Programming AccuThread ® T3

AccuThread T3 is designed to cut minimal threads at a time to reduce side deflection in hard or difficult-to-machine materials.

To improve rigidity, they are intended to be programmed to cut each thread starting at the top and progressing down in Z-axis. Because right hand threads are most common, AccuThread T3 thread mills are left hand cutting (M04) to maintain the climb milling method.
