Rubber Drill Bit For Removing Adhesive Tape

Types of grinding attachments for a drill and screwdriver Attachments for a drill for grinding: main varieties, purpose, materials and design. Applications, limitations and features of use. Recommendations for choosing, useful tips for working and making your own hands.

Drum or cylindrical nozzles

End caps

Abrasive end nozzles for drills are one of the types of locksmith tool cutters, which are used for manual grooving of profile surfaces, widening holes and removing excess metal in hard-to-reach places. Such a roller cutter is a cylindrical shank, at the front end of which an abrasive head is pressed. And the name end face is associated with the fact that processing with such a tool is most often performed in the perpendicular direction. End bits are available with a wide variety of heads: round, conical, cylindrical, parabolic, etc. Therefore, you can always choose a cutter, the geometry of which is most consistent with the processed profile. The material of the abrasive heads is various grades of high hardness emery stone. In a fixed drill, cylindrical cutters can be used to sharpen locksmith tools.

• Soft attachments

• Disc and fan nozzles

Flap wheels are also used as attachments for drills. They consist of many identical strips of sanding paper, fixed at one end to the axis of rotation, resulting in a dense circular brush of abrasive lamellae. For their external similarity, such nozzles are called fan-shaped in everyday life.

Applications of Drill Grinding Bits

Grinding attachments for drills in many cases quite successfully replace specialized grinders, which allows the home craftsman to do with a minimum of driven tools when solving their tasks. For example, you can use a wire brush to remove rust or old paintwork, then sand the surface with a plate of abrasive paper before and after priming, and then polish the paint with felt or felt. If it is necessary to install such a nozzle 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 cutters of various shapes allows you to bore a hole in the metal to the desired size or give it the required shape. These drill bits come in many shapes and sizes, so you can always choose the one that matches the size and shape of the profile being machined. Grinding discs and drums are often used with a drill fixed with special devices in a horizontal or vertical position.

What are the drill bits for polishing, grinding and deburring

The process of polishing and grinding differs in that the first option provides for finishing, and the second is used to clean the surface from corrosion, varnish or paint, etc. According to the material for processing, it is necessary to select the appropriate nozzles.

The nozzle is a specialized device of various types. To understand which nozzle should be taken to process the corresponding materials, you need to understand their existing types. Drill bits for polishing, sanding and deburring are of various types, which will be discussed below.

Plate

Simple plate attachments for polishing and grinding. To accomplish these tasks, the attachment must be fitted with the appropriate material in the form of a soft disk. The device has the shape of a plate, from which the name appeared, with a shank for fixing an electric drill or screwdriver into the chuck. The shank is fixed with a threaded connection, therefore, when unscrewing it, the nozzle can be used on the grinder.

The tray attachment is an adapter to which the corresponding discs are attached. With these discs, the appropriate processing is carried out grinding, polishing or even deburring. The discs are attached to the plate attachment with Velcro, which is another great advantage; they can be quickly and easily changed. Discs are abrasive, and depending on their grain size, appropriate processing methods are performed. There are also woven discs such as felt discs for fine polishing of glass, paintwork, etc. Plate nozzles are available in different sizes, which allows them to be used according to the volume of work. The larger the surface to be treated, the larger the diameter it is better to use a tray nozzle

What are the attachments for and where are they used?

When it is necessary to perform polishing, grinding or cleaning the surface, then special nozzles, which are fixed in the chuck of power tools, such as a drill or screwdriver, will help to solve such problems. Such devices are used in various fields such as mechanical engineering, construction, car repairs, carpentry workshops, jewelry workshops, industry, etc. There is no better tool for polishing a car than a drill with a special attachment for it.

The drill polishing attachment can be used to process all kinds of materials: metal, ceramics, concrete surfaces, marble, granite, glass, wood, plastic, etc. If there are small scratches in the paintwork on the car body, they can be removed with a grinding attachment fixed in the chuck of the power tool.

End

End attachments for drills are also used as grinding devices. They come in different shapes and are made from abrasive materials of different roughness. Serve exclusively for cleaning and sanding surfaces. End bits are analogous to hand files and are used to increase hole diameters, remove burrs, and fine-tune material. End nozzles are also called cutters, since they are more intended for roughing.

Structurally, the end cutter consists of a cylindrical shank, as well as abrasive material of various shapes. Depending on the shape of the abrasive head, the attachment is used for the respective task.

Disk

They got this name due to the fact that they have a disk-like design. Disc or petal nozzles are analogous to cup and plate devices. They represent a base in the form of a steel disk, to which brushes are attached from the center to the edges. There is a cylindrical shank for installing the nozzle in the power tool chuck.

Disc devices use metal bristles. It is possible to use devices with the location of the bristles not only on drills, but also on grinders (special piranha brushes are produced for angle grinders). They are convenient for processing structures in corner places.

Fan-shaped

This is a special kind of factory tool for polishing and grinding the viscera in pipes. For this, devices are produced not only of different diameters, but also with abrasive sandpaper of various roughness. It is a tool tip (shank) for secure fixation in the chuck of a power tool, as well as a base to which sheets of sandpaper are glued around the circumference.

When the fan nozzle rotates, the inner surface is processed due to the contact of sandpaper with pipe walls and other similar types of structures. When using fan-shaped devices, it is important to select them correctly for the corresponding pipe diameters. If you choose the wrong nozzle, then it will quickly fail due to the accelerated abrasion of the abrasive layer on the sandpaper. Fan nozzles are not expensive, since they have a short service life.
