Drill grinding attachments for processing wood and metals

I am engaged in selling various decorative wood products on the Internet. I don’t earn millions, but it’s enough to live on. One of the most popular tools in my workshop is the engraver, which requires attachments that constantly need to be changed and increased in number. I realized a long time ago that homemade attachments are better than purchased ones - they are cheaper to produce, safe to use, and last much longer if they are made with high quality. Now I suddenly remembered all of this and decided to share it with you. So today we will look at how to make attachments for an engraver with your own hands.

Assortment of attachments

The most common products for processing automobile bodies are: sponge-like, abrasive with varying degrees of grain, felt, having a soft surface. They are conventionally classified according to the type of production into two types:

• petal (has high productivity and high price);
• surface grinding (made like a rubber disc with an additional coating for processing).

The material for these items is dense foam rubber or felt, which has different diameters. However, kits are sold that consist of several elements that have different purposes and manufacturing complexity.

Making your own nozzles

If there is no suitable option on sale, then for a disk with a high level of rigidity you can make a soft layer of great thickness and place it between Velcro and a plastic base. Using a utility knife, you need to cut off the Velcro where the soft layer will be glued. For the soft layer, a bath sponge is mainly used. It must be remembered that individual elements can shift, breaking the overall symmetry.
You can also use a felt disc, which is used in a polishing machine and machine. First, you should make a pin with a suitable diametrical size and apply a thread on one side. On this side you need to secure the disk, which is surrounded on both sides by a wide nut and a limit washer. This device is not difficult to manufacture and can be used to process various surfaces.

Kinds

Knowing the features and general characteristics of grinding attachments, we should move on to consider specific models that are often used in various types of work.

The disc nozzles are presented in a similar version of the standard disc nozzles. The only difference between them is the design. Instead of a thread, there is a special fastening pin in the cartridge. In some cases, these pins can be adjusted, allowing you to make smooth movements along the contour of the surface being treated. In addition to plastic material, plate attachments are made of rubber. These models no longer have a movable pin, due to which they are firmly attached to the base of the tool.

• Fan-shaped ones resemble the image of a disk, the edges of which have a special fastening for the processing material. When processing surfaces with difficult access, fan attachments have no equal. It is worth noting their design feature. During operation, the nozzle can apply any required shape, which is very convenient when processing surfaces with complex geometric patterns.
• The polishing model with a soft attachment is mainly made of foam rubber, felt or leather. The fasteners are presented in the form of a pin with special washers for clamping. Quite often these attachments are used in polishing work, especially in auto repair shops.

Application nuances

A drill attachment for car polishing can be purchased at any store that sells car products. However, you should choose these devices carefully.

Body elements of new cars are made using modern technologies. An anti-corrosion compound and paint are applied to the metal, which are wear-resistant. They will last approximately 15 years. However, this coating is better preserved if it is properly cared for. The polishing device restores the original shine and removes defects from the surface. Together with a special product, such a product will cost less than services provided in a workshop.

Homemade cutting wheels

Now let's look at how to make the most common homemade attachment for an engraver.

To begin, take a cutting wheel for an angle grinder, a regular compass, but better with two needles at the ends, an awl and unnecessary scissors or metal scissors.

Using a compass, draw small circles (slightly larger than the standard size of the cutting wheel on the engraver attachment), then cut the circle into pieces from which it will be easier to cut out your circles and, in fact, cut.

Right in the center of the cut out circles, you need to make a hole with an awl using rotational movements. The diameter of the hole should be equal to the diameter of the screw from the engraver on which the nozzle is attached.

Finally, sharpen the homemade wheels on an unnecessary sharpening stone, putting them on the engraver itself.

Such cutting wheels are cheaper than purchased ones, and they last longer than non-reinforced ones.

Homemade cutting wheels for the engraver are ready.

Body polishing

The polishing process can correct only some defects.
If there is corrosion, chips or damage on the body through which the steel frame is visible, then a major repair will be required. Before starting the polishing process, you should carefully inspect the vehicle to ensure that any imperfections can be eliminated.

