RUKO DIN 338 HSS TiN-gecoate spiraalboor 6,8 mm

Twist drill bit with a 6.8 mm diameter, precision-ground from high-speed steel and finished with a titanium nitride coating for high wear resistance and heat resistance. The TiN coating reduces friction and extends tool life when drilling in steel, cast iron, non-ferrous metals, and plastics.

Advantages

The TiN coating provides a hard, low-friction surface that improves chip evacuation and allows higher cutting speeds. The 118° point angle and spiral flute design ensure accurate centering and efficient material removal.

Suitable for

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