RUKO SPB-DIN338-13/32-HSSCo kobaltový špirálový vrták 10,3 mm DIN 338

This RUKO twist drill bit stands out through its 5% cobalt-alloyed high-speed steel and 135° split point, which centres itself on contact and reduces walking on hard steels. The fully ground flutes and h8 shank tolerance deliver precise holes in demanding materials.

Highlights

• DIN 338 twist drill bit with 13/32 inch (10.3 mm) diameter
• HSS Co 5 steel withstands tensile strengths up to 1100 N/mm²
• 135° split point for self-centering and reduced thrust
• Right-hand cutting, bright polished finish
• Cylindrical shank with h8 tolerance

In daily use

The cobalt content keeps the cutting edges hard even at elevated temperatures, making this bit suitable for stainless and alloyed steels, cast iron, non-ferrous metals and plastics. The 87 mm working length and 133 mm total length provide good reach for most workshop tasks.
