! CAUTION

*Nut, adjusting screw, collet and wrench are not included • Weight does not include collet • MEGA ER GRIP is not able to use DIN6499 Form-A collets and ESX collets

To maintain the accuracy of the tool assembly, do not use collets and nuts manufactured by another company with the chuck body of BIG’s MEGA ER GRIP. We cannot guarantee the accuracy statement for our collets if they are assembled on the chuck body of another manufacturer.

• 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
