compensates for synchronization error. Synchronization errors still exist with rigi tapping. A small gap is cause by the timing uring the change between forwar an reverse spinle rotation an the fee irection from minus to plus. In aition, pitch tolerances on the tap also cause error. Some taps have stronger cutting resistance epening on the shape. BIG Mega Synchro compensates for synchronization errors with any type of tap. Minimize thrust loa to both the tap an workpiece improves threa quality an tap life. oa to Tap Measure by Kistler ynamometer Spiral Tap AU1/4-20 N=1,000 RPM Twiste grooves on a spiral tap cause loaing in the reverse irection, similar to an en mill.

However, BIG Mega Synchro minimizes thrust loas in both irections. Thrust loa in the forwar irection is continuously applie to a roll tap, reaching its peak at the moment when rotation is change to reverse. BIG Mega Synchro eliminates the loa effectively. 3
