Drill cobalt fi 17,5 Inox
Drill 17,5 mm cobalt HSSE Inox. Modern NWKa, DIN 338, twist drill bit with cylindrical shank. It is suitable for drilling through-holes and blind holes in very hard and hard-to-machine materials. The drill bits offered to you are made of specialized cobalt HSSE high-speed steel, and the addition of 5% cobalt increases the drill bit's hardness and wear resistance. The drill bit's cutting edge can withstand high temperatures (up to 670 degrees C) generated during high-speed cutting. The ability to increase cutting efficiency makes the machining time significantly reduced. In addition, the blades are resistant to breakage, cracking, chipping and dulling. Cobalt high-speed steel drills are much more durable than conventional tool steel drills, thus they are recommended for all professional drilling work in large locksmith shops. Drill 17.5mm cobalt is recommended for drilling machines, lathes, milling machines and CNC computer numerical control machine tools.
