Greetings dear readers! It’s so nice when a person has his own hobby, I’m really happy for these people and find them interesting and fulfilling. I also like to “handicraft” something in my free time. But I rate my skills between a D and a C. You might want to cut a carved bench for a bathhouse, or a solid wood stool for a garage. It seems like a craft that no one needs, but the soul rests. For this purpose the usual carpentry tool. And when it comes to small local crafts, be it sculpture, engraving, carving, polishing. This is where a Dremel becomes indispensable. When I was offered to review the dremel that had already appeared on Muska’s pages, I agreed, because the truth does not fade from repetition. Under the cut there will be a disassembly and examples of use and attention, a lot of photos!!!
Packaging and equipment
The Dremel comes in its original packaging, which has a picture of the tool itself and some advertising information.
The main characteristics are drawn on the side of the box
The other side of the box has the same print.
On the second side there is a description of accessories.
Only the manufacturer's name is large at the top
The box contains a set of 30 different abrasive attachments.
The set is closed with a plastic transparent lid, each nozzle sits in its own place
Here's a closer look at the nozzles. Everyone will find something suitable for themselves.
The length of each nozzle is about 45 mm
The set includes a convenient attachment for vertical milling, with adjustable immersion distance into the material.
They gave us safety glasses as a gift.
And then in a bag in bulk they gave us a lot of gadgets for the home handyman.
This whole scattering
Cutting discs
Different size collets, Spare brushes

To replace the brushes, you don’t have to disassemble the Dremel; there are 2 special compartments for hot replacement; you just need to unscrew the 2 caps on the sides
Disassembly
Exploitation
In order to show the “abilities” of the Dremel, you can come up with a lot of scenarios.I have 2 cats “on the farm”, or rather a cat and a male cat, since we live in the private sector, they are left to their own devices and roam freely. If the cat is not yet particularly active, then the cat is a real CAT. It may take a week, come back thin but happy. And so that during these spree times his mistress would not add gray hair, I decided to try to make a sign for the collar, on which the nickname and our phone number would be written, if someone finds this beast when he goes crazy from hormones and cannot return home, they will call “his family.” In general, there was already an attempt at such signs, I ordered them from an advertising agency, they were made of plastic and they swore that they were of high quality...
Like these ones
But in fact, they served no more than a week and were lost and chewed to pieces.
I got very high quality strips from of stainless steel, 1mm thick. 
But the trouble is, I tried to drill a hole, and... I couldn’t do it, 5 dead drills, from different manufacturers and 0 effect. I thought that a fiasco awaited me here too. But the Dremel pleased me.
Loaded the cutting disc and let's cut :) 
I cut out a rough shape 
Improved it a little 
On the other side 
I took out the engraving attachments from the kit and began to try my hand... 
Oh, this is painstaking work...
It's obvious that it's clumsy, but this is a test sample.
It remains to drill a hole for the collar ring.
It’s impossible to do this simply with a drill, so first I removed it a little at a time with a roller cone. And then, when a tiny hole became visible, I “finished it off” with a drill. As a result, the drill was killed :)
But the result was achieved, albeit an ugly result. 
Here is the disk after all the work, it’s clear that once I freaked out and pulled sharply, a triangle broke off from the disk... in general, ghxyst disks do an excellent job with such strong stainless steel, with hardened screws, but they are fragile in this direction. 
Then I decided to “sand” the surface a little; the sanding attachment did an excellent job of this. 
Then I refined it a little with a cutter 
A lot of work was also required to carefully engrave the number on the back, but it didn’t work out to hang the craft on the cat, he hasn’t been home for half a week...
After such work, here is the condition of the cutting disc.
was 
It became 
Then I made a small table out of plywood. But there were no suitable screws; they were slightly longer than the thickness of the plywood. I was too lazy to go to the store; the table was not for the exhibition, but to help myself. 
In the end it looked like this 
there is nothing pleasant here, you can easily hurt your hand...
so a couple of light movements with the Dremel and the cutting disc and voila. 
The photo may not convey it well, but to the touch there is no feeling that something is sticking out. Everything is smooth. A self-tapping screw like this cuts off a disc in seconds, with a fountain of splashes.
And I considered the third option for purely everyday use. My son has Railway" In fact, it is plastic, and in the semaphore zone, my son broke off the plastic lever for stopping the train “on red”; it just couldn’t be glued together...
