RUKO SPB-DIN345-HSSCo-Ø22.5mm Morse Taper Shank Drill Bit

Drilling large-diameter holes in tough steels demands a drill bit that stays sharp and stable under high heat and pressure. The RUKO SPB-DIN345-HSSCo-Ø22.5mm Morse Taper Shank Drill Bit solves this with a solid cobalt-alloyed HSS body, precision-ground flutes, and a Morse taper shank that locks securely into the machine spindle for accurate, vibration-free drilling.

Who is it for

Machinists, metalworkers, and maintenance professionals who regularly drill alloyed and unalloyed steels, cast iron, non-ferrous metals, and plastics. It is ideal for use on pillar drills, radial drills, and lathes equipped with an MK2 Morse taper socket.

Main features
