Categories: Metal drills

The drills are made of rapid steel (grade Р6М5) by grinding out the profile. Sharpening of the cross-sectional edge considerably reduces axial force during operation and allows to drill without preliminary prick-punching. The drills are of 59...62 HRC hardness and used for drilling steels, cast iron and nonferrous metals.
