Ø15.25 metal drill bit with a straight shank
15.25 mm metal drill bit HSS. High-quality twist drill bit with a straight shank, manufactured to the NWKa, DIN 338 dimensional standard. It features strong cutting edges, a 118° point angle, two specially ground cutting edges, and suitable flutes that evacuate chips up the hole. The main advantage of our drill bits is that they are made from advanced HSS (High Speed Steel). This steel offers superior cutting properties. Above all, drill bits made from this steel withstand demanding cutting conditions and resist potential breakage, cracking, chipping, edge fracture, and other mechanical damage. They also enable high-speed drilling, which generates high temperatures. 15.25 metal drill bit mm is suitable for machining unalloyed steels, metals, metal alloys, copper, aluminum, and plastics. They can be used on conventional drilling machines, milling machines, lathes, and computer numerically controlled CNC machine tools.
