Load to tap
* Measured by Kistler dynamometer
Spiral grooves on spiral tap cause loading in the reverse direction, similar to an end mill.

Comparison of surface finish
Tapping of exotic materials tends to cause a compressed burr on the thread surface. BIG MEGA SYNCHRO compensates for synchronization errors and minimizes cutting load. Fine surface finish of threads is achieved.

Compensation for synchronization error eliminates heavy thrust load of large diameter tapping.
