Frequently Asked Questions
What is a WIDIA GTD thread forming tap used for?
A WIDIA GTD thread forming tap creates internal threads by displacing material rather than cutting it, producing stronger threads in ductile materials like aluminum, brass, and mild steel. It is ideal for applications requiring chip-free threading, such as automotive and general manufacturing.

The WIDIA GTD 19846 is a 5/16"-18 UNC thread forming tap with H5 / 2B-3B tolerance, plug chamfer, and TiN coated high speed steel. It is designed for general purpose threading in ductile materials, offering wear resistance and consistent thread quality.
