How to make a sanding nozzle for a drill

How to make a polishing nozzle

Modern power tools are convenient to use, but few people know all its functions.

For example, you can use a suitable attachment to the drill for grinding, thanks to which it will not be difficult to cope with tedious work, without spending a lot of effort to perform it.

Since there are all kinds of nozzles for the drill, we propose to get acquainted with them more closely.

Advantages and weaknesses

Many manufacturers make sanding accessories, but not all care that the product is reliable. The competition favors cheaper products, so the quality suffers.

Third-grade tools will not last long, so you should not focus on the minimum cost. Although the price of quality nozzles can vary significantly, such a purchase will be less expensive than buying a special tool. Let us pay attention to some criteria.


  • In some cases, only with the help of this device you can grind hard-to-reach area of the surface.
  • It’s handy for sanding small parts.
  • Electric drill attachments are cheaper than specialized tools and appliances.
  • Many grinding attachments can be made by yourself.
  • Less convenient to use than with specialised tools.
  • Some attachments cannot be used without skill.
  • Low performance.
  • Sometimes you can’t do without a drill with adjustable chuck speed.

Because the benefits are more weighty, attachments are popular, and used by many people.

Where to use

Depending on the type of sanding pad purchased, you can use it to

  • clean metal from rust;
  • Remove paint from iron;
  • polish metal;
  • polish painted surfaces;
  • polish lacquered wooden parts;
  • polish glass;
  • Grind the edge of glass;
  • grind small parts;
  • Remove from the metal scale, burrs and fix other defects in places where it is not possible to do it with other tools;
  • sanding workpieces in places where you can’t sand with other tools.

This is an incomplete list that could be expanded.

Suddenly making these three attachments (burs, bits) for a mini drill (boron, Dremel):

The multi-blade sanding brush (“daisy”) on the left is needed for even and silky, (matte, “rough”) sanding the metal. a very useful thing in the household.It can be used to restore any metal surface to new condition.

As a side note, I have a drill press like this:

This is a 24 volt Soviet motor, long and narrow enough so you don’t have to put it in the tube-handle, plus a Chinese collet chuck. Plus a homemade regulated power supply on the KREN12A.

So, to start, we make the simplest, but, by the way, a childhood dream. an electric file (or a rotary nail file):

We forge the roller from the lighter (by rotation of which we beat the sparks out of the silicon) and put it on a rod of some kind. It is desirable that the rod has a thread on the end, so that the roller will stick tightly. Done.

vidos of this and everything else that will be described through text and photos further.

Here I want to impudently note that all three of these tools (or rather how to make them by hand), I invented completely on their own and made 10 years ago. But now I saw on YouTube videos the last 2 years, which people are doing the same (except “daisy”) and they have there enthusiastic Комментарии и мнения владельцев, millions of views, blackjack and whores So I am now angry-pity gets me: my videos with brilliant ideas and really useful tips and crafts Che Che not almost anyone looks, and someone puts and dislikes Subscribe! 1 in karma: LabaKraba (AmolonieX. here in English or no words at all).

For cutting sanding discs from a sheet of sandpaper pancher (hole punch) and circular knife:

Hole punch is two boards with a gap of two millimeters between them and a hole for a drill on 1.8 mm (you need 2.0 mm, but in the process of making the hole will turn a little). The back end of the drill bit is sharpened to have a sharp edge.

On the end of the drill, which will be pressed, you need to put a cap under the finger, through the paper, to tighten.

A circular knife is just an arbitrary iron plate with bent and sharpened ends. Bottom line, we have:

Very straight and without interfering bent edges (which will be if you pierce with an awl) the central holes are obtained. Use a circular knife to cut circles quickly and evenly enough.

Well, and the hit of the program. making sandpaper petal brushes.

