Gold-black metal drill bits made from 4341 HSS high-speed steel, coated with TiN (titanium nitride). Drill bits comply 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 a increase in drill hardness, allows acceleration of the cutting process and helps achieve better quality of machined parts. The titanium nitride layer, by reducing friction, decreases cutting-edge wear and thus extends the drill's service life.

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