RUKO SPB-DIN338-HSSCo8-TiAlN-Ø8,1mm spiraalboor

Twist drill bit with 8.1 mm diameter, engineered for high-performance drilling in demanding materials. The TiAlN coating combined with HSS-Co 8% cobalt steel delivers exceptional heat resistance up to 600°C and extended tool life.

Advantages

Split point geometry ensures precise centering and reduces thrust, while the 135° point angle provides excellent cutting performance. The TiAlN coating reduces friction and prevents built-up edge, making it ideal for stainless and acid-resistant steels.

Suitable for

• High-alloy steels
• Stainless steel
• Acid-resistant steels
• Cast iron
• Bronze
• Titanium alloys
