Broca helicoidal HSS-E RUKO SPB-DIN345 34,0 mm com haste de cone Morse

Twist drill bit with Morse taper shank for large-diameter drilling in steel and cast iron. The 34.0 mm HSS-E (cobalt alloyed high-speed steel) body withstands high thermal loads, while the fully ground flutes ensure precise chip removal and accurate holes.

Advantages

• HSS-E with cobalt for high heat resistance and long tool life
• Morse taper shank (MT4) provides secure torque transmission in machine spindles
• Fully ground flutes for excellent concentricity and surface finish
• Bright finish reduces friction and improves chip flow
• DIN 345 standard geometry for reliable performance in tough materials

Suitable for

• Steel and cast steel up to 900 N/mm²
• Alloyed and non-alloyed materials
• Grey cast iron
• Non-ferrous metals
• Plastics
