RUKO SPB-DIN338-HSSCo8-Ø1.0mm HSS-Co8 Twist Drill Bit DIN 338

This RUKO twist drill bit stands out with its 8% cobalt alloyed high-speed steel, delivering high heat and wear resistance for demanding metal drilling. The split point geometry and 135° point angle ensure precise centering and reduced thrust, making it ideal for stainless and acid-resistant steels.

Highlights

• HSS-Co 8% cobalt alloy for high heat resistance
• Split point (cross ground) for accurate starting without center punch
• 135° point angle for efficient cutting in hard materials
• Fully ground flutes for smooth chip evacuation
• DIN 338 standard with cylindrical shank

In daily use

With a diameter of 1.0 mm and a total length of 34 mm, this drill bit is suited for precision work in high-alloy steels, stainless steel, cast iron, and plastics. The bright finish reduces friction, while the h8 tolerance ensures consistent hole quality.
