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

Drill bits intended for drilling through and blind holes. They have two central cutting edges ground at a 135° angle and flutes that effectively evacuate chips upward from the hole.

TiN-coated drill bits are particularly intended for machining difficult-to-cut materials. The use of a TiN coating results in increased drill hardness, allows faster cutting and enables better surface quality of machined parts. The titanium nitride layer, by reducing friction, decreases cutting-edge wear and thereby extends drill life.

The drill bits are packaged in a plastic container with a hole for hanging on a hook.
