WIDIA GTD Thread Forming Tap: 1/4"-20 UNC, H4 / 3B, Bottoming Chamfer, High Speed Steel (MPN 17242)

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 low-carbon steel. It is ideal for applications requiring high thread strength and no chip evacuation.

The WIDIA GTD 17242 is a 1/4"-20 UNC thread forming tap with H4 / 3B tolerance, bottoming chamfer, and high-speed steel construction. It is designed for general-purpose threading in ductile materials, offering a bottoming chamfer for threading close to the bottom of blind holes.

3G Electric supplies WIDIA GTD thread forming taps worldwide, handling full logistics and customs clearance for global delivery. As a sourcing partner, we provide genuine WIDIA GTD taps like the 17242 model to industrial buyers across multiple sectors.

Select a thread forming tap based on material type, thread size, and hole configuration. For ductile materials like aluminum, use a bottoming chamfer tap for blind holes. Ensure the tap's tolerance class (e.g., H4 / 3B) matches the required thread fit. Always use proper lubrication to reduce friction and extend tool life.
