COLLETS

ERC COLLET SET Each ERC collet is inspected twice (0º and 180º) at 4 times diameter to guarantee the runout accuracy. The “AA grade” is marked on only those collets that pass the inspection process for accuracy. The ERC COLLET SET contains all the common collets to cover entire 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 statement for our collets if they are assembled on the chuck body of another manufacturer. ! CAUTION • 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 • Provided with a polypropylene case
