Long drill bit for metal fi 9,3

High-quality long drill bit for metal fi 9,3 twist, extended, with a diameter of 9,3 mm, designed for drilling through-holes and blind holes in materials classified in the category P1.2 - P1.3. These include hard unalloyed steels, metals, brass, bronze, aluminum, copper and thermoplastics. Long drills for metal fi 9.3 of this type are very resistant to harsh working conditions and resistant to mechanical damage caused by drilling at high speed (and the resulting high temperature). Their strong cutting properties are the result of the use of modern high-speed steel HSS - High Speed Steel for production. Thanks to it, the drills are very hard and durable. The blades are resistant to abrasion, dulling, breaking, cracking, chipping and other damage. Their manufacture is in accordance with the dimensional standard NWKb, DIN 340. They are suitable for various types of conventional machine tools (drills, lathes, milling machines) and modern computer numerical control machine tools - CNC.