Treatment of the body with a special device will give a positive result if:

• slight difference in shades that resulted after partial coloring;
• the presence of roughness, scratches and cloudy stains;
• faded layer of paint;
• the appearance of graininess and streaks of enamel.

You need to know that you can’t overuse polishing, because when you do it, the paint layer becomes smaller by 5 micrometers. From the date of manufacture of the vehicle, no more than 20 polishing procedures can be performed. At this time, you need to use a thickness gauge, especially if the car is used.

Using a polishing wheel

By using a polishing wheel on a drill, you can update the appearance of your car. This procedure is most effective if you need to smooth out small chips or remove tarnishing of the surface.

The work is carried out in 2 stages:

• removing paint from the body surface;
• applying polishing compound.

Protective treatment is also carried out to reduce the negative effects of various types of precipitation and ultraviolet radiation. It is mainly done when preparing a car for sale. A protective layer (it contains wax or silicone) is distributed over the surface of the body to form a film that is invisible to the eye, repels moisture, and makes the body shiny. You can polish a used car with a soft pad if there is no paint damage. It can also be used with careful treatment with a protective agent.

Large diameter petal circle

The principle of collecting is the same as the previous one, but with some details.

You still need to take scraps of plywood and cut out circles, but larger ones.

Then fasten them and make eight cuts with a metal saw. Pieces of sandpaper are still inserted into these cuts, but then they are compressed with an elastic band and impregnated with glue or epoxy resin.

Let it sit and dry, then start testing a homemade large-diameter flap wheel for an engraver.

Materials for car body processing

To carry out the car processing procedure, the following materials are needed:

• foam;
• sandpaper;
• grinding compound;
• bike;
• polish.

The product that will be used to treat the body surface must be selected carefully.
A paste containing abrasive particles is needed to remove the top layer of varnish. It must be selected depending on the type of cracks and chips present on the body. A product with a large number of particles is necessary if the defects are very noticeable. Nowadays there is a large assortment of drugs on sale that add brightness to color. The protective coating of a new car may develop cloudy streaks. In such a situation, a restorative paste containing a grinding additive will be sufficient.

A variety of tools allow you to solve any problem. For vertical surfaces it is convenient to use a thick paste. It can be used to process any part of the machine. It is often added to components that increase the brightness of the color.

Homemade drill accessories

Despite the fact that the industry offers a wide range of attachments, both in sets and individually, home craftsmen often make various accessories for the drill with their own hands. Such a desire can be caused by a number of reasons. Some people don’t have a suitable attachment at the right time, others are not satisfied with the quality of those that go on sale.

Drilling angle limiter

A very useful and very simple device is the angle limiter. Separately, it is worth noting that this attachment performs two functions at once. It provides a precise drill angle and limits the depth of the hole.

The main part of the nozzle is a clamp with a thickening in the upper part. The clamp is attached to the drill body. Two holes with a diameter of 6 mm are made in the thickening. A thrust bracket is bent from a wire of the same diameter at the required angle. A stop is attached to the bracket, allowing you to adjust the depth of the hole. It would be useful to make several replacement brackets with the most popular parameters.

For cutting round workpieces

The basis of many homemade products is a circle made of plywood or other sheet material. Most often it is cut using a jigsaw, but the same can be done using a drill. To do this, you just need to make a simple holder that works on the principle of a compass.

The device is a pin that is attached to the drill body with a clamp. The vertical stop moves along the pin and is fixed in the required position. The stop is held on the workpiece with its pointed end, and the rotating drill cuts out a circle. Instead of a drill, it is better to use a cylindrical cutter; with its help it is easy to make a high-quality cut without much effort.

Adapter for miniature drills

The chuck of a conventional drill has restrictions on the maximum and minimum diameter of the drill, and often it is necessary to make a hole with a mini-drill with a diameter of up to 0.1 mm. A standard chuck cannot compress a small shank, but if you first clamp the drill into a collet chuck for an electric motor, and then fix it in the drill chuck, the problem will disappear.

