Expanding ring mandrel

Helps make turning rings simple and easy.

VERY LIMITED QUANTITY

Just slip the ring core onto the step that fits best, make sure it's properly seated, then lightly tighten with the allen key. The smallest size ring may require a small squeeze on the mandrel to allow the ring to pop on.

This will cause the mandrel to expand slightly to produce a solid grip on the ring core.

Made from mild steel

Includes a 1/2" diameter shank for use in a collet, 4 jaw chuck or drill chuck

Mandrel Fits USA ring sizes 9-13, whole and half sizes
