Ø12.8 metal drill bit with a straight shank.
12.8 mm metal drill bit HSS. High-quality straight-shank twist drill manufactured to NWKa DIN 338 from modern high-alloy high-speed steel (HSS). This type of tool steel enables highly precise drilling and high machining productivity. In addition, the drills are suitable for drilling under very demanding conditions and rarely suffer mechanical damage such as breakage, cracking, or chipping. These excellent cutting properties make the drill suitable for drilling holes in components made of metals, unalloyed (carbon) steels, thermoplastics, non-ferrous metals, and metal alloys. Our drills have 2 central cutting edges and flutes that provide highly effective chip evacuation up the hole. The ground cutting edges withstand impacts and lateral forces. 12.8 metal drill bit mm is suitable for all professional applications.
