WIDIA GTD Three-Piece Hand Tap Set

This three-piece hand tap set is used for cutting 1"-8 UNC internal threads in metal. It includes taper, plug, and bottoming taps for progressive threading in through-holes and blind holes. Common applications include automotive, heavy equipment, and general manufacturing where high-strength threads are required.

The kit includes three high-speed steel taps: a taper tap (4GZ71), a plug tap (1C925), and a bottoming tap (1C927). Each tap has a 1"-8 UNC thread size, H4 tolerance, and 4 flutes. The set is designed for hand threading operations in ferrous and non-ferrous materials.

Start with the taper tap for initial threading, then use the plug tap to deepen threads, and finish with the bottoming tap for threads close to the hole bottom. For through-holes, the taper and plug taps are usually sufficient. Always use cutting fluid and align the tap perpendicular to the workpiece.
