of the canvas is from 10 to 20 cm. Narrower options are not allowed for technical reasons (they will break at the slightest bend), wider ones are too inconvenient for self made. When choosing a hacksaw for wood, it should be remembered that thin workpieces are easier to cut with a narrower blade, and thick ones (tree trunk, roof logs, etc.) - with a wide one.
For hacksaws, alloyed tool steel grades are used:
- U8GA,
- 60C2A.
All of them are certified by GOST and differ high content carbon (0.7 - 0.8%) and silicon (0.1 - 0.4%), which makes the steel strong and resistant to fracture. Other steel grades do not meet the technological requirements for the product.
Conventional handles are made of plastic. It is advisable to choose a handle with a rubberized backing for the fingers. This will allow you to make a tighter grip and protect your hand from calluses.
The teeth of the saw are the most important part of the tool, so it is worth dwelling on them in more detail.
Varieties and purpose of teeth
The following types of teeth are distinguished:
- for longitudinal cutting
- for cross cutting
- for universal cutting.
Longitudinal cutting is usually carried out either circular saw(round saw blades), or with a jigsaw. But there are also hand saws for these purposes. As is the case with electric counterparts, the teeth on the saw resemble hooks. The angle between them is allowed 40-55 degrees.
The hook shape allows cutting in only one direction. It is preferable to cut along the fibers. Then the hacksaw easily penetrates through the tree and the cut is obtained as even and accurate as possible. The choice of such a hacksaw is appropriate only for those who have a desire to make furniture on their own. Since it is not suitable for any other purpose.
Tooth for cross cutting is the most common. Outwardly, it looks like an isosceles triangle. The angle between the teeth is 40-50 degrees. This design allows you to cut equally well both when moving the cutting edge forward and backward. As a result, cross-cutting is carried out as accurately as possible, quickly and without much effort. When buying a hacksaw, it is important to consider that this type of tooth is only suitable for dry workpieces. The saw will tear fresh wood, and the sharpening will deteriorate.
For fresh branches, triangular teeth with parallel sharpening are used. This means that each tooth is sharpened in a checkerboard pattern and only on one side. As a result, a free channel is formed between the teeth inside the cut, through which wet sawdust can freely exit the cut without hindering the movement of the saw.
Another option is the combined composition of the teeth. It combines triangular with semicircular. At the same time, semicircular elongated teeth are longer than triangular ones. When the hand moves forward, narrow long teeth make a guide cut, and when the hand returns to its original position, the triangular tooth expands the cut channel and removes sawdust and chips from it.
It should be remembered that the smaller the angle between the semicircular and triangular teeth, the more accurate the cut will be.
It is better not to buy hacksaws for universal cutting, they are usually equipped with various tooth compilations, which in theory should do the job equally well. But in practice, such saws become dull much faster, and their sharpening often costs more than a new hacksaw.
And most importantly - in any high-quality hacksaw, the teeth are always made of hardened metal.
Types of hand saws for wood
There are several types of hacksaws, including:
- narrow
- regular,
- with collar,
- beam.
A hacksaw for wood, the price of which is the lowest is narrow hand saw. This option is suitable for gardening, sawing branches and small work with wooden blanks. Usually, either parallel tooth grinding or triangular double-sided teeth are used.
It is important to understand that it is possible to work with such a saw only with workpieces whose thickness does not exceed 8-10 cm. Too short a blade does not allow you to create a lever, therefore, sawing thicker parts will require a lot of physical exertion.
Conventional hacksaws are made with any type of teeth. The choice depends solely on the purpose for which you plan to buy a tool. Attention should be paid only to the fact that it is extremely undesirable to work with such hacksaws in the manufacture of furniture. Or you should buy special miter boxes to be able to saw off at a certain angle.
Hand saws with a butt are used as an additional tool. Their main task is not deep cuts in the workpiece.
Bow saws are an analogue of an electric jigsaw. They allow you to make the most accurate cut and work with any workpiece at any angle. Allocate:
- swing,
- transverse,
- circle,
- spiked.
Sweep saws allow you to make rip cuts. On the market there are canvases from 40 to 80 cm in length. Longer workpieces can only be sawn with an electric tool.
Crosscut saws are designed for sawing workpieces across the wood fiber. They make a cut both at right angles and at any other. In this case, perfectly smooth edges are obtained at the place of the cut.
