RUKO SCE-DIN223-M33x3.5mm Round Die, HSS, Metric Coarse Thread

Cutting external metric threads by hand demands a die that stays sharp and accurate across many workpieces. The RUKO SCE-DIN223-M33x3.5mm round die is ground from high speed steel to produce clean, precise M33 coarse threads in unalloyed and low-alloyed steels, non-ferrous metals, and plastics.

Who is it for

Machinists, maintenance technicians, and metalworkers who need a durable, right-hand cutting die for manual or machine threading operations. It fits standard round die holders for secure mounting.
