RUKO SPB-TX-DIN338-HSSCo-Ø10,2mm špirálový vrták

The RUKO SPB-TX-DIN338-HSSCo-Ø10.2mm twist drill bit sets itself apart with a 5% cobalt alloyed high-speed steel body and a cross-ground split point, delivering accurate starts and reduced wandering in tough materials. Its fully ground flutes and 135° point angle are built for efficient chip removal and lower cutting forces, making it a dependable choice for demanding drilling tasks.

Highlights

• DIN 338 standard twist drill bit with cylindrical shank
• HSS-Co (5% cobalt) for high heat resistance and durability
• Cross-ground point (split point) for precise centering
• Right-hand cutting, bright finish, fully ground
• Suitable for alloyed and unalloyed steel, stainless steel, cast iron, and non-ferrous metals up to 1100 N/mm²

In daily use

This drill bit is a workhorse for workshop and industrial applications. The cobalt content maintains hardness at elevated temperatures, while the split point reduces thrust and prevents walking on smooth surfaces. The h8 tolerance ensures consistent hole diameters, and the bright finish aids chip flow in a wide range of metals.
