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.

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

Drill bits coated with a TiN layer are particularly intended for machining hard-to-cut materials. The TiN coating results in increased hardness of the drill, allows speeding up the cutting process and enables better quality of the machined parts. The titanium nitride layer, by reducing friction, decreases tool wear and thereby extends the drill bit's service life.

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