Circular saws are narrower and are used for shaped sawing. With their help, make rounding and others complex elements. A distinctive feature is the use of particularly flexible metal grades.
Tenon saws allow you to make simple geometric figures on the workpiece.
A feature of bow saws is that the fastening mechanism is made or bought once, and the saws themselves are not sharpened, but new ones are purchased (as for hacksaws).
Recommended Hand Saw Manufacturers
Professional hacksaws for wood are distinguished by quality and compliance with the declared parameters. Buying goods from trusted manufacturers, you will be sure that the tool will last a long time and reliably. Among the verified firms, it is worth highlighting:
- bahco,
- Stanley,
- Gross,
- Sandvik.
Bahco is a Swedish company that is part of the SNA Europe Corporation. For more than 200 years of history, the manufacturer has never changed the main concept - the production of affordable quality hand tool. Bahco hacksaws are distinguished by durability, and a pleasant price from 500 rubles.
Sandvik wood saws are sometimes found on the market. This company is part of Bahco, so the quality of the products corresponds general requirements concern.
The American manufacturer of hacksaws for wood, Stanley, also emphasizes the availability of its products. The company is distinguished by an extensive staff of designers and engineers. Thanks to their work, the hacksaw blade and cutting edge differ from the Russian GOST, but this does not affect the quality in any way. This company is ideal for those who buy a hacksaw for the country. Since the combined teeth allow you to carry out any kind of cut. Price from 400 rubles.
The German company Gross is younger than its opponents. The competitiveness of its products is achieved due to very low prices (from 250 rubles). Nevertheless, the products are of sufficient quality and comply with all domestic technical standards. The only downside is that the range of products is quite small.
There are also domestic manufacturers who offer relatively inexpensive and quality options. Among them:
- bison,
- Piranha.
The Bison hacksaws are made in China, but meet the requirements for steel and teeth. Of the minuses:
- should not be left outside (it rusts quickly, even with slight humidity),
- time of continuous work no more than 10 minutes (rest 15 minutes),
- not suitable for working with hard woods.
Despite this, these hacksaws will come in time for cutting garden trees.
The Piranha company is relatively small and has not been operating for a long time. Like everything new, its products are very affordable (up to 500 rubles) and are of high quality. Piranha hacksaws are presented in just a few models. The country of origin is China. But, unlike the Bison, the products of this company are covered with protective Teflon, which protects the tool from corrosion, even if you forget it in the rain.
During my work, I often have to cut various wooden elements. And, if it is not possible to use a power tool, a wood saw comes to the rescue. I will tell you how to choose a quality tool, and point out what to look for when buying. And as a bonus, I will list a few specific options that worked best.
Tool Selection Criteria
The main characteristics of any hacksaw are:
- The length and width of the canvas;
- The type of steel from which the canvas is made;
- The size and configuration of the teeth;
- Construction type.
Let's take a closer look at each aspect.
The length and width of the canvas
Regarding these aspects, you need to know the following:
| Illustration | Description |
 |
Short hacksaws are used for cutting small elements.. The length of the working canvas in them is no more than 30 cm. With this version of the tool, it is very convenient to cut thin bars and sheet materials such as plywood, fiberboard and chipboard. The tool can be different types This aspect is described in more detail below. |
 |
Medium options are suitable for any work. The most popular type of tool has a blade length of 35-50 cm. Using such a hacksaw, you can cut any boards and bars. |
 |
Hacksaws over 500 mm long. This option is mainly used for ripping thick elements. They are not common, as sawing large bars or logs by hand is very difficult. |
 |
Canvas width up to 50 mm. These are the so-called narrow hacksaws used for cutting small elements and sheet materials of small thickness. |
 |
Hacksaws with a blade width of 100-200 mm. Most often, the canvas tapers towards the end, that is, the width changes from the handle to the end of the canvas. This configuration simplifies sawing and reduces the chance of blade getting stuck in the tree. There are also options with the same width of the canvas along the entire length. Most often, these are bow and back type saws (their features are described below). |
The wider the canvas, the stiffer it is, but the likelihood of the working part getting stuck in a thick piece of wood is higher.
