Drill fi 14,3 with cylindrical shank
Drill 14,3 mm HSS. Modern twist drill, cylindrical, with a blade diameter of ø 14,3 mm produced according to the dimensional standard NWKa DIN 338. The drill is made of special high speed steel HSS - High Speed Steel. The properties of the steel affect the ability to drill through-hole and blind holes in very hard and hard-to-machine materials such as carbon steels (unalloyed), metals, tool steels, copper, aluminum, bronze, brass and plastics. High-speed steel also significantly improves cutting precision and allows for increased machining efficiency. The drills have 2 central blades with ground edges, which influence the increased durability of the drills. The edges of the drill bits are insensitive to impact and lateral forces. In addition, Drill 14.3 mm is resistant to harsh working conditions and very rarely suffer mechanical damage such as blade breakage, chipping, dulling, chipping. Thus, the tools can be used for a long period of time without having to replace them with new ones. They can be used for conventional drills, milling machines, lathes and CNC machine tools.
