Tapping
The torque of CCW is 1.4 times of the torque of CW to prevent the problem of the swarf. The tap can be clamped with one touch operation. The adjustment mechanism of the setting torque is not installed on the ZKG tap collet. The high torque setting type is available for the tapping on the stainless as an option. e.g ZKG12-4-HT
