GRS 004-707 Ring Holder Parts Kit-Contains Collets & Related Parts Only

The GRS 004-707 Ring Holder Parts Kit supplies the collets and all related internal components for the GRS Inside Diameter (ID) Ring Holder — everything except the holder body itself. This kit is the ideal solution for replacing worn parts or fully equipping an existing holder body (available separately as order 104.754).

The GRS ID Ring Holder system is designed to hold a ring from the inside, providing unrestricted access to the ring's entire circumference. The design supports two distinct working modes: adjustable tension using the standard cone for smooth ring rotation during engraving, or firm locking action using the locking cone to keep the ring absolutely rigid for pavé and standard stone setting.

This parts kit includes 20 expanding mandrels (2 sets of 10), covering a range of 10 sizes from 13.5mm through 22.5mm. Two mandrels of each size are included. The kit also supplies 2 standard cones, 2 locking cones, a drawbar, drawbar knob, a hex nut for extended clearance, and a GRS hex wrench. The holder body mounts in a vise or engraving block and is not for use in a BenchMate.
