MEGA SYNCHRO TAPPING HOLDER OVERVIEW
BIG MEGA SYNCHRO tapping holder compensates for synchronization errors with any type of tap. Minimized thrust load to both the tap and workpiece improves thread quality and tap life.

BIG MEGA SYNCHRO
Approx. 13.2 lbs
BIG MEGA SYNCHRO reduces load to approx. 13.2 lbs. This is less than 1/10th of the load compared to a collet chuck.
SPIRAL TAP AU:1/4-20, N=1,000 RPM
-180 -160 -135 -110
Approx. 165 lbs. of reversal load is applied to a tap held with a collet chuck.
Spiral grooves on spiral tap cause loading in the reverse direction, similar to an end mill. • Measured by Kistler Dynamometer

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 the cutting load. Fine surface finish of threads is achieved.
