RUKO SPB-DIN338-HSS-TiN-Ø8,8mm Broca helicoidal

This RUKO twist drill bit stands out with its titanium nitride (TiN) coating, which reduces friction and increases wear resistance for longer tool life. The 8.8 mm diameter and DIN 338 geometry make it a reliable choice for general-purpose drilling in steel, alloyed steel, cast iron, non-ferrous metals, and plastics.

Highlights

• TiN coating for reduced friction and extended service life
• Precision-ground HSS body with 118° point angle for accurate starts
• Right-hand cutting, cylindrical shank fits standard drill chucks
• DIN 338 dimensions: 125 mm total length, 81 mm working length

In daily use

The golden TiN surface not only looks distinctive but also helps chips slide away smoothly, reducing heat build-up.
