YG-1 TE704 UNC cold forming taps use oil grooves for machine thread forming. Designed for machine tapping, they form UNC internal threads in ductile workpiece materials. HSS-E construction suits soft materials that achieve at least 8–10% elongation. Pre-drilled holes need larger diameters than those normally used for cutting taps. The range covers #5–40 to 7/16–14 UNC across six listed sizes. DIN 371 applies through 3/8 inch, while the 7/16 inch size uses DIN 376. Its 60° thread profile supports standard UNC coarse-thread applications in production machining. Product family recommendations cover steel, stainless steel, aluminium, copper, bronze and brass materials. This supports applications requiring formed threads in compatible ductile materials.
