Vicmarc VM120 Insert 1-1/4" x 8tpi

This insert will adapt the Vicmarc VM120, VM140, and VM150 chucks to any lathe with a 1-1/4" x 8tpi Spindle thread.

Vicmarc's Eccentric chucks and the Vicmarc Oval Device also accept this insert

All left hand, left hand/right hand, Geiger, M30x3.5, M33x3.5 and 1 1/4x8 inserts come with a grub screw locking facility for safety to prevent the chuck from unscrewing itself while turning outboard. Note: When mounting insert onto the chuck, ensure that the grub screw is not protruding past the insert face, and then tighten the insert against the chuck face then tightening the grub screw.
