Black-and-gold metal drills made of high-speed steel 4341 HSS, coated with TiN (titanium nitride). Drills compliant with the DIN 338 standard. Cylindrical shank.

Drills intended for drilling 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 particularly intended for machining difficult-to-cut materials. The TiN coating increases the drill hardness, allows faster cutting and helps achieve better quality of machined parts. The titanium nitride layer reduces frictional force, which decreases cutting-edge wear and thus extends drill life.

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