Drill for metal, black-and-gold, rolled made of high-speed steel 4341 HSS, coated with TiN (titanium nitride). The drill complies with DIN 338. Cylindrical, rolled shank, which allows using a drill of a larger diameter than the range of the drill chuck.

The drill is intended for making through and blind holes. It has two central cutting edges ground at 135° and flutes that effectively evacuate chips upward out of the hole.

Drill coated with a TiN layer is intended particularly for machining difficult-to-cut materials. The TiN coating results in increased hardness of the drill, enables faster cutting and allows achieving better quality of machined parts. The titanium nitride layer, by reducing friction, decreases wear of the cutting edge, thereby extending the drill's service life.

The drill is packed in a plastic container with a hole for hanging.
