Gold-black metal drill bits made of high-speed steel 4341 HSS, coated with TiN (titanium nitride). Drills compliant with DIN 338. Cylindrical shank.

Drills intended for making through and blind holes. They have two central cutting edges ground at an angle of 135° and flutes that effectively evacuate chips upward from the hole.

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

Drills are packed in a plastic container with a hole for hanging.
