11.25 mm metal drill bit HSS. Professional straight-shank twist drill manufactured to the dimensional standard NWKa, DIN 338. This drill has a diameter of 11.25 mm and is designed for machining very hard and difficult-to-machine materials. It can drill through holes and blind holes in components made of unalloyed steel, metals, nonferrous metals and metal alloys. We offer straight-shank drills for professional applications using drilling machines, milling machines, lathes and CNC (computer numerical control) machine tools. 11.25 metal drill bit mm is a solid drill made of high-grade high-speed steel HSS. This steel makes the tools more productive, more resistant to demanding cutting conditions, and resistant to breakage, cracking, chipping and other mechanical damage. NWKa drills also significantly reduce machining time, allowing better utilization of existing machine tools.
