Drill fi 2.7 with cylindrical shank

Drill 2.7 mm HSS. Modern twist drill, with a cylindrical smooth shank, with a blade diameter ø 2,7 mm produced according to the dimensional standard NWKa, DIN 338. The drill has 2 central blades with ground edges, which affect the strength of the drill. In addition, special spiral grooves allow efficient discharge of chips up the drilled hole. The edges of the drill bits are insensitive to impact and lateral forces. The drill bit is made of special high speed steel HSS - High Speed Steel. Its properties make it possible to drill through-holes and blind holes in very hard and hard-to-machine materials such as unalloyed steels, metals, tool steels, non-ferrous metals, metal alloys and plastics. The high-speed steel also makes it possible to improve drilling accuracy and increase machining efficiency. The drill blades can withstand harsh working conditions and are not subject to mechanical damage such as blade breakage, chipping, dulling, and chipping. Drill the 2.7mm can be used with conventional drills, milling machines, lathes and CNC numerical control machine tools.
