RUKO SPB-DIN338-HSSCo8-Ø2,2mm kierrepora

The RUKO SPB-DIN338-HSSCo8 twist drill bit stands out for its solid cobalt-alloyed high-speed steel construction, ground from solid for precise, wear-resistant cutting edges. With a 2.2 mm diameter and DIN 338 geometry, it delivers accurate holes in demanding materials.

Highlights

• HSS-Co8 material with 8% cobalt for high heat and wear resistance
• Ground from solid for superior concentricity and edge retention
• 135° point angle for reduced wandering and faster cutting
• h8 tolerance for consistent hole quality

In daily use
