The RUKO SPB-DIN345-27.0mm-HSS is a precision-ground twist drill bit built for demanding drilling in steel, cast iron, and non-ferrous metals. Its Morse taper shank (MT4) provides a secure, self-locking fit in machine spindles, eliminating slippage under high torque. The polished spiral flutes ensure excellent chip evacuation, while the tapered web core increases rigidity for accurate holes.

Highlights

• High-speed steel (HSS) construction for durability
• Morse taper shank MT4 for direct machine mounting
• 118° point angle for general-purpose drilling
• Bright finish with polished flutes for smooth chip flow
