Mounting the collet in the cap
of a toolholder

Properly mounted collet Unmounting of the collet

For proper mounting of ER collet follow these steps:

  • Put the collet into the cap at slight angle
  • Hook the groove of the collet on eccentric or cylindrical edge of the collet (fig. A)
  • Jam the collet into the cap (fig. B)
  • Screw the cap with collet on the toolholder, so that mounting of the machined tool is possible
