Replacement Inserts For Betterley Tru-Cut Insert System, 4-Pcs.

Description

Our replacement ball bearings are designed to spin at high RPM and are double shielded to give you unparalleled performance. Our Beading Conversion Kit allows you to replace the 3/16″ x 1/2″ O.D. bearing on your profile router bit with a smaller (3/8″) O.D. bearing. The smaller bearing now exposes more cutting surface to give you a ‘bead’ profile. Commonly used with Roundover, Ogee and other profile router bits. Kit comes with bearing, Allen key and bearing screw.
