Long drill bit for metal 4,3
High-quality long drill bit for metal 4.3 cylindrical with a diameter of 4.3 mm, made in accordance with the dimensional standard NWKb, DIN 340. It has special chip grooves responsible for rapid removal of chips from the drilled hole, strong cutting edges resistant to impact and lateral forces, a tip angle of 118 degrees and 2 central blades. Long drills for metal 4,3 of this type are produced from special HSS high-speed steel, which is characterized by very high cutting properties. First of all, cylindrical drills from this steel are extremely resistant to any mechanical damage (fractures, cracks, chipping, dulling). They allow very accurate and high-performance machining. The blades retain their cutting capabilities even under very harsh machining conditions, even at the high temperatures created when drilling at high speeds. The drills are suitable for machining unalloyed steels, metals, metal alloys, copper, aluminum and plastics. Recommended for professional machining using conventional drills, lathes and milling machines, as well as computer numerical control machine tools - CNC.
