RUKO SPB-DIN338-HSSCo8-TiAlN-Ø7,0mm σπειροειδές τρυπάνι

Twist drill bit with 7.0 mm diameter, engineered for high-performance drilling in tough materials. The TiAlN coating and HSS-Co8 cobalt steel deliver exceptional heat and wear resistance, ensuring long tool life even in hardened steels up to 1100 N/mm².

Advantages

Fully ground from HSS-Co8 with 8% cobalt, this drill bit offers superior hardness and toughness. The TiAlN coating reduces friction and allows higher cutting speeds, while the 130° point angle provides excellent centering and reduced thrust. Right-hand cutting with a cylindrical shank ensures compatibility with standard drill chucks.

Suitable for

• High-alloy steels
• Stainless steel
• Cast iron
• Titanium alloys
• Heat-resistant steels
• Hardened materials
