RUKO SPB-DIN345-47,5mm broca helicoidal HSS con cono Morse

Twist drill bit with Morse taper shank for large-diameter drilling in tough materials. The 5% cobalt HSS-E construction delivers high heat resistance and hardness, making it suitable for continuous use in steel and cast iron.

Advantages

Fully ground from HSS-E with 5% cobalt for superior wear resistance. The Morse taper shank (MT5) ensures secure torque transmission and precise centering in machine spindles. Tapered web design increases rigidity and reduces deflection during deep drilling.
