RUKO SPB-DIN338-HSSCo8-TiAlN-Ø9,0mm HSS-Co8 TiAlN-pinnoitettu kierrepora

The RUKO SPB-DIN338-HSSCo8-TiAlN-Ø9.0mm is a fully ground twist drill bit engineered for demanding industrial drilling tasks. Unlike standard HSS bits, its HSS-Co8 cobalt alloy construction and TiAlN coating deliver exceptional heat resistance and wear resistance, making it suitable for high-alloy steels, stainless steel, cast iron, and titanium alloys.

Highlights

• DIN 338 jobber length with 9.0 mm diameter and 125 mm overall length
• TiAlN (Titanium Aluminum Nitride) coating for extended tool life
• 130° split point for self-centering and reduced walking
• Cylindrical shank with h8 tolerance for precise chucking
• Right-hand cutting, fully ground flutes for smooth chip evacuation

In daily use

Professionals will appreciate the split point geometry that eliminates the need for center punching, while the TiAlN coating allows higher cutting speeds and feeds. Coolant is recommended for optimal performance, especially in continuous production environments.
