WIDIA GTD Thread Forming Tap: #8-32 UNC, H3 / 3B, Bottoming Chamfer

A WIDIA GTD thread forming tap creates internal threads by displacing material rather than cutting it, producing stronger threads in ductile materials like aluminum and steel. It is ideal for high-speed production environments where chip evacuation is a concern.

This WIDIA GTD tap is #8-32 UNC with a H3 / 3B tolerance class, bottoming chamfer, and TiN coated high speed steel. It is designed for through or blind holes and provides a 3B fit for precision threading applications.

3G Electric supplies WIDIA GTD taps worldwide, handling full logistics and customs clearance. As a global industrial sourcing partner, we provide genuine WIDIA GTD thread forming taps like the #8-32 UNC model (MPN 19857) to customers across 14 industrial departments.

Select a thread forming tap based on material type, thread size, and hole configuration. For ductile materials like aluminum or low-carbon steel, use a bottoming chamfer tap for blind holes. Ensure the tap's tolerance class (e.g., H3) matches your required thread fit.