As for the length, it should be approximately twice the thickness of the elements being cut. This ratio allows you to work sweepingly, and the hand will be much less tired. The instructions on the packaging will tell you exactly what kind of work this or that model is intended for.
The fabric material
It is difficult to determine this aspect by eye, so the package must contain all the information:
- steel grade. Most often, one of the following options is used in the manufacture: U7, U7A, U8, U8A, U8G, U8GA, U9A, U10, 8HF, 9HF, 9HS, 65G, 60 C2A. These are all grades of alloy steel with high hardness and good wear resistance;
- Steel hardness. The minimum value that a hacksaw must meet is 45 HRC, but it is better to choose options with a hardness of 50 to 60 HRC. The marking is either on the package or on the hacksaw blade itself, the photo below shows a variant with a hardness of 55 HRC;
- hardening. For strength, the teeth of the hacksaw blade can be hardened. In this case, they acquire special strength and wear resistance. But hardened teeth cannot be sharpened, so after the blade wears out, you need to buy a new tool. Non-hardened options wear out faster, but they can be undermined as needed with a special file.
If you use a hacksaw only occasionally, then it is better to purchase a hardened version. With infrequent use, it will last at least a few years. At active use it is better to take a non-hardened hacksaw and sharpen it as needed.
Tooth size and configuration
Understanding how to choose a hacksaw for wood, Special attention given to the teeth. The quality of work and its productivity depend on them.
Tooth pitch is defined as TPI, which is an abbreviation for the number of teeth per 1 inch (25 mm). All products have the appropriate marking, so it will not be difficult to figure it out:
- large tooth. This is 3-6 TPI. These options provide the best performance. The hacksaw cuts very quickly, but at the same time it damages the ends and the sawing quality is not very high. This option is suitable for work in which speed is important;
- Middle tooth- 7-9 TPI. Universal option tool for good cutting quality average speed work. It is this option that you need to purchase if you will be sawing different materials;
- small tooth- from 10 TPI and above. Such hacksaws are used where the highest value is given to quality. The ends are neat, without burrs and scuffs, but the speed of work is several times lower than when cutting with a hacksaw with a large tooth.
It is very important to choose the right type of tooth. This directly affects specifications wood saws:
| Illustration | Description |
 |
Rip saws. Used to cut wood along the grain and have a bent tooth. This configuration only cuts in one direction, when the tool moves in the other direction, the sawdust is removed from the cut. |
 |
Hacksaws for cross cutting. Used to cut material across the grain. They have even triangular teeth with sharpening on both sides, which allows you to cut elements in two directions. |
 |
Universal hacksaws. They have a trapezoidal beveled tooth of a special configuration. With its help, both longitudinal and transverse cutting are carried out equally well. |
 |
Special Options. A modern professional hacksaw may have unusual option teeth, which are divided into separate blocks. This type of tool is designed for cutting raw wood, thanks to the gaps, the sawdust is removed very efficiently.
|
Types of hacksaws and the most popular options
All products can be divided into 4 groups:
- Narrow hacksaws. They have a small web width and are designed for curly cutting sheet materials and sawing of small elements;
- Bow saws. Represent a frame with a stretched canvas. Used when cutting elements of large diameter;
- Hacksaws. They have a stiffening rib in the upper part, so that the canvas does not bend during operation. With this tool, you can make perfectly even cuts with your own hands;
- Standard Options. The most popular and widespread type of hacksaws. Differs in universality, convenience of application and compactness.
Now I will give a couple of examples. The hacksaws listed below have been personally tested and perform well:
- Stanley General Purpose. Very a good option with an average tooth size (8 TPI). Cuts easily and fast enough, suitable for both wood and sheet materials based on it. Hardened edge ensures durability. The price is approximately 800 rubles (prices are valid for the spring of 2017);
- Gross Piranha. An excellent tool that is produced in different options length and with different size teeth. Hardened steel with high strength is very durable, and the Teflon coating of the metal ensures easy running when sawing. This option costs about 1000 rubles.
Conclusion
Now you know exactly what kind of wood saw you need in your case. I recommend watching the video in this article, and if you have any questions, ask in the comments.
Hacksaw, which one is better, this is the question asked by all those who need to work good tool.
Kinds
In addition to expensive models, you can find a hacksaw for wood and a simpler one, but it will be an ordinary hand tool.
