Frequently Asked Questions

What is a WIDIA GTD left-hand tap kit used for?

This WIDIA GTD tap kit is used for cutting left-hand internal threads in metal parts. It is ideal for maintenance, repair, and production applications where reverse-thread fasteners are required, such as in automotive, aerospace, and general machining industries.

What are the specifications of the WIDIA GTD 14029 tap kit?

The WIDIA GTD 14029 kit includes three high-speed steel taps: taper (3FMJ8), plug (3FMJ7), and bottoming (3FMJ9). It is a left-hand, 4-flute set for 1/4"-20 UNC threads with an H3 tolerance. Each tap is designed for manual or machine threading.

How to select the correct tap from a WIDIA GTD three-piece set?

Use the taper tap (3FMJ8) first to start threads, then the plug tap (3FMJ7) to deepen them, and finally the bottoming tap (3FMJ9) to thread to the bottom of a blind hole. Always match the tap to the material and use cutting fluid for best results.
