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

Drills 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.

TiN-coated drills are especially intended for machining difficult-to-cut materials. The TiN coating results in a increase in drill hardness, allows speeding up the cutting process and helps achieve better quality of machined parts. The titanium nitride layer reduces friction, which decreases cutting-edge wear and thus extends the drill's service life.

Drills are packed in a plastic case with a hole for hanging on a peg.
