HSS 2.50 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 4341 HSS high-speed steel, coated with TiN (titanium nitride). Drill bits compliant with DIN 338. Cylindrical shank.
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.
TiN-coated drill bits are especially intended for machining difficult-to-cut materials. The TiN coating increases the hardness of the drill, allows acceleration of the cutting process, and helps achieve better quality of machined parts. The titanium nitride layer, by reducing friction, decreases cutting edge wear and thus extends the drill's service life.
Drill bits are packaged in a plastic container with a hole for hanging.
