RUKO SPB-DIN345-35,0mm-HSS morsekartioinen kierteityspora

Engineered for heavy-duty drilling in stationary machines, this RUKO twist drill bit features a 35.0 mm diameter with a Morse Taper Shank (MK4) for secure, high-torque transmission. Its HSS-E construction with 5% cobalt delivers exceptional heat resistance and durability, making it ideal for alloyed and unalloyed steel, cast iron, non-ferrous metals, and plastics.

Highlights

• 35.0 mm diameter with Morse Taper Shank MK4 for stable, high-torque drilling
• HSS-E (High-Speed Steel with 5% Cobalt) for superior heat resistance and long tool life
• Split point (cross-ground) with 130° point angle for precise centering and reduced thrust
• Ground from solid with bright finish and h8 tolerance for high precision
• Right-hand cutting, standard spiral flute for efficient chip evacuation

In daily use

Designed for stationary drilling machines such as pillar drills and lathes, this drill bit excels in demanding industrial applications. The split point geometry ensures accurate hole positioning without center punching, while the cobalt-enriched HSS-E material withstands high temperatures, maintaining cutting performance even in tough materials. Its Morse taper shank provides a self-locking fit in the machine spindle, minimizing slippage during heavy cuts.
