• MEGA MICRO NUT is included; coolant pipe, collet and wrench must be ordered separately • Please note that the practical spindle speed may be considerably influenced by the machine rigidity and tool balance, when using, slowly ramp up to the appropriate speed starting from slow speeds • Contact us for a plug screw to block a coolant through hole • If HSK tool holders are used in a machine which does not recommend the center through coolant, the plug screw should be mounted to our tools