Why do you need to polish a car body?

Polishing is the process of rubbing a car body with special lubricants that protect the paintwork and remove minor scratches. In order for the car not only to be clean, but also to shimmer in the sun, it is necessary to regularly carry out polishing operations. These operations allow you to solve a number of the following problems:

1. Avoid premature destruction of the paint layer
2. Protect the body from corrosion
3. Make the paintwork shiny, which allows you to effectively highlight your car
4. Remove minor scratches and abrasions of the paint layer

To carry out polishing operations, you will need the following set of tools and consumables:

• Power tool - this can be an angle grinder or grinder, drill, screwdriver, eccentric or polishing machine. When using an angle grinder to polish a car body, you need the tool to have a speed control option
• Car polishing nozzles are special devices made of soft materials, through which polishing paste is rubbed into the paint layer of the body. Exactly what types of nozzles for car polishing there are, how they differ, and for what purposes they are intended, is described in detail in the material
• Adapter, mandrel or plate - a device onto which the polishing attachment is attached. Such adapters have appropriate fasteners for installation in the chuck of a drill, screwdriver or on the spindle of an angle grinder and polishing machine. The adapter is used for removable drives, but there are also non-removable devices. They are less popular because they are more expensive. Fixed nozzles are equipped with fastening elements and therefore do not require the use of adapters. It is important to note that the plates are available in diameters of 115, 125 and 150 mm. In addition, they can have a hard and soft base on which a polishing disc is attached. The soft layer on the plate eliminates the beating effect (the vibrations of the power tool are smoothed out), which is especially important when working with sheepskin attachments
• Polishing paste is a consumable material that protects the paintwork of the body, removes scratches, and also achieves shine.

Center cutter

This specific attachment is a type of drill and cutter; it is convenient for cutting and drilling holes in thin materials.

This attachment can be used for cutting small washers from, for example, fiberglass.

To make it you will need a metal block, a drill, a tap, a cutter and a drill.

First, in a metal block (it should be shaped like an oblong brick), drill a hole for a drill and a cutter from the tip of an old small drill.

Then drill a hole in the side for the clamping screws; these holes are driven with a tap.

Next, insert the drill and cutter into place, tighten with clamping screws and you can test.

The do-it-yourself center cutter for the engraver is ready.

Types of polishing work

First, let's understand that car polishing is classified into two main types of work:

• Protective - such operations allow you to ensure reliable protection of the paint layer from minor mechanical stress, abrasions, and even to avoid the varnish losing its characteristics. Pastes used for rubbing car bodies include substances such as Teflon, wax, etc.
• Restoration is the most common type of work in which car owners resort to polishing the body of their car. They resort to restoration work to remove minor scratches and other types of deformation of the body paint, for example, paint fading in the sun. The principle of restoration work is to remove the top oxide layer. For this purpose, special types of polishing pastes are used. After carrying out restoration work on polishing the body, it is imperative to rub the body with protective paste

You need to decide on the type of polishing work in order to choose the right attachments. After all, the quality of work depends not only on the substance used, rubbed into the body, but also on the material from which the nozzle is made.

What types of nozzles for polishing a car body are there?

Depending on the type of polishing work, it is necessary to use appropriate attachments. When using protective pastes, delicate nozzles are used, and if it is necessary to remove scratches and abrasions of the paintwork, you will need to use abrasive devices. The polishing procedure can be carried out using drills, screwdrivers and grinders. To do this, it is not at all necessary to buy special polishing machines. Only when using the power tools in question, one detail needs to be taken into account - they must have a speed control function.

Now let's look at the types of polishing attachments for cars. They are made from different materials, but the most popular are foam and sheepskin attachments.

Types of polishing attachments

By type, polishing attachments for drills can be divided into cup and disk shapes. Cup attachments work with a surface that is perpendicular to the axis of rotation. Disk - a narrow cylindrical surface, which is located parallel to the axis of rotation.

