Fashion Lee Valley JessEm Insert Rings

To vary the size of the bit aperture, these glass-filled polycarbonate flush insert rings securely lock into the 3 7/8″ opening with an easy 1/8 turn.

We offer two sets, each with four inserts: one set has center holes of 1/4″, 1/2″, and 2 1/2″, plus a 1 3/16″ through bore/1 3/8″ counterbore insert for use with guide bushings; the second set contains blanks for making zero-clearance inserts. Each set fits any JessEm lift.
