RUKO SPB-DIN345 29,0mm HSS-E špirálový vrták s kužeľovou stopkou MT3

The RUKO SPB-DIN345 29.0mm HSS-E twist drill bit is engineered for demanding drilling in high-alloy steels, stainless steels, heat-resistant steels, and cast iron up to 1000 N/mm² tensile strength. Its cobalt-alloyed high-speed steel and ground-from-solid construction deliver exceptional durability and precision, while the Morse taper shank (MT3) ensures secure, concentric mounting in machine spindles.

Highlights

• 29.0 mm drill diameter with h8 tolerance for accurate holes
• Morse taper shank MT3 for direct fit in drill presses and lathes
• HSS-E (cobalt alloyed) for high heat and wear resistance
• 130° point angle optimized for tough materials
• Bright finish for smooth chip evacuation

In daily use

This twist drill bit is intended for stationary drilling machines with Morse taper spindle. The 190 mm cutting length and 315 mm total length provide ample reach for deep holes. The right-hand cutting direction suits standard spindle rotation. Use appropriate cutting fluid to extend tool life when drilling stainless or heat-resistant alloys.
