Escareador RUKO FLS-DIN373-média-M14-MK2 DIN 373 M14 cone Morse 2 HSS-G

Counterboring for cylindrical head screws can be challenging without the right tool. This RUKO counterbore solves that by precisely machining flat-bottom recesses for M14 screws, ensuring a clean, professional finish in steel, cast iron, and non-ferrous metals.

Who is it for

Machinists, metalworkers, and maintenance technicians who need to create accurate counterbores for DIN 974-1 cylindrical head screws in medium to large workpieces.