If you do polishing, you know that you need to use special pastes. They are applied to a base made of soft material.

The material used in polishing attachments is fleecy fabric, foam rubber, a special polishing mat from which pads for polishing can be cut, and synthetic materials.

All kinds of brushes also differ from each other. It is customary to divide brushes into hard and soft. Hard brushes are the cheapest and use cable scraps as rust removal material.

They do a good job of removing rust from simple surfaces, especially quickly removing a thick layer of rust that can chip. The second type of brushes is soft brushes.

They are made from long single wires, so they can “bend” surfaces and are used for polishing difficult surfaces. Like all other attachments, brushes come in cup and disk types.

Abrasive nozzles made of sandpaper are divided into those where the sheet of sandpaper is rigidly fixed to the working surface, and those where there are many sheets of sandpaper that have one free end. During operation, the latest attachments can also slightly bend around the surface being processed and work with curved surfaces.

Also, the latter can then be used as a basis for applying polishing paste - when the abrasive layer has already peeled off from the sandpaper. You should only use cloth-based sandpaper for polishing attachments - paper sandpaper will not be very durable.

Abrasive stone attachments are a very common tool in the home craftsman’s arsenal. Usually the drill will not have enough power to pull a regular grinding wheel.

Therefore, they use attachments for large-diameter drills. To work with them, it is advisable to use only a high-speed drill, since such attachments are designed for a shaft rotation speed of 6-12 thousand revolutions.

Felt or felt polishing supplies for car

Felt or felt - felt tips are extremely rare. They are intended for cleaning the body surface before polishing, as well as at the final stage of using polish. Felt nozzles are characterized by increased softness, and they are available in cylindrical and flat shapes. They are not suitable for cases where it is necessary to remove minor defects on the car body. They are used with a drill, screwdriver and grinder that has a speed control function. Their disadvantage is that due to the dense base, the car body heats up.

Sheepskin nozzle for car polishing and its types

Sheepskin attachments for drills and screwdrivers are used to apply a protective layer of polishing paste, as well as remove scratches and other defects. For this purpose, sheepskin equipment is available in different types - regular or classic pile, natural sheepskin, and also twisted pile.

Many people mistakenly believe that sheepskin is intended for finishing or for applying a protective layer. However, this is not at all true. They are intended for starting treatment and removing scratches. After their use, small marks remain, so they are not suitable for finishing. That is why, after using sheepskin equipment, it is necessary to use foam rubber attachments. The length of the pile of sheepskin nozzles ranges from 25 to 40 mm, and the larger their size, the better the cooling.

1. Classic sheepskin.
   The use of classic sheepskin devices makes it possible to achieve a special shine of the paintwork, which is why they are often used at the final stage for almost all car models, from domestic to foreign cars.
2. Twisted pile.
   With twisted pile, sheepskin is intended for rough or aggressive polishing, that is, when it is necessary to remove small scratches and other paint defects
3. Natural sheepskin for delicate processing.
   The equipment is made of natural sheepskin, which is yellow in color, provides the most gentle effect, and is used for finishing. Typically, devices made from natural sheepskin are used to process German-made cars - BMW and Mercedes-Benz. They differ from the first two options in their high cost, which is due to their production from the wool of rare animals

All types of sheepskin polishing equipment are designed to operate at speeds from 400 to 1500 rpm. This speed mode ensures their maximum efficiency and productivity.

Sanding and polishing attachments

Drill attachments for grinding and polishing allow you to perform a wide range of jobs. The main ones are:

• cleaning parts before painting or welding;
• grinding and leveling surfaces;
• final finishing and polishing of surfaces made of metal, wood, plastic or glass, as well as paint and varnish coatings;
• processing the glass edge after cutting.

They allow you to avoid purchasing expensive specialized equipment. It is worth remembering that with a large volume of work, the drill will not be able to provide the required level of performance and will wear out quickly, since it is not designed for constant loads perpendicular to the axis of the working shaft.