The photo was not there, screenshots from the video so I hid it under a spoiler
Allows you to perform an impressive range of material processing operations various kinds. However, it is impossible to fully realize the potential of such a tool without the availability of appropriate equipment. However, understanding the variety of attachments for drills will not be difficult.
The entire range of accessories for hand drills can be divided into three categories:
- The main one is intended to work for the intended purpose of the tool.
- Additional - expanding the capabilities of the drill.
- Other, allowing to increase the convenience of work, ensure repeatability and manufacturability of processing.
Each type of equipment has its own characteristics of choice and use, so we will consider them separately.
Basic equipment
The direct purpose of drills is to remove material from small areas of a part according to a complex profile and shape. It can be done different ways, having previously determined suitable processing modes. In total, two groups of modes can be distinguished: cutting (milling) and grinding.
Milling attachments
The first and most extensive class of equipment for drills is burrs. various types. All their diversity can be classified according to a number of characteristics, of which the size and shape of the working part are of the most important practical importance. The bur tip can have a needle-shaped, spherical, disk shape, and also have a profile of a flame tongue, a cylinder with a straight and rounded end, a straight and reverse cone.
According to their design, burrs can be divided into solid carbide, steel (including those with a carbide tip), and diamond:
- Solid carbide burs made of tungsten carbide are designed primarily for large material removals, their main working surface is the side. These cutters are usually quite large in size and are designed to maintain cutting properties for a long time. The large size of the burs allows for a wide variety of side surface profiles, which contributes to high-quality shaped processing of grooves and grooves. For solid carbide, the cut pattern of the cutting edges, their size, shape and sharpness are extremely important. There are straight, cross and spiral cuts, which contribute to maximum effective removal chips, depending on which part of the cutter is used as a working part and what material is processed. A separate type of burr - spear-shaped, serving as a kind of analogue of gravers and single-flute cutters, as well as studded ones. These are extremely productive tips for roughing deep grooves and cutting edges.
- Brazed steel burs have a common drawback - poor resistance to lateral loads, which often results in the working head breaking off. The main working surface of such burrs is the end surface; they are designed to form deep grooves and grooves of complex shapes. There may be no soldering, which makes such a burr unsuitable for working with dense and hard materials. The main advantage of steel burs is their relatively low cost with high durability; this tool is most often used in the manufacture of parts made of plastic and soft wood.
- Diamond burs- most universal tool. Thanks to the powder coating, all surfaces of such a nozzle can be equally effectively used as working surfaces. The disadvantage of diamond burs is their low performance at low speeds, as well as their relative fragility when processing viscous and consumable materials. The area of application of diamond burs is the processing of natural and artificial stone, bones and hard steel alloys. The durability of diamond burs is determined by the number of layers of diamond coating (1, 1.5, 2), as well as the degree of coverage of the cutting particles with a binder (35-60%).
Most varieties of cutting equipment are of dental origin, and the notation system was borrowed from there. Burs are distinguished by a colored band on the clamping part, depending on the fineness of processing. Carbide burs and green-banded tips are designed for quick removal large quantity material. Burs without a color designation, as well as with a yellow and white belt, have 8, 16 and 30 cutting edges, respectively. Color coding also used for diamond burrs: black, green and unmarked tips have correspondingly increasing grain sizes for roughing, and red, yellow and white have the smallest diamond grain size for fine finishing.
Sanding and polishing
The second type of processing that drills specialize in is abrasive grinding. In part, diamond burrs could also be classified as grinding equipment, but in reality, during grinding, active wear of the working part occurs, while the powder of the diamond tool practically does not crumble.
Grinding using drills is used on final stages processing and is not intended for removing large portions of material. The characteristics by which grinding equipment is distinguished are the same as those of milling cutters: the size and shape of the working part, as well as the cleanliness of the processing.
Grinding stones are the most common type of attachment for rough processing of simple surfaces. Disc stones are used for grinding external surfaces, cylindrical cutters for internal ones. The color of a stone determines its grain size, but general classification in this matter no, each manufacturer arbitrarily determines the labeling. Grinding attachments are also completely varied and differ in a number of ways:
- The design is one-piece or on a holding rod. The fundamental difference is small: replacement stones are simply more profitable for large volumes of work, but at the same time, serious problems with alignment may occur. It is recommended to use rods and nozzles of the same series, since the landing diameters are almost always different.
- By type of abrasive. There are abrasive natural stones, electrocorundum and silicon carbide on a polymer binder, as well as fine-grained abrasives bound by rubber. Each type of abrasive and binder is used exclusively for a limited range of materials specified by the manufacturer.
