RUKO SPB-DIN338-9,7mm-HSSCo kierrepora

The RUKO SPB-DIN338-9.7mm-HSSCo is a precision twist drill bit engineered for demanding metalworking tasks. Its 5% cobalt alloyed high-speed steel construction delivers exceptional heat resistance and durability, making it a reliable choice for industrial and professional use where standard HSS bits fall short.

Highlights

• Fully ground twist drill bit conforming to DIN 338
• HSS-Co (5% cobalt) for high heat resistance and extended tool life
• 135° split point for accurate self-centering and reduced walking
• Bright surface finish for efficient chip evacuation
• Right-hand cutting direction with cylindrical shank

In daily use

This 9.7 mm drill bit excels in alloyed and unalloyed steel, stainless steel, cast iron, and non-ferrous metals. The 135° point angle penetrates hard materials with less effort, while the fully ground flutes ensure smooth chip removal and cooler cutting. Its h8 shank tolerance guarantees a secure grip in standard drill chucks.
