RUKO DIN 345 Broca helicoidal HSS con mango cónico Morse 26,0 mm

Drilling large holes in tough materials demands a bit that stays accurate and doesn't slip under load. This RUKO twist drill bit with a Morse taper shank solves that by locking securely into the machine spindle, transferring high torque without a chuck. The 26.0 mm diameter, ground from solid HSS, cuts cleanly through steel, cast iron, and non-ferrous metals.

Who is it for

Machinists, metalworkers, and maintenance technicians who use drilling machines, lathes, or milling machines with an MT3 taper socket and need a reliable, general-purpose drill for large holes.
