Broca helicoidal RUKO SPB-DIN338-HSSCo8-TiAlN-Ø6,7mm

Precision-ground from solid HSS-Co 8% with a TiAlN coating, this twist drill bit delivers exceptional heat resistance and durability in demanding materials. The 135° split point design eliminates walking and reduces thrust pressure, ensuring accurate hole placement without center punching.

Highlights

• DIN 338 standard with h8 tolerance for consistent performance
• TiAlN coating provides very high heat resistance, ideal for high-alloy steels, stainless steels, heat-resistant steels, titanium alloys, and cast iron
• Split point (self-centering) geometry for precise starts and reduced drilling force
• High core strength and excellent chip removal for efficient drilling
• Right-hand cutting direction, suitable for a wide range of industrial applications

In daily use

With a working length of 69 mm and overall length of 109 mm, this 6.7 mm drill bit offers a balanced combination of reach and stability. The cylindrical shank ensures secure clamping in standard drill chucks, while the bronze/black finish from the TiAlN coating reduces friction and extends tool life.
