The working part of the drill is made of tungsten carbide.
Possesses high hardness and resistance to abrasion.
The shank of the drill is made of steel, thickened.
Thicker shank with a diameter of 3.175 mm for installation in a standard collet chuck of CNC machines. It is also good to install drills with such a shank in the chuck of drilling machines, unlike drills of small diameters with a cylindrical shank, they are more securely fixed, better centering.
The main application of drills is high-speed drilling of fiberglass in the process of manufacturing printed circuit boards (PCB). Wear-resistant carbide working part provides a long service life of the drill, up to 3000 holes, well withstanding the abrasive effect of fiberglass.
The drills can also be used for metalworking, and a cutting fluid (coolant) is recommended.
