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

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

Drill bits coated with a TiN layer are particularly intended for machining difficult-to-cut materials. The TiN coating results in increased drill hardness, allows accelerating the cutting process and enables achieving better quality of machined parts. The titanium nitride layer, by reducing frictional force, decreases cutting-edge wear, and consequently extends the drill's service life.

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