We take the sleeve from the spool of thread. In the video, the outside diameter of this tube was 12.6 mm, but it turns out they vary a lot in diameter, and here’s another one in this picture, with a diameter of exactly 12.9 mm, t. е. exactly what is needed. We wind on it two strips of paper crosswise with glue between them and get a paper tube. the basis for the “daisy”. which we cut into sleeves (top-right in the photo).

By gluing 13mm x 20mm sandpaper tips on these bushings with a strong joiner’s glue. And not orthogonal, as in the sold in the store, but as if they overlap. We have:

Let’s write the grit size on several petals. Done. Sometimes the petals fly off (see “Grits” in the photo). (see the photo above), so it’s better to use sandpaper on a cloth base. Plus wet the petals with soapy water before use, otherwise they will get salted (clogged with shavings) and spoil the evenness-silkiness of the grinded metal texture by these places.

Here someone might notice that similar brushes (only with short blades) are sold on Aliexpress. But I remind you that I figured out how to make them (glue the petals tangentially to the sleeve, not orthogonal) and did, 10 years ago, when there was no Aliexpress.

The video at the end shows what texture is obtained on the aluminum plate by using these 3 brushes of grit 40, 80, 500. The best is 500. just such a pleasant to the touch silky matte texture Grind it strictly in one direction!

Making nozzles with your own hands

If no suitable option is available on the market, for a disc with a high level of rigidity, a soft layer can be made of a large thickness and placed between the velcro and the plastic base. With a stationery knife you need to cut the Velcro, where the soft layer will be glued. For the soft layer is mainly used bath sponge. Keep in mind that the 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, which has a suitable diameter size, and apply the thread on one side of it. On this side you need to fix the disk, which is surrounded on both sides by a wide nut and a limiting washer. This device has no difficulty in making and can be used to treat different surfaces.

Nuances of use

You can buy the nozzle on the drill for polishing cars in any store that sells products for cars. But choose these attachments with care.

New car body elements are made using modern technology. The metal is coated with an anti-corrosive compound and paint, which is characterized by wear resistance. They will serve for about 15 years. But such coating is better preserved if properly cared for. Polishing tool provides the restoration of the original shine and removes defects from the surface. Combined with a special agent, it is cheaper than in a repair shop.

Homemade devices

It is not only the desire to save money that drives a person to create a homemade nozzle. sometimes the right tool is simply not available, and then we have to design and invent. In this section we will show some variants of nozzles, which can be made at home from improvised means.

Based on a car valve

To make such a nozzle you will need one or more car valves with a flat bottom. The big one is better to make from a truck exhaust valve.

The surface should be degreased and glue the head of the desired shape, which can be made of wood, dense foam, rubber and other suitable material, and then glue to the valve with epoxy or polyurethane glue.

Now you need to cut circles from sandpaper. The nozzle turns out to be 5.5 cm wide. let’s cut out the same circle under it. Not reaching the center, the sides are made incisions, and stacked so that each petal came in on the other (in the course of rotation of this device).

make, sanding, nozzle, drill

Thermal adhesive was used to glue the sandpaper.

After sticking the sandpaper the edges of the petals are fixed with staples.

The nozzle coped with the work perfectly, but quickly clogged up, as used fine-grained sandpaper.

Hence the conclusion. you need to make several attachments, so you can do different types of work.

A simple tool from a screw

To make this attachment you need a long screw, 2 washers, a nut, and a few pieces of sandpaper.

A washer is put on the screw. Having cut the sandpaper into squares, a hole is made in the middle, and all the workpieces are put on the screw. Then comes the turn of the second washer, and the whole set is clamped by the nut.

Inserting a device in the drill, it can grind the cavities of wooden parts.

The disadvantage of such a device is a jamming of the thread by the drill chuck, resulting in a problem with the re-setting of sandpaper. Unnecessary part of the thread can be removed or to do on a screw 3 slits. for them will be clamped by the chuck of the drill our home-made attachment.

