Rolled HSS 22.00 mm black & gold metal twist drill bit
Black-and-gold rolled metal drill bit with reduced shank made of high-speed steel 4341 HSS, coated with TiN (titanium nitride). The drill complies with the DIN 338 standard. Cylindrical shank, reduced (podtaczany), which allows using a drill of a larger diameter than the drill chuck's range.
The drill is intended for making through and blind holes. It has two central cutting edges ground at an angle of 135° and flutes that effectively evacuate chips upward out of the hole.
Drills coated with a TiN layer are intended in particular for machining hard-to-cut materials. The TiN coating results in a increase in drill hardness, enables faster cutting and allows achieving better quality of machined parts. The titanium nitride layer, by reducing friction, decreases tool wear and thus extends the drill's service life.
The drill is packaged in a plastic container with a hole for hanging on a hook.
