RUKO SCE-DIN223-M9x1.25mm Round Die, Metric Coarse Thread, HSS, 25 mm OD, 9 mm Thickness, 6g Tolerance

Machinists and metalworkers cutting M9 external threads on bolts, studs, or shafts will reach for the RUKO SCE-DIN223-M9x1.25mm round die. It threads a standard metric coarse pitch of 1.25 mm into general purpose steels, cast iron, and non-ferrous metals, producing a clean 6g tolerance fit.

Why choose it

The ground profile and HSS construction give the die enough hardness and wear resistance for repeated threading jobs, while the 6g tolerance keeps finished threads within the common fit class for general fasteners. The bright, uncoated surface reduces friction during cutting and simplifies cleaning.

Ideal use cases

• Cutting or chasing M9 x 1.25 mm external threads on bolts, studs, and shafts
• Repairing damaged threads on existing fasteners
• Producing custom threaded rods in maintenance and job-shop environments
