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

Drill bits are intended for making 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.

Drill bits coated with a TiN layer are especially intended for machining hard-to-cut materials. Applying a TiN coating results in increased drill hardness, allows faster cutting and enables better quality of machined parts. The titanium nitride layer, by reducing friction, decreases blade wear, and consequently extends the drill's service life.

Drills are packaged in a plastic container with a hole for hanging.
