  • Our take on the QT66

    The Thumler's Tumbler QT66 is a rotary rock tumbler built on a larger frame with two 6 lb barrels, so you can run two batches at once. It is the bigger sibling of the single-barrel QT6 and the smaller A-R series, aimed at hobbyists who tumble a lot of rough or want separate grit stages going at the same time. Rotary tumblers like this are slower than vibratory models but give stones a rounder, more polished shape, and the twin-barrel layout is the main reason to pick it over a one-barrel unit.

    Pros
    • Two 6 lb barrels process two batches simultaneously
    • Larger frame than the QT6 for heavier loads
    • Rotary action rounds stones for a smooth, polished finish
    • Simple belt-driven design with few parts to fail
    • Barrels and lids are replaceable, so the unit lasts
    Cons
    • Rotary tumbling takes weeks per batch, slower than vibratory tumblers
    • Heavier and bulkier than single-barrel models
    • Loud while running, so it needs a garage or utility room
    • Barrel lids must be seated well or grit slurry leaks
    • No built-in timer or speed control

    What reviewers say

    Owners of Thumler's rotary tumblers generally rate the build and the twin-barrel capacity highly, and the QT66 is bought mainly for running two loads at once. Complaints center on noise, slow batch times and lid sealing.

    What people mention
    • CapacityPraisedOwners value running two 6 lb batches at the same time instead of waiting on one barrel.
    • NoiseCriticisedReviewers say it is loud enough that it belongs in a garage or basement, not a living space.
    • Lid sealingCriticisedSome owners report slurry leaks when the barrel lids are not seated evenly.
    • BuildPraisedThe frame and motor are described as solid and long-lasting with basic care.
    • SpeedMixedRotary tumbling gives a good rounded polish but takes weeks per batch, slower than vibratory machines.

    Questions and answers

    How is the QT66 different from the QT6?
    The QT66 uses a larger frame and carries two 6 lb barrels; the QT6 has a single barrel. The twin setup lets you run two batches or two grit stages at once.
    How much rock fits in each barrel?
    Each barrel holds up to 6 lb of rock, grit and water combined, so a full load is roughly 3 lb of stone per barrel with the rest as media and slurry.
    Do I need special grit?
    It uses standard silicon carbide grit in coarse, medium, fine and polish grades, plus ceramic or plastic media for cushioning. Grit is sold separately.
    Is it better than a vibratory tumbler?
    Rotary tumblers round stones and give a deep polish but take weeks per batch. Vibratory tumblers are faster and keep shapes sharper but cost more and suit smaller stones.
    Can it run two different grit stages at once?
    Yes. Each barrel is independent, so one can run coarse grit while the other runs a finer stage, as long as you keep the loads and grits separate.
    What comes in the box?
    The tumbler unit with its two barrels and lids. Grit, media and rock are not included.
    Where is the QT66 cheapest?
    At Lortone, for $375.00, as of our latest check.
    What do buyers say about the QT66?
    Rated 5 out of 5 from 6 ratings.
