RUKO LOS-HSSCo-210mm HSS-Co spiraalboor 8 mm x 210 mm

Twist drill bit made of high-speed steel cobalt (HSS-Co) with a diameter of 8 mm and an overall length of 210 mm. The split point geometry ensures precise centering and reduces walking on the workpiece.

Advantages

The 5% cobalt alloy (M35) provides high heat resistance and wear resistance, enabling drilling in tough materials. The bright finish reduces friction and chip adhesion. The 135° split point allows fast penetration with low pressure.

Suitable for

• Stainless steel
• High-alloy steels
• Cast iron
• Non-ferrous metals
