RUKO SPB-DIN345-35.5mm-HSS Morse Taper Shank Twist Drill Bit, 35.5 mm, HSS-E Co 5

This RUKO twist drill bit stands out with its Morse taper shank (MT4) for secure, slip-free mounting in machine spindles, making it ideal for heavy-duty drilling in alloyed and unalloyed steels, cast iron, non-ferrous metals, and plastics. Manufactured from HSS-E Co 5 high-speed steel with 5% cobalt, it delivers exceptional heat resistance and wear resistance, even in demanding production environments.

Highlights

• Ground from solid for precise concentricity and accuracy
• Bright surface finish reduces friction and improves chip flow
• Right-hand cutting with a 118° point angle for general-purpose drilling
• DIN 345 standard ensures compatibility with Morse taper tooling
• External coolant supply for efficient heat dissipation

In daily use

With a total length of 315 mm and a flute length of 190 mm, this drill bit provides ample reach for deep-hole applications. The h8 tolerance ensures a consistent hole diameter, while the cobalt alloy maintains hardness at elevated temperatures, extending tool life. Suitable for materials with tensile strength up to 1100 N/mm².