- In terms of size and shape, the situation is almost the same as with burrs. In this regard, the choice depends solely on the dimensions and type of the part being processed. By the way, most stones can be easily edited to give the desired profile.
- By the presence of plasticity. Grinding stones can be either completely hard or slightly elastic. The latter property makes it possible to process surfaces with a fine texture, but microscopic particles of the binder can become heavily packed into the pores of the material being processed.
Also included in this category of equipment are polishing attachments. These are discs, balls and cylinders made of felt, felt or muslin. Typically, polishing attachments are replaceable and are used in conjunction with a landing rod. It is possible to mount with a screw or on a cone thread - there is no fundamental difference. Such attachments are designed to work with abrasive pastes: dry polishing is also possible, but for materials such as wood this often results in burns.
Additional equipment
Other types of processing tools can also be mounted on holder rods. This type of equipment is mainly used for rough and preparatory work. We have specially placed this type of attachments in a separate category: they are completely short-lived and rather belong to the category of consumables.
Cutting and grinding wheels
Cutting and grinding wheels can be mounted on a standard rod with a tightening screw. The latter are often made by hand using round cuttings from ordinary abrasive paper. Cutting wheels are designed on the same principle as discs for angle grinders, but most of them do not have a reinforcing cord, which is why they quickly fray and crumble under strong pressure. Diamond cutting discs are the most durable type of additional equipment; they are mainly used for cutting stone and other hard, infusible materials.
Flap-type cylindrical grinding heads, as well as cylindrical clamps for abrasive belts, are widely used. There are also flap sanding discs used for cleaning complex textured surfaces. Metal and polymer-abrasive brushes are especially popular. Disc accessories of this type can also be mounted on rods with a screw clamp.
Features of choosing collets and flexible shaft
All described types of equipment have standard shank diameters of 1.6, 2.35, 3 and 6 mm. Some manufacturers, such as Dreamel and Proxxon, may use individual shank sizes for certain types of nozzles. The problem of incompatibility is solved by selecting collets of the appropriate diameter or adapters. Particularly popular are extended adapters for dental cutting heads. Adapters must be selected for each individual drill, taking into account the diameter of the mounting hole in the spindle.
For greater ease of operation, flexible shafts can be used to provide access for the working body to hard to reach places. Almost all flexible shafts on the market have the same range of characteristics, only the length and diameters of the connections differ. Thus, the flexible shaft can simultaneously serve as an adapter for a different shank diameter. Flexible shafts designed mainly for working with grinding and auxiliary equipment: working with cutters requires a rigid connection to the spindle, while the shaft core has significant radial elasticity.
Other devices
To conclude our review, we will mention some devices whose task is to make work easier and further expand the range of capabilities of the tool. First of all, this concerns vertical feed stands, which allow you to turn the drill into a small drilling machine.
One of the most popular accessories for drills is the milling support platform. This element must be selected individually for your drill model, because quite often the tool and the equipment do not have the same thread pitch and density. On milling sites, the list of housing attachments is not limited: there are also dust collectors, limiters, various kinds of stops and jigs, but their acquisition or manufacture is usually associated with the need to perform some complex processing operation.
Some time ago I received a desired gift - an engraver. Dremel 4000. The box proudly boasted “65 attachments.” In fact, about 20 of them turned out to be discs for cutting plastic, so the variety was not at all what it might seem. Considering the completely inhumane pricing policy of this manufacturer and its Russian dealers, I had to go online. The original attachments, taking into account the cost of delivery, were overtaking the price of the “go to Leroy and buy” option, and besides, the assortment was frustrating. Therefore, we had to look towards China. There were a lot of interesting things there.
Drilling
The kit included a 3.2 mm collet (and another one, which I never used, because the kit doesn’t come with a single attachment for it). And a drill. The same 3.2 mm. But i.e. It's like we have a tool for fine workmanship and a 3.2 mm drill is included. It's a pity that it's not an eight on concrete. Jaw chuck 4486:You can insert 628 drill bits into it:
Or use a set of wood drill bits for a 3.2 mm collet:
The cartridge does not have a particularly good design. As far as I understand, the drill is clamped pointwise, the contact patch area is small, the speed is high, and the drill “bounces” is observed. In addition, on the manufacturer’s website there are a lot of reviews in the style of “out of curiosity, I completely tightened the chuck without a drill, and it no longer wants to unscrew back.”
What do the Chinese offer?
