RUKO SPB-TX-DIN338-HSSCo-Ø8,0mm spiraalboor

Precision-ground HSS-Co twist drill bit with 5% cobalt for high heat resistance and long life in tough materials. The 135° split point eliminates walking and reduces thrust, while the DIN 338 standard ensures consistent geometry for professional results.

Overview

The RUKO SPB-TX-DIN338-HSSCo-Ø8,0mm is a high-performance twist drill bit made from HSS-Co steel with 5% cobalt content. This cobalt alloy significantly increases red hardness, allowing the bit to maintain its cutting edge at high temperatures generated during drilling in hard steels and stainless steels. The bright finish reduces friction and improves chip evacuation.
