RUKO SPB-DIN338-HSS-TiN Ø8,0 mm kierreporanterä

The RUKO SPB-DIN338-HSS-TiN Ø8.0 mm twist drill bit is a precision-ground tool with a titanium nitride coating that reduces friction and increases heat resistance up to 600°C. Unlike standard uncoated bits, the TiN layer extends service life and improves chip evacuation in alloyed and unalloyed steel, cast iron, non-ferrous metals, and plastics.

Highlights

• DIN 338 standard geometry with 118° point angle and right-hand cutting direction
• Ground from solid HSS for consistent accuracy and durability
• Cylindrical shank with h8 tolerance fits standard drill chucks
• Gold TiN coating for wear resistance and reduced cutting torque

In daily use

The 8.0 mm diameter and 75 mm working length make this bit suitable for general-purpose drilling in workshops and on-site. The TiN surface helps prevent material build-up on the cutting edges, especially when drilling steel or cast iron. The 117 mm overall length provides good reach for most hand-held and pillar drills.
