RUKO SPB-DIN338-9.25mm-HSSCo Broca helicoidal, 9,25 mm, DIN 338, HSS-Co 5% cobalto, 125 mm comprimento, afiação de ponta 135°

Twist drill bit with 9.25 mm diameter, manufactured to DIN 338 from HSS-Co high-speed steel with 5% cobalt content. The split point geometry and 135° point angle provide precise centering and reduced thrust, making it suitable for drilling tough and hard materials. Precision ground with a bright finish and h8 tolerance for consistent performance.

Advantages

High cobalt content (5%) delivers very high heat resistance and wear resistance, extending tool life in demanding applications. Split point design minimizes walking and improves hole accuracy, while the cylindrical shank ensures secure clamping in standard drill chucks.

Suitable for

• Alloyed and unalloyed steel
• Stainless steel
