Black-and-gold metal twist drills made from HSS 4341 high-speed steel, coated with TiN (titanium nitride). The drills comply with DIN 338. Cylindrical shank.

The drills are intended for drilling through and blind holes. They have two central cutting edges ground at 135° and flutes that effectively evacuate chips upward from the hole.

Drills coated with a TiN layer are particularly suitable for machining hard-to-cut materials. The TiN coating results in a higher drill hardness, allows faster cutting, and helps achieve better quality of the machined parts. The titanium nitride layer reduces friction and decreases blade wear, thereby extending the drill's service life.

The drills are packed in a plastic container with a hole for hanging.
