Ø12.75 metal drill bit with a straight shank.
12.75 mm metal drill bit HSS. An advanced twist drill with a smooth straight shank for drilling through and blind holes in metal, unalloyed steels, metal alloys, aluminum, and plastics. The drills offered are manufactured to dimensional standard NWKa DIN 338 from advanced high-alloy HSS high-speed steel. The properties of this steel increase machining productivity, improve cutting accuracy (holes with low surface roughness), and increase resistance to demanding operating conditions. Straight-shank drills of this type resist breakage, cracking, cutting edge chipping, and other damage. They feature special flutes that evacuate chips up the hole, as well as 2 ground cutting edges with strong edges resistant to impact and lateral forces. 12.75 metal drill bit mm is suitable for drilling machines, lathes, milling machines, and computer numerical control machine tools.