Basic rules for the drill and attachments

When using an electric drill, as with any other power tool, the operating instructions and safety precautions must be strictly followed.

  • The workpiece must be held securely in place before machining.
  • The bit must be firmly seated in the chuck. Do not operate the core drill if it has a backlash.
  • Hold the drill with both hands, especially the powerful models.
  • The pressure must not be excessive.
  • Do not turn the drill into reverse before it has come to a complete halt.
  • Personal protective equipment. gloves and goggles. must be worn when working.
  • After completion of work for a while can not touch the drill or other tip, because you can get burned.

Notice! Do not try to make nozzle or adapter by yourself. The fact that power drills work at high speed, and as a result, a poor quality or unbalanced nozzle can cause injury.

Observing these uncomplicated injuries will make the work safe, which is the most important thing in any construction operations.

Overview of wood drill bits: drills and core bits

Drilling is the main function of the drill, for which there is a huge range of removable accessories, available as single units or as complete sets. The most common types of bits used for this purpose:

Metal drill bit: types, sizes, methods of application

Technical design and method of application. Types of cutting edge. Drill bits Bosch, Enkor, Zubr, Fit. Correct use of the tool.

The Forstner bit has a wide cutting surface on each side. A point is provided for centering this tip. This type of attachment is used for shaping medium- and small-sized holes in wood. The point does not go all the way through the material. The presence of a tip allows to achieve high accuracy in creating holes for mounting hinges.

Feather drill bits are designed to make wide holes, which can be up to 6 cm in diameter. These bits make it possible to install hardware in slab wood materials and even in solid wood. Drill bits like these are equipped with wide side feathers and a centering point. Thanks to this flat-shaped design, the indentation is precise, while the depth of the hole is limited.

Förstner drill bits for drills are suitable for small to medium holes in wood

Core bits. complexly designed bits for drilling out material. Their cutting surface has a characteristic profile, is wide and has a high safety margin. They work according to the pick principle, or in some cases, with several picks. They are used to make holes up to 10 cm in diameter. The drill bit is positioned in the center of the tip. It is used to set the first hole, which centers and guides the nozzle. Not only can drill bits be used on wood (chipboard, particle board, solid wood), but also on metal, and concrete.

Note! When selecting any type of nozzle, you must always consider the size of the chuck of the electric drill, on which it will be installed.

Depending on the configuration, drills can be used as drill bits for concrete, wood, and metal. Tips with a high safety margin are called pobeditovye. This group of tools includes attachments designed for percussion and vibration equipment.

How to make a grinding nozzle on a drill

There are various attachments for manual and machine sanding. All of them can be divided into two main types.

  • Tools that perform the processing of the part itself. handheld devices, which include sanding blocks (pads, bars) and sanding attachments on the drill or angle grinder, which are all kinds of supporting plates and drums.
  • Devices that ensure the required position of the sanding tool relative to the workpiece. guides, support surfaces, etc.п.
make, sanding, nozzle, drill

Devices for dust extraction, which cannot be neglected either, because of the abundance and harmfulness of grinding dust.

Manual sanding tools

The simplest manual devices include sanding pads, which may be called: sanding blocks, sanding blocks, etc.п. Depending on their shape, they can be used for both flat and profiled surfaces.

Sanding pad consists of three main elements. the body with a working surface on which the sandpaper is stretched, the clamping mechanism that secures the sandpaper on the pad, and the handle, to which the force is applied when sanding. The latter may not exist as an independent element, in which case its role is performed by the housing. The clamping mechanism may also be replaced by other elements performing its function, for example, or velcro.

Many types of proprietary pads are available, which differ from each other in shape and method of attachment of sandpaper. The body is most often made of plastic, with the worktop covered with a soft material to smooth out any irregularities.

The simplest sanding blocks for grinding are not difficult to make yourself. The best material is wood. It is desirable to paste or upholster the working surface with soft material, like felt.

