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.
Soft attachments
Plate nozzle
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.
Advantages and disadvantages
When evaluating the effectiveness of drill bits designed for sharpening drills, it should be remembered that such a device is not suitable for intensive use. If you do not impose too high requirements on such nozzles and use them for their intended purpose, that is, for prompt sharpening of drills in the field or in a home workshop, then there should be no special complaints about their work. In addition, one should take into account the fact that the cost of such nozzles is low. This only adds to their advantages. It is also important that due to the simplicity of the design of such a device, it is possible to learn how to work on it quickly enough, even without the skills of performing sharpening operations.
Generally, the bits can sharpen drills with common diameters ranging from 3 to 10 mm
Among the disadvantages that such a device has, the following are usually distinguished:
- Nozzles, which are positioned by manufacturers as a tool for sharpening drills, are more intended for straightening sucked cutting edges. If you perform a full-fledged sharpening of very blunt drills on such a device, then the emery wheel with which they are equipped will not be enough for long.
- Most of the models of attachments offered today are characterized by not very reliable fixation on the drill chuck.
- The angle at which the drill is sharpened is already incorporated in the design of such a device, and it is almost impossible to change this parameter.
- When buying such a nozzle, it is not always possible to try it on for a drill chuck of a certain model. Because of this, many users are faced with the fact that the rotating chuck of their drill hits the inner surface of the adapter.
- If you do not use a homemade bracket, with which the drill is fixed during operation, complete with a nozzle, such a device is not very convenient to use: you have to simultaneously hold the drill with your hand, turn it on and off, and manipulate the drill with your other hand, directing the tool into the holes in the device cover
Design features
The design of drill bits, intended for sharpening drills, includes a plastic case, in the inner part of which an emery wheel with a working surface of a special shape rotates, which allows you to form the required sharpening angle on the working part of the tool. The rotation of the emery wheel is provided by a drill, with the shaft of which the nozzle is connected by means of a special coupling.
Most modern models of drill bits for sharpening tools are equipped with an end cap on the body, in which holes of different diameters are made, designed for sharpening drills of different sizes. These holes are made in such a way that the tool, the working part of which is inserted into them for sharpening, can come into contact with the surface of the emery wheel only in a certain position.
Drill sharpener design
Drill sharpening performed with such a nozzle is carried out as follows:
- The drill, the cutting part of which must be sharpened, is inserted into a hole of the corresponding diameter in the nozzle body.
- The drill starts to work, after which the emery wheel begins to rotate. One half of the cutter is sharpened.
- The tool is rotated in the hole of the accessory by 1800, and the second cutting edge is sharpened.
The above procedure is performed several times until the cutting part of the drill is brought to the required parameters.
An attachment for sharpening drills, installed on an electric drill, can have a simpler design, in which there is no cover with holes, which acts as a jig. It is inconvenient to use nozzles of this design, since you have to keep the tool being processed on weight and constantly monitor the correct sharpening of its cutting part.
Drill sharpener for sharpening drills, chisels, cutters and screwdrivers
The drill attachment used for sharpening the tool can be made independently, which is successfully done by many home craftsmen. The design of homemade drill bits for sharpening drills is not much different from the device of serial models and, as a rule, includes the following elements:
- The body of the device, which can be made of metal;
- A mounting ring or coupling, which are necessary to connect to the drill chuck and communicate the torque to the working body of the nozzle;
- An emery wheel, the working surface of which must be conical, for which a lathe is used;
- Fastening elements for the emery wheel;
- The top cover, which acts as a conductor, providing convenience and correct sharpening of the tool.

In addition to drill bits used for sharpening drills, the modern market offers devices that are designed to restore the geometric parameters of the cutting part of other tools. These include, in particular:
- Attachments designed for sharpening circular saws;
- Devices with the help of which knives are sharpened from planers, chisels and other tools of this type.
Attachment for sharpening drills on a drill device design and application features
On the modern market, there are many accessories (attachments and attachments) that allow you to turn an ordinary electric drill into technical devices of various functionality, a lathe and a milling machine, a pump, a circular saw, etc. One of these devices is a drill attachment for sharpening drills, which allows you to successfully drive the tool in working condition even in cases where there is no traditional sanding machine at hand. Of course, such a nozzle is not capable of completely replacing an emery machine, but it copes well with the tasks of restoring the geometric parameters of a tool in a home workshop.
