RUKO SPB-DIN338-HSS-TiN kierrepora 15,5 mm

The RUKO SPB-DIN338-HSS-TiN is a precision twist drill bit with a 15.5 mm diameter, engineered for high-performance drilling in steel, cast iron, non-ferrous metals, and plastics. Its titanium nitride (TiN) coating reduces friction and enhances wear resistance, ensuring efficient chip removal and extended tool life.

Advantages

The TiN coating provides a hard, low-friction surface that improves heat resistance and allows higher cutting speeds. The ground-from-solid HSS body with a 118° point angle and right-hand cutting geometry delivers accurate, clean holes. The cylindrical shank with h8 tolerance ensures secure clamping in standard drill chucks.

Suitable for

• Steel
• Cast iron
• Non-ferrous metals
• Plastics
