Item # 64986, 1 3/8-4 2G TANDEM ACME 4FL PLUG On Tapco Cutting Tools Inc.

Tandem Style ACME Tap Application
Tandem Acme taps combine an initial roughing cut with a final finishing cut, in one pass.
The roughing section of the tap has a thread with a sharper angle which permits threads to be relieved more effectively and eliminates the wide, flat Acme crest. This results in free-cutting characteristics which makes greater stock removal possible.
The last few threads on the roughing section act as a guide for the short finishing section, which corrects the angles and brings the thread to size.
Buttress, Modified Square, Stub Acmes and Metric Trapezoidal taps available by requesting a quote.
