RUKO SPB-DIN338-HSSCo8-Ø8,4mm kierrepora HSS-Co 8% DIN 338

Twist drill bit with 8.4 mm diameter, manufactured from high-speed steel with 8% cobalt content for high heat and wear resistance. Ground from solid to DIN 338 standard with a 130° point angle for precise centering and efficient cutting in tough materials.

Advantages

High cobalt content provides superior hardness and heat resistance, enabling drilling in high-strength steels up to 1100 N/mm². The bright/steam tempered surface reduces friction and improves chip evacuation. Cylindrical shank with h8 tolerance ensures secure clamping and concentric running.

Suitable for

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