Ø11.7 metal drill bit with a straight shank
11.7 mm metal drill bit HSS. Modern NWKa drill with a plain straight shank, compliant with DIN 338. Designed for drilling through and blind holes in components made of unalloyed steel, metal, tool steel, non-ferrous metals, metal alloys, and plastics. 11.7 metal drill bit mm is of solid construction, meaning it is made entirely of high-alloy high-speed steel (HSS). The properties of this steel improve drilling accuracy and productivity. These drills also better withstand demanding operating conditions, even at high temperatures up to 600°C. They also offer increased resistance to changing operating conditions, including thermal shock. They resist breakage, cracking, and other mechanical damage. The drills are designed for machine drilling using professional CNC machine tools as well as conventional drilling machines, lathes, and milling machines.
