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. ! CAUTION
*Nut, adjusting screw, collet and wrench are not included • Weight does not include collet • “H” indicates the adjustment length with an adjusting screw • MEGA ER GRIP is not able to use DIN6499 Form-A collets and ESX collets
• The “max” allowable spindle speed listed in the table is directly influenced by the rigidity of the machine and balance of the cutting tool, therefore, the “max” allowable speed may not always be achievable • Adjusting screws cannot be used with models marked
