Drill cobalt fi 8,5 Inox

Drill 8,5 mm cobalt HSSE Inox. Professional 8,5 mm cylindrical twist drill bit made of modern cobalt HSSE high speed steel. It has 2 central blades, ground cutting edges and spiral grooves for fast chip removal from the drilled hole. Thanks to the properties of cobalt steel and the specific geometric design, the drills have very high cutting properties. First of all, they are very resistant to any mechanical damage (fractures, cracks, chipping), can withstand very high temperatures (up to 670 degrees C) generated during high-speed cutting, and allow very high drilling accuracy.
