Our take on the Raytech AV-18 Ultimate Rock Polisher 12 in Bowl Vibratory Rock Tumbler

The Raytech AV-18 is a 12-inch vibratory rock tumbler with a 0.18 cu ft bowl that holds 14 to 16 lbs of rock. It is built for harder stones in the 6 to 8 Mohs range and for deburring and polishing metal parts. Vibratory tumbling works faster than rotary drums and keeps stones from banging, but the bowl and motor are heavier and louder than a hobby drum. Its price has held flat: $529.95 at the listed store as of October 30, 2026, the only price recorded in its recent range.

Questions and answers

Is the AV-18 worth it over a rotary tumbler?
If you tumble hard stones in volume or deburr metal, yes. Vibratory action finishes batches in days instead of weeks. For occasional small batches of soft rock, a rotary tumbler costs far less.
What rock can it handle?
Raytech rates it for stones of 6 to 8 Mohs, which covers agate, jasper, quartz and corundum. Softer material like fluorite or opal is better left to gentler methods.
How much rock fits in one batch?
The 12-inch bowl holds 0.18 cu ft, or about 14 to 16 lbs of rock. That is a large batch for a home shop.
Does it come with grit and media?
The tumbler ships as the unit itself; grit, polish and ceramic media are bought separately. Budget for a grit kit with your first order.
How loud is it?
Vibratory tumblers hum and rattle continuously while running. Expect to keep it in a garage or utility room rather than a living space.
When is the price lowest?
The only recorded price is $529.95 at the listed store as of October 30, 2026, with no lower point in its recent range. Watch for lapidary-supply sales rather than expecting frequent discounts.
