RUKO SPB-DIN338-HSS-TiAlN punta elicoidale 3,0 mm

Precision-ground 3.0 mm twist drill bit with TiAlN coating for high-performance drilling in steel, stainless steel, and cast iron.

Overview

The RUKO SPB-DIN338-HSS-TiAlN is a jobber-length twist drill bit manufactured from high-speed steel and coated with titanium aluminum nitride (TiAlN). The TiAlN coating provides excellent heat and wear resistance, extending tool life and enabling higher cutting speeds. The split point tip (135°) reduces walking and requires less thrust, while the fully ground flutes ensure efficient chip evacuation.

What stands out

• TiAlN coating for superior heat resistance and durability
• Split point geometry for accurate starting without center punch
• Fully ground from solid HSS for consistent quality
• DIN 338 jobber length for general-purpose applications
