• 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 • “H” indicates the adjustment length with an adjusting screw • MEGA.625DS requires the hex socket head screw (M8) for axial adjustment, however, please contact us if using for center through applications • DS types have jet-through coolant supply, thus tools with holes cannot be used