For example, these are the sets:
Visually the chatter is unnoticeable, brass drills wonderfully. I don’t know how many thousands of holes in PCB one drill can make before it wears out, I haven’t tried it. But if you need to make several (dozens) of different small holes, this is an excellent option.
I ordered on ebay from the seller sz_butterfly - he constantly has lots with a fixed price and regularly holds auctions with a low starting price (and not 15 times the shipping cost). A plastic box-stand was included.
Engraving
What's standard in stores?
Milling cutters. A bunch of cutters different sizes and (sort of) appointments. A number of diamond-coated attachments. You can open the manufacturer’s catalog or website and look there.Everything is great, if not for one thing But- price. For example, so wonderful Dremel attachment 7105 (4.4 mm, 2.4 mm shank - the same second collet in the set) costs only 800 rubles for 2 pieces.
What do the Chinese offer?
To start, I ordered a set of a wide variety of diamond-coated drills. Just to understand what I need. 180 rubles with delivery:
It turned out to be a great thing. you can draw thin (and not only) lines on metal and glass. Probably also on plastic. Something like this:
IMPORTANT!!! When working, be sure to wear respiratory protection. I used a regular gauze bandage and constantly wiped the product with a wet rag. During operation, quite a lot of very fine dust is generated. I doubt that the lungs will be happy with such a gift.
In my work, I really liked the spherical shape of the nozzle, because it is easiest for it to maintain good accuracy of work. So I found these Diamond Round Ball Burr Bit Sets:
Or these (300 rubles, free shipping):
Haven't ordered yet. I don't know why I'm being stupid.
Literally a month ago the choice was exactly this - either you buy original Dremel consumables for 500-1000 rubles apiece, or you order from the Chinese. And 2-3 weeks ago, Leroy (I have one next to my office, we go there regularly to look for something tasty) also introduced budget consumables for engravers (for example, mini-sets of diamond drill bits). So the point of waiting for delivery has dropped somewhat.
Offtopic: In addition, there just as suddenly appeared canvases for what the English-speaking Internet calls an oscillating tool, but in our country it is called anything, even an electric broom
I hope this post will help someone try to make something with their own hands. It's an interesting process.
Offtopic 2: I also encountered the problem of finding metal for work. We needed brass. In Moscow, a bunch of factories are ready to sell wonderful strips or sheets of brass. From 5000 rubles. Preferably a legal entity. from 10 to 17 o'clock. As a result, on the second attempt, I bought what I needed at the non-ferrous metal collection point.
The engraver's functionality is very similar to a regular drill or grinder, but its main purpose is to process parts with miniature dimensions. Using such equipment and special working attachments for the engraver, you can effectively perform various technological operations, which include drilling, milling, grinding, engraving, etc.
The list of materials that can be processed using an engraver is also quite extensive. This is soft and malleable wood, hard steel, fragile glass or ceramics, different kinds plastic and even bone. Naturally, for processing using an engraver various materials different working attachments are used, differing in both design and material of manufacture.
What are engraver attachments?
Working attachments or tools used to work with an engraver are presented in a wide variety on the modern market. Their design includes two main elements:
- a shank with which the tool is fixed in the chuck of the equipment used;
- the working part, which performs the main functions, interacting with the material being processed.
The choice of working attachments for an engraver is influenced by the following factors: characteristics of the material being processed and the list of technological tasks that need to be performed. Those home craftsmen and specialists who work with an engraving machine on a regular basis try to immediately purchase a set of attachments for the engraver, which includes tools of various sizes and purposes. Depending on the needs and financial capabilities of a particular engraving artist, this may be a more modest set, including several dozen necessary tools, or a professional set, which contains attachments for performing various works for metal, wood and other materials.
When choosing working tools for an engraver, you should take into account that some of its models can be installed collet chucks, suitable for only certain attachments trademark. To use such equipment in conjunction with any type of attachments, you will have to purchase universal collets for the engraver, which are also sold in whole sets.
Diamond burs for engraving work
The most popular types of working attachments used to complete engraving installations include diamond burs for engravers. The base of such a tool is made of tool steel, and diamond powder is applied only to their working part. The mechanical characteristics of diamond powder make it possible to successfully use the attachment for processing such hard materials, such as steel, ceramics, glass, artificial and natural stones.
Diamond burs (or cutters) are used primarily for finishing shaped holes. As a rule, diamond consumables for engravers are sold in whole sets of 10–20 tools. various forms and standard sizes. When working with them, you should strictly follow the rules of their operation so as not to damage the diamond coating. IN standard version The shank diameter of diamond type engraving bits is 3mm.
