RUKO DOB-HSS-6,5mm-blank spiraalboor

Precision drilling in metal and hard plastics demands a bit that stays sharp, centers accurately, and resists wandering. The RUKO DOB-HSS-6.5mm-blank twist drill bit solves this with a ground-from-solid HSS body and a 135° split point that bites instantly without a center punch.

Who is it for
