That is why helpful sizing charts of tap drills are created for that. The drill bit size for 10-32 taps is entirely different because they come in two different thread counts. The fractional drill bit measurement is 5/32. These include aluminum, copper, brass, zinc, low carbon steels, and free machining stainless steels. Special Taps Contact H-Limits In addition to the nominal size and pitch of tap, there is another important dimensional factor to be considered in selecting a ground thread tap for a given job. The correct drill bit size for 10-32 tap is a 21 drill bit. Unified threads are defined with an A (external) or B (internal). Thread Calculator and Chart for metric thread, npt thread, bsp thread, unf thread, unc thread, acme thread, bspp thread, un thread, bspt thread, pipe thread, stub acme thread and buttress thread. Thread forming taps (sometimes called cold forming taps) are designed for cold forming threads in ductile materials. HOME TAP-DRILL SIZE CALCULATOR To minimize tapping problems and lengthen tool life, use the largest drill possible to produce a minor diameter that will result in the lowest percentage of full thread consistent with adequate strength. Thread Limits (H & D): Chamfer Styles: Class of Fit is the standard identification system describing the tolerance and closeness of fit between the threaded hole and the tap.