The simplest tool is well suited for small-scale work, but if you constantly have to cut something, it is better to take care of purchasing an upgraded version of the tool.
There are several types of wood saws, and they are divided into groups depending on the type of teeth.
The first group includes hacksaws for longitudinal sawing. They are designed to cut material along its fibers. In this group of instruments, the teeth are made in the form of an oblique triangle.
The second group includes hacksaws designed for cross cutting. Their tooth shape is different from that of rip saws. Here we will see teeth in the form of an isosceles triangle.
The third group of hacksaws is more versatile and allows you to cut material in almost any direction. These hacksaws have teeth in the shape of a right triangle.
In addition to the shape of the teeth, when buying, you need to pay attention to the quality of the hacksaw blade.
Note: when examining a tool, one should not forget that it hits the counter already sharpened, so it must be handled very carefully.
The service life of a hacksaw will depend on the quality of the metal used in its manufacture, so it is also necessary to pay attention to this nuance. The inconvenient shape of the handle can greatly complicate the work with the tool, so it also needs to be paid attention.
Criterias of choice
Inspection of the selected tool must be carried out in the following order:
1. First, a knife blade is selected, and first of all, it is necessary to pay attention to its length. The types of work that can be performed with this tool depend on this.
2. The next selection criterion is the shape and size of the teeth.
3.Handle shape.
As for the canvas, for small household chores, a canvas with a length of up to 30 cm is enough. For construction works- up to 50 centimeters.
The most popular and, accordingly, sold are the following models:
- Stanley Jet Cut Its average cost is 1300 rubles.
- Zubr Expert. Price -700 rubles
- Stanley General Purpose. The cost is 700 rubles.
- BAHCO Laplander 396-LAP. One of the most expensive hacksaws. Its price is 2000 rubles.
For example, the Stanley Jet Cut hacksaw has a very comfortable handle and a 50 cm long blade. It is made of high quality steel. It can be effectively used for most types of work, so the price of 1300 rubles is fully justified.
The same can be said about the other listed models. All of them are by far the best examples that can be found on the construction market. You can verify this if you read the reviews of people who already work with this tool.
Suppose we need to fit a wooden baseboard or trim the garden. It would seem that we take a hacksaw and saw. What kind of wood saw do you use? No, the question is not at all idle. In order to be convinced of this, it is enough to go to any building supermarket or an online store that sells tools. Dozens of models are presented to our attention. And they differ not only in logos and price.
It seems to be a simple tool, but no, with the wrong choice, at best, we will not get the expected pleasure from work. At worst, since the author of the comment on the forum: “It seemed to me that saws were sold ready for use, i.e. already imprisoned and divorced. So how to choose a hacksaw for wood? What to look for: brand, length or price? We will try to answer this question in this article.
Main characteristics
The canvas is of paramount importance in this tool. The ease of use of the product and its service life will depend on the steel grade, the correct hardening procedure and successful sharpening. The choice of a hacksaw for wood is based on four basic characteristics:
- canvas length;
- tooth size;
- steel type;
- handle type.
The first criterion is the length of the canvas. It depends on the needs of the buyer, so for small bars, boards, etc. a 280 - 300 mm hacksaw is enough. For construction or summer cottages, a canvas of 450 - 500 mm is more appropriate. There are more. When choosing a model, you must clearly know what size wood you are going to cut. The rule is as follows: the length of the hacksaw should be twice the largest workpiece for which it is intended. You can do less, but the usability will be lost. This is due to several reasons:
- this ratio allows all the teeth of the hacksaw to completely exit the log during the cut, and this effective removal sawdust (will not clog);
- it is easier for the hands, with more sweeping movements, the hand does not get so tired.
Teeth size and sharpening. From this characteristic will depend on the accuracy of the cut and its speed. The rule is this: small tooth- clean and precise cut, but less speed; larger - a rough cut with significantly higher speed and less fatigue. This characteristic on hacksaws is referred to as "TPI", which means the number of teeth per inch (almost 30 mm). The larger the TPI value, the more “delicate” the cut will be. For example, for work with chipboard and fiberboard, this value should be at least 7 - 9. The cut surface will be smoother without a “torn” edge.
For garden work, the cleanliness of the cut is not so critical, especially for trimming or sawing logs. A more important characteristic in such work is the speed of sawing and the effort to be expended. To do this, we need a hacksaw with a TPI value of 3-6, the distance between the teeth is from 4 to 8 mm.
