Gold-and-black metal drill bits made of high-speed steel 4341 HSS, coated with TiN (titanium nitride). The drills comply with DIN 338. Cylindrical shank.

The drills are 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 out of the hole.

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

The drills are packed in a plastic container with a hole for hanging on a hook.
