RUKO SPB-DIN338-HSSCo8-TiAlN-Ø2,5mm kierrepora

Precision-ground from solid HSS-Co 8% cobalt steel with a TiAlN coating, this 2.5 mm twist drill bit withstands temperatures up to 800°C and delivers exceptional wear resistance in demanding materials.

Overview

The RUKO SPB-DIN338-HSSCo8-TiAlN-Ø2.5mm is a high-performance jobber drill bit engineered for tough drilling tasks. It conforms to DIN 338 standards, featuring a cylindrical shank, 130° point angle, and right-hand cutting direction. The TiAlN (Titanium Aluminum Nitride) coating reduces friction and heat buildup, extending tool life even in high-alloy steels, stainless steel, and hardened materials.

What stands out

• 8% cobalt HSS base material for superior hardness and heat resistance
• TiAlN coating enables dry machining and high-speed operation
• Ground from solid for precise geometry and concentricity
• h8 shank tolerance ensures secure chuck gripping
