Gold-and-black metal drill bits made of high-speed steel 4341 HSS, coated with a TiN (titanium nitride) layer. 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 from the hole.

TiN-coated drills are particularly intended for machining hard-to-cut materials. The TiN coating results in a increase in drill hardness, allows speeding up the cutting process and helps achieve better quality of the machined parts. The titanium nitride layer, by reducing friction, decreases blade wear and thereby extends the drill life.

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