These taps combine the initial roughing cut with the final finishing cut, in one pass, to achieve an acme screw thread. Since acme thread pitches are generally coarse relative to diameters, these taps are subjected to heavy chip loads. To achieve a high quality acme thread in a cost-effective manner, roughing and finishing operations are recommended.
