RUKO DIN 345 Morse Taper Shank Twist Drill Bit 50.0 mm HSS

Large-diameter drilling in tough materials demands a tool that stays centered, cuts cleanly, and withstands heavy loads. The RUKO DIN 345 Morse Taper Shank Twist Drill Bit delivers that with a 50.0 mm diameter and robust HSS construction. Its Morse Taper Shank (MT5) locks securely into machine spindles, preventing slippage during high-torque operations.

Who is it for

Machinists, metalworkers, and maintenance professionals who need reliable, large-hole drilling in steel, cast iron, non-ferrous metals, and plastics. Ideal for use in drill presses, lathes, and milling machines equipped with an MT5 spindle.
