Black-and-gold metal drill bits made of 4341 HSS high-speed steel, 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 an angle of 135° and flutes that effectively evacuate chips upward from the hole.

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

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