Black-and-gold metal drill bits made of HSS 4341 high-speed steel, coated with TiN (titanium nitride). Drill bits compliant with DIN 338. Cylindrical shank.

Drill bits intended for making through and blind holes. They have two central cutting edges ground at 135° and flutes that effectively evacuate chips upward out of the hole.

TiN-coated drill bits are particularly intended for machining hard-to-cut materials. The TiN coating increases the hardness of the drill bit, allows faster cutting and gives better surface quality of the machined parts. The titanium nitride layer reduces friction and decreases cutting-edge wear, thereby extending the drill bit's service life.

Drill bits are packed in a plastic container with a hole for hanging on a hook.