Drill attachments for grinding and polishing

Devices for grinding and polishing differ not only in the shape of the working body, but also in the degree of rigidity of its material by:

• hard;
• soft;
• super soft;
• embossed.

It is impossible to complete the grinding and polishing operation from start to finish with just one device. Your home workshop should have a set of such devices.

Foam polishing attachments types and purposes

Foam nozzles are used not only for applying protective, but also restorative polish at the finishing stage. Manufacturers produce foam nozzles in a wide variety. The foam base differs in the size of the cells, and the smaller they are, the correspondingly softer the effect. To remove small scratches from the car body, you need to use foam rubber attachments on a drill and a screwdriver with large cells of increased rigidity. Different colors of foam nozzles allow you to accurately apply the appropriate pastes.

Foam nozzles are available in two types - petal (with a grooved base) and flat. They differ not only in appearance, but also in the quality of surface treatment. Flat ones carry out the same type of surface treatment, while petal ones, due to their protrusions, allow for delicate processing due to the small area of ​​their contact. Corrugated ones are used for applying wax, as well as removing holograms - small marks on the paintwork. The advantage of corrugated tools over flat ones is that they do not heat up the surface being treated too much.

Ground cylinders for engraver

For this attachment you will need a thin but durable cloth, glue, a tube of the same diameter as an engraver attachment and sandpaper.

To begin, wrap several layers of fabric 12 millimeters wide around the tube and soak it with glue.

Attention, do not use wood tubes or superglue for gluing. Superglue sticks the fabric and the tube together too much, it will be difficult to tear it off, and you shouldn’t glue the fabric even with regular glue on a wooden tube, because the glue will be absorbed into the tube and stick the fabric to the tube itself, which will again make it difficult to tear them off.

Cut strips of sandpaper, shaped like a parallelogram, and the width is the same 12 millimeters, the length should be such that the strip covers the entire tube.

Next, wrap these strips on dried fabric, then soak them in glue again and let it sit.

Carefully remove from the tube, put it on the already prepared engraver attachment and you can test.

By experimenting with tube diameters, you can make different sized cylinders to suit different needs.

Homemade grinding cylinders are ready.

What are the pros and cons of car polishing attachments?

Knowing what types of polishing equipment for car bodies are produced, it will be important to consider their advantages and disadvantages. First, let's look at the advantages and disadvantages of foam discs.

• Foam rubber wheels for cars have disadvantages such as heating the surface being treated and high paste consumption
• The advantages of such devices include a wide variety of choices and affordable prices.

For comparison, let's look at the pros and cons of sheepskin attachments for polishing a car:

1. Pros: effective in removing scratches (even the largest ones), they do not consume a lot of paste, which means they have low consumption. In addition, such discs do not heat the surface, which is very important when polishing by beginners.
2. Disadvantages - they do not allow for finishing, as they leave small scratches and holograms. In addition, their price is higher than foam rubber, and there is little choice

Based on the advantages and disadvantages of both types of polishing attachments, we can draw a conclusion about which types should be chosen in specific cases.

Decorative sanding attachment

Also, someone might find a similar attachment useful for decorative sanding made from ordinary cork.

Take the prepared cork and screw a self-tapping screw without a head into its center.

Place a washer on the self-tapping screw and glue it to the base of the plug.

The chuck's jaws will prevent the screw from screwing deeper into the plug during operation, as they will rest against the washer.

How to choose a car polishing attachment

You can perform high-quality polishing of a car body not only in a specialized car service center, but also at home. The quality of the work largely depends on various factors, but one of them is the choice of the appropriate nozzle. When choosing polishing attachments for a drill, screwdriver or grinder, you need to consider the following factors:

