With the Phantom 11.710 hss twist drill bit, you drill clean and accurate holes in non-ferrous metals such as aluminium and copper. The specialized flute geometry and 130° point angle prevent long, ductile chips from clogging the flutes, ensuring smooth chip evacuation without excessive heat build-up. This allows you to produce precise 8 mm diameter holes in sheet metal and aluminium profiles. Manufactured to the din 338 standard, it features an overall length of 117 mm and a working flute length of 75 mm. The 8 mm cylindrical shank secures easily into any standard drill chuck on drill presses or handheld drills.
