To select the correct WIDIA GTD Thread Forming Tap, match the thread size (e.g., 5/16"-18 UNC) and tolerance class (H5 for 2B-3B) to your hole requirements. Choose a bottoming chamfer for blind holes or a plug chamfer for through holes. Ensure the tap is suitable for the workpiece material—forming taps work best in ductile metals like aluminum or low-carbon steel.
