This works with Ra2 Rotary tool along with most other Rotary chucks. For continuous change of tumblers without having to fool with the chuck every tumbler change. My device is a snug fit as it needs to be for tumblers to spin around evenly and without falling off. The gasket isn't included. You just use the ones from your favorite tumblers for a better fit. Fits with the small and large chuck claws. Small on the inside and large on the outside.
