Broca helicoidal RUKO SPB-DIN338-HSSCo8-Ø8,9mm HSS-Co 8% cobalto

Twist drill bit made from high-speed steel with 8% cobalt for exceptional heat and wear resistance. The split point design ensures precise centering and reduced thrust, making it ideal for drilling stainless steel, high-alloy steel, and cast iron.

Advantages

Fully ground from HSS-Co 8% for very high heat resistance and wear resistance. The 135° split point prevents walking and provides fast, accurate starts without center punching. Bright surface finish reduces friction and improves chip evacuation.
