RUKO SPB-DIN338-HSS-TiAlN Ø12,5mm σπειροειδές τρυπάνι

The RUKO SPB-DIN338-HSS-TiAlN Ø12.5mm twist drill bit combines a fully ground HSS body with a TiAlN coating, delivering high wear resistance and heat resistance up to 800°C. Its split point geometry provides self-centering for accurate hole positioning without a center punch.

Highlights

• TiAlN coating for extended tool life and high-temperature performance
• Split point tip for fast, precise drilling without walking
• DIN 338 jobber length for versatile use in hand drills and machines
• Suitable for steel, stainless steel, cast iron, non-ferrous metals, and plastics

In daily use

This drill bit excels in general-purpose industrial drilling. The 135° point angle and self-centering split point reduce thrust requirements and improve hole quality. The TiAlN coating reduces friction and allows drilling in tough materials without coolant in many cases.
