RUKO SPB-DIN338-10,3mm-HSSCo spiraalboor

Twist drill bit with 10.3 mm diameter, manufactured from high-speed steel with 5% cobalt for high heat resistance and wear resistance. The 135° split point provides self-centering and reduces thrust, enabling precise drilling in tough metals.

Advantages

Fully ground from HSS-Co with 5% cobalt, this drill bit withstands high temperatures and maintains hardness, extending tool life. The split point geometry ensures accurate starts without center punching, while the bright finish reduces friction and improves chip evacuation.
