Ø18.75 metal drill bit with a straight shank
18.75 mm metal drill bit HSS. High-grade straight-shank twist drill bit for drilling through holes and blind holes in P1.2 P1.3 class materials (metals, metal alloys, unalloyed steels, nonferrous metals). The drill bits feature 2 central cutting edges, a 118° point angle, specially ground cutting edges, and helical flutes for efficient chip evacuation up the hole. Our NWKa drill bits are made from advanced HSS high-speed steel. Its superior cutting properties significantly increase drilling efficiency and improve hole accuracy. The drill bits also withstand demanding cutting conditions, and their cutting edges resist mechanical damage (breakage, cracking, chipping, edge fracture). Metal drill bits with a diameter of 18.75 mm also offer greater hardness and wear resistance at the high temperatures generated during high-speed drilling. Recommended for conventional and computer-controlled CNC machine tools.