Abrasive tools
Most budget option For use in conjunction with a drill or engraver, there are attachments whose working part is made of rubber and abrasive material. The diameter of their shank is 2.3 mm, and they are used mainly for work on metal, including stainless steel. Abrasive tools are usually sold in sets of 6 pieces and have different working part configurations.
Some manufacturers (in particular, the Fit company) produce abrasive engraving attachments in various colors, which allows the user to easily determine the category of the tool. Thus, red abrasive wheels, intended for working on metal, are made of aluminum oxide, and green ones, made of silicon carbide, are used for processing stone, glass and ceramic products. For the convenience of performing various technological operations, diamond cutters are made with different shapes of the working part, but their shanks always have the same diameter.
Using abrasive attachments for an engraver, operations such as boring holes, grinding surfaces, etc. are performed. These attachments are optimal for use at home; for a professional, their capabilities will not be enough.
Working attachments for grinding and polishing
An engraving machine, as mentioned above, can be successfully used for fine grinding and polishing of products made from various materials. A roller cutter made of felt is used as a working attachment to perform such technological operations. Since felt does not have outstanding abrasive qualities, such a tool is used only in conjunction with special polishing pastes.
Selection of polishing pastes of a certain type, which, according to their characteristics and chemical composition seriously differ from each other, depending primarily on the properties of the material that will be processed with their help. So, grinding hard metal surfaces performed using pastes based on paraffin and polishing powder. Special polishing pastes based on diamond powder of various fractions are intended for work on wood and glass. With their help, you can not only effectively remove scratches from the surface of wood and glass, but also bring the product into a perfectly smooth state. Experts recommend giving preference to those in which diamond powder has a fraction size of 3/2 and 5/3.
Accessories such as felt grinding attachments for working on wood, metal, glass and other materials are successfully used not only in conjunction with a specialized engraving unit: they can be equipped with a dental drill and simple hand-held devices.
Working attachments for professional engravers
A separate category of working attachments that engravers are equipped with are professional series tools. Specialists for whom working with an engraving machine is their main activity, as a rule, have at their disposal entire sets of various attachments that differ in the material of manufacture, design and shape of the working part. If we talk about the most typical composition of such a set, then it necessarily includes:
- cutters for engravers of various shapes, sizes and designs;
- drills that turn the engraving machine into an effective drill;
- diamond, abrasive and felt rollers;
- wire nozzles, with the help of which they clean the treated surfaces from traces of corrosion and other contaminants;
- cutting discs for engravers, which are quite difficult to purchase individually.
The presence of such a capacious set of tools for a specialist who uses an engraver in his professional activities is explained very simply. Frequently perform high-quality and accurate work the smallest details on the surface of the workpiece is not allowed only by a milling cutter, a cutting disc for an engraver and other tools of the same size. That is why, even within the processing of one product, tools often have to be changed, choosing attachments suitable for performing a certain technological operation.
In addition, the presence of a specialist set of tools, which includes drills, cutters, cutting wheels for engravers and cutters of many other types, is an indicator of professionalism and indicates that this is an experienced person who is good at his job. Craftsmen who constantly work with engraving devices choose expensive sets of tools from the professional series also for the reason that they can purchase individual tools from such sets individually (in particular, cutting wheel for an engraver) is quite difficult.
Brief overview of brands
Find today on domestic market engravers and working attachments for equipping them does not present any problems. At the same time, the variety of equipment and tools available for free sale allows you to choose them to suit your needs and financial capabilities.
Professional grade attachmentsThose craftsmen who engrave wood, metal and other materials on professional level and already have the appropriate equipment at their disposal, it is worth paying attention to the working attachments produced under the Dremel and Dexter trademarks. The high cost of such equipment for an engraver is fully justified by its exceptional reliability and durability. One more important advantage What distinguishes a milling cutter, cutting wheel, drill, as well as any other tool of these brands is high processing accuracy.
When choosing Dremel or Dexter working attachments, keep in mind that one such tool can last as long as 10 Chinese-made attachments. The fact that you can find attachments in the assortment of these companies can be found in favor of purchasing fairly expensive but high-quality products from well-known manufacturers for various purposes and standard size. So, these can be various cutters for a drill or engraver, drills of different diameters, disk tools, as well as any other types of cutters designed for working on wood, metal, ceramics, and glass.
