HSS 4.80 mm black-and-gold metal twist drill bit – Pack of 10
Package quantity: 10. This product is sold only as one complete package. The price shown is for one complete package.
Black-and-gold metal drill bits made of high-speed steel 4341 HSS, coated with TiN (titanium nitride). Drill bits compliant with DIN 338. Cylindrical shank.
Drill bits 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 accelerating the cutting process and enables better surface quality of machined parts. The titanium nitride layer, by reducing friction, decreases edge wear and thus extends the drill's service life.
The drills are packed in a plastic case with a hole for hanging on a peg.
