RUKO SPB-DIN338-HSS-TiAlN σπειροειδές τρυπάνι 9,0 mm

The RUKO SPB-DIN338-HSS-TiAlN-Ø9.0mm is a high-performance twist drill bit engineered for demanding drilling tasks. Its TiAlN coating provides exceptional heat resistance, enabling dry machining and extended tool life even at elevated temperatures. The split point geometry ensures precise centering and reduces thrust, while the ground-from-solid HSS body delivers consistent accuracy and durability.

Highlights

• TiAlN coating for superior heat resistance and wear protection
• Split point (cross-ground) for accurate starting without center punch
• DIN 338 standard dimensions: 125 mm total length, 81 mm working length
• Right-hand cutting, cylindrical shank with h8 tolerance
• Suitable for steel, stainless steel, cast iron, non-ferrous metals, and plastics

In daily use

This drill bit excels in high-temperature applications where conventional coatings fail. The TiAlN layer reduces friction and prevents chip adhesion, allowing for smooth drilling in tough materials. The 130° point angle and standard helix flute design ensure efficient chip evacuation and stable cutting performance. Ideal for workshops and industrial environments requiring reliable, long-lasting tooling.