The simplest design of the block is two pieces of board or chipboard, tightened to each other with screws. so that the skin tightened the lower piece, and its ends are clamped between the parts.

If you put a little more effort, you can make a more functional bar, in which the sandpaper will be clamped by a wing nut, which is much faster and more convenient than using screws for this.

For processing large surfaces, if for some reason the power tool is not suitable, it is best to make yourself a sanding “planer”. Its possible construction is shown in the picture below. It is so simple that it needs no explanation. Device dimensions are determined by the specific conditions of work. the parameters of the processed plane and the physical data of the employee.

For grinding edges that are positioned at exactly 90° to the adjacent surface, it is useful to have a device that makes it possible to achieve the required right angle. It is shown schematically, a specific implementation can be any.

One of the main problems in the manufacture of homemade bars is a reliable attachment of sandpaper to them. In addition to mechanical clamping (using screws, nuts, etc.), the workpieces can be fastened with screws and nuts.п.) in homemade sanding blocks, you can use other ways of fastening sandpaper.

You can just nail it on the ends with small nails. The method is easy to use, but inconvenient if frequent changes of sanding pad are necessary.

An acceptable way to attach sandpaper is to glue it on. For this purpose, adhesives are suitable, allowing relatively easy separation of the sandpaper from the base for its replacement.

Sometimes you can use wedges to fix the sanding plate. In a bar one makes a kerf, into which the edges of the skin are set and the wooden wedges are inserted. The kerfs and wedges can be of different sizes.

Attachments for drills and angle grinders

These nozzles represent a disk of plastic or rubber, to which the sandpaper is attached in the form of a circle. Plastic plates have a soft or not so soft layer between the base and the velcro, for better adhesion of the skin to the surface to be treated. Plates for drills have a shank in the form of a rod, for angle grinder. a thread for screwing them on the output shaft of the angle grinder. The grinding attachment for angle grinders can be turned into a drill attachment by screwing a shank adapter into it.

But because of the stiffness of the nozzle for angle grinder, strictly vertical positioning of the drill relative to the plane when grinding is almost impossible.

When using a rigid platter (flexible to work easier), any slight inclination leads to digging the edge of the platter into the workpiece and trying to pull the drill out of his hands, which increases the inclination and deeper digging the edge of the circle. It results in a clearly visible indentation on the machined surface.

Therefore, only sanding attachments capable of compensating for the inclination of the drill are suitable for the drill: either rubber, or with a thick soft layer between the plastic base and the Velcro, or having a movable pin attachment.

Strengths and weaknesses

The main advantage of the attachment is that it extends the functionality of the tool already purchased. Additional surface finish options do not require the purchase of expensive specialized equipment.

Advantages of a drill bit compared to specialized equipment:

  • Grinding quality hard-to-reach places;
  • easy work with small parts;
  • saving money;
  • the possibility of making their own hands.
  • not as easy to work with as a special tool;
  • For quality grinding it is necessary to acquire the skill;
  • lower productivity;
  • often requires adjustment of rotation speed.

If the amount of work is small, the advantages many times outweigh the disadvantages.

How to use nozzles

The main uses of drill grinders are as follows:

  • scraping surfaces of rust, residues of old paint and other contaminants before painting;
  • polishing metal surfaces;
  • polishing of paint coatings;
  • polishing glass or plastic (e.g. car headlights);
  • glass edge grinding;
  • deburring of metal parts after welding;
  • sanding surfaces in hard-to-reach places.

For tightening screws

Perhaps this is the simplest and most popular nozzle of all existing, in fact, it is a hardened bit with a cross for different screw sizes. It is enough to clamp it into the chuck, and an electric drill can easily replace an electric screwdriver. The only condition for using the nozzle. the drill must have a speed regulator.

complex devices are also available for sale, allowing to screw screw in screws at different angles. Special mention should be made of flexible devices with a sheathed wire. They can be used to work in the most inaccessible places.

