RUKO LOS-HSSCo-55mm σπειροειδές τρυπάνι HSS-Co5 5,5 mm

Twist drill bit with 5% cobalt high-speed steel for drilling in high-alloy steels, stainless steel, acid-resistant steels, heat-resistant steels, cast iron, non-ferrous metals, and plastics. The split point provides self-centering and reduces walking, while the bronze finish improves chip flow and wear resistance.

Advantages

Fully ground from HSS-Co5 for high heat resistance and excellent wear resistance. The 135° split point eliminates center punching and ensures accurate hole positioning. Steam tempered bronze finish reduces friction and extends tool life.

Suitable for

• High-alloy steels
• Stainless steel
• Acid-resistant steels
• Heat-resistant steels
• Cast iron
• Non-ferrous metals
• Plastics
