RUKO SPB-DIN345-43.0mm HSS Morse Taper Drill Bit

The RUKO SPB-DIN345-43.0mm-HSS is a morse taper drill bit engineered for heavy-duty drilling in tough materials. Unlike standard twist drills, it features a robust Morse taper shank (MK 5) that provides secure, self-locking engagement in machine spindles, ensuring maximum torque transfer and minimal slippage during demanding operations.

Highlights

• Precision ground from solid HSS-E Co 5 for exceptional hardness and wear resistance
• 43.0 mm diameter with DIN 345 standard geometry for reliable, accurate holes
• Morse taper shank MK 5 for stable, high-torque machine drilling
• 118° point angle optimised for general-purpose drilling in steel and cast iron

In daily use

This drill bit is built for industrial applications where reliability is critical. The 5% cobalt alloy maintains cutting performance at elevated temperatures, allowing continuous drilling without premature dulling. Its bright finish reduces friction and chip adhesion, promoting smoother chip evacuation and longer tool life. The long flute length (190 mm) supports deep-hole drilling while the overall length of 315 mm provides ample reach.
