RUKO SCE-DIN223-1-3/8x6-BSW Round Threading Die, 1 3/8 inch BSW, 6 TPI, HSS, DIN 223

Cutting external threads in large-diameter British Standard Whitworth fasteners requires a die that holds its edge and stays true to the thread form. The RUKO SCE-DIN223-1-3/8x6-BSW round threading die is made from high-speed steel and precision ground to DIN 223, so it produces clean, accurate 1 3/8 inch BSW threads with 6 threads per inch in unalloyed and low-alloy steels and non-ferrous metals.

Who is it for

Maintenance technicians, mechanical engineers, and metalworking professionals who need to cut or restore coarse Whitworth threads on large bolts, shafts, or pipe fittings. It fits any standard 75 mm die stock.
