RUKO KEB-HSS-Mod.55-12,0 mm spiraalboor, HSS, DIN 338, 151 mm lengte

Precision drilling in steel, cast iron, non-ferrous metals, and plastics requires a bit that stays sharp and cuts cleanly without wandering. The RUKO KEB-HSS-Mod.55-12.0 mm twist drill bit solves this with a ground-from-solid HSS body, a 118° conical point, and a bright finish that reduces friction and heat build-up.

Who is it for
