Escareador RUKO FLS-DIN373-furo central-M10-MK2, M10, cone Morse 2, HSS

Creating precise counterbores for cylindrical-head screws in metal is a challenge without the right tool. The RUKO FLS-DIN373-Kernloch-M10-MK2 counterbore solves this by delivering clean, accurate recesses for M10 screws with cylindrical heads, such as hexagon socket head cap screws. Manufactured to DIN 373, it ensures compatibility with standard screw dimensions and provides reliable performance in steel, cast iron, and non-ferrous metals.

Who is it for

This counterbore is ideal for machinists, metalworkers, and maintenance professionals who need to produce counterbores with a Morse Taper 2 shank. It fits directly into drilling machines or lathes with an MK2 spindle, eliminating the need for additional adapters.
