RUKO SPB-DIN338-HSS-TiAlN kierreporanterä 8,0 mm

The RUKO SPB-DIN338-HSS-TiAlN-Ø8.0mm is a precision-ground twist drill bit with a TiAlN coating, offering high heat and wear resistance for demanding drilling tasks in steel, cast iron, non-ferrous metals, and plastics. Its 135° self-centering point eliminates the need for center punching, enabling accurate hole positioning from the start.

Highlights

• TiAlN coating for extended tool life and high-temperature performance
• DIN 338 standard with cylindrical shank and h8 tolerance for precise chuck fit
• Self-centering 135° point angle reduces walking and improves accuracy
• Ground from solid HSS for consistent cutting geometry

In daily use

This 8.0 mm drill bit is suitable for general-purpose drilling in workshops and on-site. The right-hand cut and 75 mm flute length provide efficient chip evacuation, while the 117 mm overall length offers good reach. The bronze/gold finish is a visual indicator of the TiAlN coating.
