RUKO SPB-DIN345-HSSCo Ø27,0 mm morsekartio-kierrepora

When you need to drill precise, large-diameter holes in tough steel or cast iron, a standard twist drill often lacks the rigidity and torque transfer required. The RUKO SPB-DIN345-HSSCo-Ø27.0mm solves this with a Morse taper shank that seats firmly in the machine spindle, preventing slippage under heavy load. Its cobalt-alloyed high-speed steel withstands high temperatures, keeping the cutting edge sharp longer.

Main features

• Morse taper shank (MT3) for secure, self-locking fit in drill presses and lathes
• HSS-Co 5% cobalt steel: superior heat resistance and wear life
• Ground from solid with bright finish for precise concentricity and smooth chip flow
• DIN 345 standard geometry with 130° point angle for general metal drilling
• Diameter tolerance h8 for accurate hole sizing

Tips

Use a suitable cutting fluid when drilling steel to extend tool life. Ensure the Morse taper socket is clean and free of burrs before inserting the drill. For deep holes, retract the drill periodically to clear chips.