1. Manufacturer and price - if you set out to produce high-quality polishing of the car body, then you need to approach this issue with the utmost rigor and seriousness. Buying cheap little-known attachments or without a manufacturer’s name at all is dangerous because you will not only not be able to get the desired result, but will also ruin the paintwork. That is why it is better not to save money and choose equipment from well-known manufacturers such as 3M, Mirka and others
2. Purpose - it all depends on what goals you are pursuing. For protective polishing, soft nozzles are used, and to remove scratches and other defects, abrasive nozzles with a high degree of hardness are used. To polish car headlights, completely different types of attachments are used, so you should not combine them and make them universal
3. Speed ​​of work - this factor also needs to be taken into account, since failure to use the equipment at speed will lead to the fact that you can “burn out” the paintwork of the body. On the nozzles, manufacturers indicate the recommended speeds for their use, which also determines the choice of a suitable power tool for the job.
4. Size or diameter. Round nozzles are produced with a diameter of 115 to 150 mm. It is important to take this value into account if you plan to carry out work using an angle grinder or a grinder. If a drill or screwdriver is used for polishing, then it does not matter much what size the adapter and working equipment are. The larger the diameter of the equipment, the higher the processing speed, however, it is not recommended for a beginner to buy a device larger than 125 mm, since the processing procedure becomes more complicated due to high vibrations and the need to control the surface being processed
5. Type of nozzle - they are removable and non-removable. They differ only in price. Beginners are recommended to use removable attachments, as they allow polishing with quick replacement of attachments.

There is no clear answer to which nozzles are best to use for polishing a car body. To achieve the result, you will need to buy a set of appropriate equipment. However, purchasing such a set is not a guarantee that the work will be done with high quality. Pay attention to what types of polishing pastes for cars there are, and how to choose them (link). To polish hard-to-reach places, for example, cast car wheels, specially shaped equipment is used - cylindrical, conical and others.

To summarize, it should be noted that before polishing a car body for the first time, you must first practice on other surfaces. The wrong choice of nozzle for roughness, as well as rotation speed, will lead to immediate damage to the paintwork. That is why it is very important to be responsible when choosing power tools, polishes and attachments for polishing a car.

Types of grinding attachments for drills and screwdrivers

When grinding work is one-time in nature and there are no special requirements for the quality and accuracy of surface treatment, attachments for drills or angle grinders are used for grinding. In the first case, it is a tool with a conventional cylindrical shank, and in the second, with a threaded hole.

Drill attachments are more common because they are universal and can be used with three-jaw, quick-release and collet chucks, including screwdrivers.

Having several of these attachments, you can successively remove old paint, remove burrs and flashes, rough grind the putty and finish polishing after painting.

Using end attachments for drills, which have a variety of shapes and are made of hard abrasive, samples are made in the profile surfaces of metal products in the lateral and end directions. In addition, they are used for sharpening chisels, knives, drills and other metalworking tools.

Areas of application for drill grinding attachments

In many cases, grinding attachments for drills quite successfully replace specialized grinders, which allows the home craftsman to get by with a minimum of power tools when solving his problems.

For example, you can use a wire brush to remove rust or old paint, then use a pad of abrasive paper to sand the surface before and after priming, then buff the paint using felt or felt.

If you need to install a similar attachment on a screwdriver, use special chucks with a hex shank or adapters. The only limitation of such a tool is the low speed of the screwdriver.

The presence of abrasive rollers of various shapes allows you to bore a hole in the metal to the desired size or give it the required shape.

These drill attachments come in many shapes and sizes, so you can always choose one that matches the size and shape of the profile being machined.

Sanding plates and drums are often used with a drill secured using special devices in a horizontal or vertical position.

In this version, the drill acts as an improvised mini-sharpener, which can be used both for grinding parts and for sharpening tools.

Main pros and cons

Despite the variety of applications, the grinding attachment is still an auxiliary tool.

When working with them, a drill weighing several kilograms has to be held in a perpendicular position and most often suspended, which primarily affects the duration and accuracy of processing.

But many one-time jobs are performed for a short period of time and do not require much precision. And some of them, such as stripping and stripping, are generally uncritical to the type of tool.

The absolute advantage of all drill attachments (not just grinding ones) is their low cost and availability. With their help, you can get a result that, compared to a specialized tool, will be of slightly worse quality and will require longer work, but will cost the home craftsman only a few tens or hundreds of rubles.
