The grinding attachments for the drill differ in shape and material, but all of them have one common feature – a cylindrical rod which is clamped into the chuck. An abrasive or grinding material is attached to the rod. The grinding nozzle usually has a form of a circle or a cone. Nozzles work according to the file principle. Using grinding stones and other nozzles you can enlarge the hole diameter, remove the notches and make the edges smooth.Due to the large selection of different drill bits, this versatile device can replace many other tools. For example, grinding discs allow you to exclude the need to purchase a grinding machine and the nozzle for screws will replace a screwdriver. With the help of drill with different attachments you can perform the following actions: grinding, polishing, cutting, mixing, screwing, milling, drilling holes of different diameters.
