Vermont American 1-3/8-6 4-Flute HHS Bright Tap Set

The Vermont American 1-3/8-6 4-Flute HSS Bright Tap Set is a precision hand tap kit engineered to cut and repair 1-3/8"-6 internal threads in metalworking projects. It includes taper, plug, and bottoming taps—all made from high-speed steel with a bright finish—and its 4-flute design aids faster cutting and predictable chip flow. The taps are right-hand threads, Unified Inch Thread, and designed for internal thread cutting and repair in both manual and machine-assisted applications, suitable for through-hole and blind-hole work. This set is commonly used in machine shops, maintenance departments, fabrication facilities, automotive repair, heavy equipment servicing, and industrial manufacturing where accurate threading is required.
