Punta elicoidale RUKO SPB-DIN338-HSS-G-Kreuz-19/64

Precision drilling in tough materials demands a bit that stays sharp and centered. The RUKO SPB-DIN338-HSS-G-Kreuz-19/64 twist drill bit solves that with a split point tip that prevents walking and a ground HSS body that cuts cleanly through steel, cast iron, and more.