Screwdriver bits

Drill bits differ in their function:

Parallel stop is used to adjust the depth of the drill. And there are also special drill stands, thanks to them you can securely fix the tool without getting hurt.

The drill does not only have a drilling function. It can be used to make blind holes, for example, to install the hinges in wooden furniture. The Forstner drill is perfect for this operation. The hole will turn out flat, and the edges are perfectly smooth. And you can also use feather drills instead of Forstner.

Cutting nozzles

Surely those who used in their work angle grinder, noticed how sloppy this tool cuts the material to be processed, there are still nicks. But if you use a special drill bit that can cut metal, you can notice that the work will be done more delicately and without damaging the metal. Such a device is driven by the chuck of the tool on which it will be installed. If it is necessary to cut the metal, it is better to choose a drill with the number of revolutions that is approximately 2800 rpm.

Advantages and types

The cut will always be very even, it is comfortable to work, the attachments are easy to maintain and apply, no adjustments are required.

There is a very handy tool on the drill, called “Cricket”. It is a die cutter that has two cutting heads. Such a device is used in order to cut thin sheet metal:

“Cricket” is very helpful to the owner of the plot, who has decided to install a fence made of metal profile.

Cricket” is used for sheets of materials that have these parameters:

After processing, the surface will be smooth, no nicks will remain, the coating will be completely intact.

If you want to make a good, even cut on the inside, you have to drill a hole there first.

The nozzle matrix is constantly rotating, which means that you can work with it on both vertical and horizontal surfaces. To use the tooling, it is recommended to buy a drill that has 3k. revolutions per minute. The minimum number is 1,500 rpm.

To cut profile sheet metal or shingles, you can use the “Steel Beaver” nozzle.

The principle of operation will be similar to the previous nozzle, but the cut will be made by frequent reciprocating motion of the punch, which will bend the metal and break it against the die. With this type of tooling, it is very easy to make straight cutters and also, if necessary, curves.

The cutting radius is 1.2 cm. This tool is distinguished by the fact that you can work with it at absolutely any angle. If you compare it with the “Cricket”, it is able to cut metal, which has a greater thickness. 1.8 mm. The advantage of the nozzle is considered a very even cut, as well as during the work there will be absolutely no sparks, the metal will not be deformed.

When the metal cutting is finished, you need to move it very carefully, because the cut edge will become very sharp.

The use of the polishing wheel

Using the polishing wheel on the drill, you can renovate the look of your car. This procedure is most effective if you need to smooth out small chips or remove surface tarnish.

The work is performed in 2 stages:

Also perform protective treatment to reduce the negative effects of different types of precipitation and ultraviolet. It is mainly done when preparing a car for sale. The protective layer, which is made up of a wax or silicone, is applied to the bodywork to form an invisible film that repels moisture, and makes the bodywork shine. You can polish a used car with a soft nozzle if there is no damage to the paint on it. It can also be used for careful treatment with a protective agent.

Materials for bodyshop treatment

The following materials are needed for the car treatment procedure:

The cleaner to be used for treating the surface of the bodywork should be chosen carefully. A paste that has abrasive particles is needed to remove the top layer of lacquer. It must be chosen according to the type of cracks and chips on the body. A product with a high particle count is necessary if the defects are very noticeable. Now there are a large assortment of preparations on sale that give the color a bright.

The protective coating on a new vehicle can get dull streaks. In such a situation, it will be enough restorative paste, which has in its composition sanding additive.

A variety of products can solve any problem. For a vertical surface it is convenient to use a thick paste. Any part of the car can be treated with it. In it is often added a component that enhances the brightness of the color.

Polish, which has a liquid formulation, is suitable for horizontal surfaces, for example, for the roof or hood. The main advantage of such a product is that it can not damage the enamel.

It is convenient to use aerosols. They are characterized by cost-effectiveness and effect. However, not very much of the product is contained in the bottle.
