Broca helicoidal RUKO SPB-DIN338 HSS-TiN 8,4 mm

Twist drill bit with titanium nitride coating for efficient drilling in metal and other materials. The 8.4 mm diameter and DIN 338 geometry ensure precise, fast drilling with reduced friction and high heat resistance.

Advantages

The TiN coating lowers friction, allowing higher cutting speeds and longer tool life. The fully ground HSS body provides excellent concentricity and stability. The 118° point angle and right-hand cutting direction deliver clean, accurate holes in a wide range of materials.

Suitable for

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