RUKO SPB-TL3000 HSS-G Twist Drill Bit 8.5 mm DIN 338

The RUKO SPB-TL3000 8.5 mm twist drill bit stands out for its fully ground HSS-G construction, delivering clean, accurate holes in a wide range of materials. Unlike standard rolled bits, its precision-ground flutes and 118° point angle reduce walking and improve chip evacuation, making it a reliable choice for both professional and demanding DIY tasks.

Highlights

• Fully ground HSS-G for high cutting performance and durability
• DIN 338 standard dimensions ensure compatibility with standard drill chucks
• Right-hand cutting with 118° point angle for efficient drilling
• Bright finish for corrosion resistance and smooth chip flow
• h8 shank tolerance for precise fit in keyless and keyed chucks

In daily use

This drill bit excels in steel, cast iron, non-ferrous metals, plastics, and wood. Its 75 mm working length provides ample depth for most through-hole and blind-hole operations, while the cylindrical shank ensures secure clamping. The fully ground flutes reduce friction and heat build-up, extending tool life and improving hole quality.