The classic shape of a tooth is a triangle. As a rule, such saws are of the sharpened type. The latest generation of hacksaws with hardened teeth are trapezoidal in shape. They are initially designed with increased strength and wear resistance. When it gets dull, we go, buy a new hacksaw or change the blade. With all the desire to sharpen it will not work: it is extremely difficult to repeat the sharpening angles, and even such steel cannot be filed. Provided that the production technology is observed.
Steel type. The standard metal hardness for a wood saw is 45 HRC. For teeth, steel with a hardness of 55 - 60 HRC is used. This type of hacksaw combines the flexibility of the blade with high wear resistance of the teeth. They are easily recognizable by their characteristic appearance- the teeth have a darker shade than the rest of the blade surface. These hacksaws are of the non-sharpened type. If the teeth are not hardened, they can be straightened and sharpened.
Lever. The number of calluses on the hands depends on its ergonomics. There are two options for the handle: flip or classic. The first option allows you to change blades, for example, in the Bahco Superior EX-19-XT9-C hacksaw model.
How to choose?
First of all, it is necessary to determine what type of tool is needed: carpentry or carpentry. The carpentry has a more accurate and clean cut, it is used mainly for dry wood. The cutting speed for this type of tool is not the main characteristic.
When choosing a length, be guided by your needs, i.e. what size timber or log are you going to cut. If the tool will be used infrequently, for example, on suburban area, choose with hardened teeth. The resource of operation of such a saw is large. In addition, correctly sharpening and setting teeth is its own science, and mastering it for seasonal work in the garden may not be appropriate.
The quality of the canvas can be checked upon purchase. To do this, take a hacksaw and see how smooth the canvas is. Next, bend the canvas to tangible resistance and release. The zeal of the fold should be slight, do not break. After that, look at the evenness of the blade at the bend, if the deviation is more than 2 mm - the steel is not of very high quality.
The teeth of a hacksaw have a dual role:
- cut wood;
- remove sawdust.
The fewer teeth per inch, the better more speed cut and less clogged with sawdust. Hacksaws with up to 7 teeth provide high performance with little user effort. True, accuracy will suffer from this. But even here it is necessary to look for a golden mean, because. the greater the distance between the teeth, the smaller the cutting surface. As a result, performance will drop. The best option will next rule: the minimum thickness of the bar must be greater than the pitch of three teeth. Otherwise, it will be flour, not cut.
Hacksaws can be with a longitudinal and transverse cutting method. Longitudinal blades are easy to recognize by the angle of inclination of the teeth; such saws cut only from themselves. Usually their length does not exceed 50 cm, they have sharp corner cut - 75 - 800. Most of the presented models in stores can be attributed to hacksaws with a cross cut. They have sharpening on both sides of the tooth. That allows you to cut both when moving forward and backward.
One of the determining criteria for choosing a hacksaw for wood is the price. As with everything else, quality products from leading brands will cost more than Chinese brands. This overpayment, in fact, is a guarantee of durability and wear resistance of such a tool. And with hardened teeth, this is very important, the overall service life of such a tool will depend on this. It does not lend itself to sharpening. Leading manufacturers exercise tighter control over the choice of steel grade and hardening technology. And as we discussed above, even the shape and pitch of the teeth of such a tool will affect a lot. Starting with the convenience and effort expended, ending with the accuracy and evenness of the cut.
Models to look out for
The models below are highly good feedback both according to the results of specialized tests of the tool, and according to the opinion of the users themselves. For convenience, all models will go according to an increasing price category, from budget to professional wood saws.
Hacksaw for wood Zubr Expert It has a very comfortable plastic handle. The teeth are hardened, triangular in shape with two cutting edges. Suitable for both longitudinal and transverse sawing. The length of the blade, as well as the number of teeth per inch, the user selects independently, the variations of this model are different. It cuts well on any type of wood. This tool is suitable for carpentry work, because. controllability and cutting accuracy at height. For the garden, you can choose a model with a lower TPI value. The cost is from 12 to 15 USD.
Hacksaw Gross Piranha also available in several versions. Blades Available in different lengths (from 400 to 550 mm) and different numbers of teeth.
