RUKO SPB-DIN338 10,0mm broca helicoidal HSS-Co

Twist drill bit with 10.0 mm diameter, precision ground from solid HSS-Co (M35) for high heat resistance. Self-centering split point and Type N flute ensure accurate drilling in alloyed and unalloyed steel, stainless steel, cast iron, and non-ferrous metals.

Advantages

High cobalt content (5%) provides superior hardness and heat resistance. Split point geometry reduces walking and enables precise hole positioning. Bright/vapourised surface treatment improves chip evacuation and reduces friction.

Suitable for

• Alloyed and unalloyed steel
• Stainless steel
• Cast iron
• Non-ferrous metals
