Long drillfor metal fi 1,2 cylindrical NWKb, DIN 340 for drilling holes in materials classified in the P1.2 - P1.3. class These are carbon steels, metals, non-ferrous metals, bronze, brass and thermoplastics. The offered drills have 2 central blades, strong cutting edges and special chip grooves. These geometric properties of the drills allow the chips to be quickly discharged from the hole, and also make them insensitive to impact and lateral forces. Long drills for metal fi 1,2 are produced from modern HSS - High Speed Steel characterized by high cutting properties. First of all, they are resistant to mechanical damage caused when drilling at high speed during which high temperatures are generated. Even in such harsh conditions, the drill blades are resistant to fracture, chipping, cracking and even dulling. This affects the longer service life of the drill bits. They are recommended for conventional and CNC - computer numerical control - machine tools.