Budget modelsCheap but decent quality attachments are offered by the domestic manufacturer, the Zubr company. Behind affordable prices you can purchase sets of attachments that include up to 180 tools of the most popular types, designs, sizes and shapes. These sets contain tools for drilling, cutting discs for a drill or engraver, milling attachments, diamond and abrasive cutters, and much more.
All attachments included in the Zubr brand set are placed in a plastic case, making it easy to both store and carry to the job site.
Nozzles from Chinese manufacturers
There are two opinions about Chinese-made nozzles. On the one hand, their quality and reliability are in question, on the other hand, they cost significantly less than branded equipment. A Chinese milling attachment for an engraver, a cutting disc or a drill bit for drilling will not last long, but it won’t be such a shame to throw them away, given their cost. If a professional works behind the engraver, then even a cheap Chinese cutter will not prevent him from doing the job efficiently (although he will have to change such a tool more often).
Chinese attachments for a drill or engraver can be recommended to beginning engravers, who can use them to acquire their first skills in this matter.
Affordable prices of Chinese attachments allow beginning engravers to purchase large sets “to try”
Homemade attachments for engraving machines and drills
For simple engraving work in a home workshop, you can make a cutter, cutting disc, grinding and polishing wheels yourself. As a simple cutter to equip an engraver or drill, you can use a grooved wheel from a regular lighter or a dowel, on the head of which working teeth are cut. It’s also quite easy to make a working attachment for grinding or polishing: you can use wooden drum with shank, on lateral surface which has sandpaper glued on it.
Many homemade attachments for engraving machines (if they are used for a job that is not too complex work) perform well, while the cost of their production is minimal.
An engraver, or bur machine, is a very necessary and useful thing for those who like to carve wood, stone, metal and so on. But the engraver is good for more than just carving. It can also be very helpful when assembling or repairing something miniature to cut out of metal or plastic the required part, which cannot be cut with scissors. You can also use it to polish minerals or just beautiful stones. There are a huge variety of attachments for an engraver: saw blades, grinding discs, stones of various grain sizes, brushes (both simple and metal), felt discs, various cutters for wood and glass, and also, of course, drills.
Buying such an expensive thing as an engraver is only half the battle (however, making it yourself is also not a tricky matter). During the entire period of use, it is also advisable to update and replenish existing stocks of drills, cutters and other attachments, which are also not cheap. In any case, they (for some reason!) cost more than consumables and attachments for the same standard-sized tool. But you don’t have to buy them all - some attachments can be made quite easily yourself. Of course, such complex tools as a wood cutter, drill or diamond gimlet for engraving on glass are unlikely to be made, but, for example, small saws for cutting wood and plastic, grinding and felt discs can be easily made with your own hands.
Even if you have no skills. I think that anyone can cut out the correct circle drawn with a compass on a workpiece with scissors. In addition, some Consumables You won’t find them in regular stores selling this kind of goods. You have to order and wait a long time for them to arrive, and whether they will come at all... And even if they do come, it is not a fact that they will be of high quality and reliable. The sanding discs I recently received in the mail were so fragile that one of them broke with a little pressure... In general, if you want something done well, do it yourself! Today we will look at several options self-made more durable tool.
Saw blades for wood and plastic
You will need:- Metal circle or piece sheet metal, no more than a millimeter thick.
- Compass and pencil.
- Scissors.
- Drill and drill bits.
- Emery machine with cutting disc.
- Metal bolt with nut from children's construction set, or from a prefabricated electrical plug.
Next, you need to cut the teeth of the disk.
We make oblique cuts along the entire edge of the disk, 3-4 mm deep, and in increments of 2 mm. You can use it.
We do the disk for cutting plastic in exactly the same way, repeating the procedures described above, with the exception of sharpening the teeth. Here the cuts should be made at right angles, two mm deep, and also in increments of two mm.
The teeth should be short and wide. This disc can cut plastics of different densities, as well as plexiglass and textolites.
Sanding and felt discs
You will need:- A thin grinding disc (can be used, or even a piece of debris, but not thicker than a millimeter).
- A piece of felt, 7-10 mm thick (from a felt boot - just right).
- Compass and pencil
- Metal scissors.
- Emery machine.
- Thin bolt with nut.
But it’s probably better to cut the felt with a sharp knife, since it’s quite thick, and I crushed all my fingers with scissors. It is better to cut the grinding wheel either with metal scissors or on an emery machine with the same cutting wheel. Next, we make holes in the centers of the circles, and tighten them on both sides with bolts and nuts.
