• BIG’s ERC collets have a maximum clamping capacity of .020/ø (.5mm/ø) • To obtain the best runout accuracy and rigidity, ERC collets for smaller tools have a reduced clamping range • For best results, users should avoid clamping tools with shank diameters less than the recommended clamping range

Conventional DIN collets have a clamping range of 1mm/ø. Never use ERC collets for more than .020/ø (.5mm/ø) below nominal size. 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 stated for our collets if they are assembled on the chuck body of another manufacturer. ! CAUTION
