RUKO SCE-DIN223-1-7/8x4,5-BSW cossinetes de roscar, 1-7/8 polegadas BSW, 4,5 TPI, HSS

Cutting external threads by hand or machine in tough materials often means dies that dull quickly or produce rough, inaccurate threads. The RUKO SCE-DIN223-1-7/8x4,5-BSW threading die solves this with high-speed steel (HSS) construction and a ground thread profile for clean, precise BSW threads.
