How to select the correct WIDIA GTD tap for a job?

Select a WIDIA GTD tap based on thread size, tolerance class, chamfer type, and material. For blind holes, use a bottoming chamfer spiral flute tap like the VTSFT5138. Match the H3 / 3B tolerance to your required thread fit. Always verify the tap's coating and flute count suit your workpiece material.
