Lortone Rock Tumblers & Lapidary Equipment

Lortone Rock Tumblers and Lapidary Equipment

Lortone is a long-running American maker of rotary and vibratory rock tumblers and lapidary gear, used by hobbyists and jewelers for more than 40 years to polish gemstones, shape rough rock, and finish metal. This collection carries Lortone tumblers, barrels, drive belts, and replacement parts so you can run and maintain a machine for the long haul. If you have seen forum talk about the brand, here is the short version: Lortone recently changed hands as its longtime owners retired, and the line continues under new ownership. We keep popular Lortone models and spare parts in stock and ship them fast, so you can buy with confidence.

Lortone Rock Tumblers: Rotary and Vibratory Models for Every Project

Lortone's line includes rotary tumblers for multi-stage polishing and vibratory tumblers for fast final polishing. Rotary models handle the full four-stage process, coarse grind, medium grind, fine grind, and polish, with barrel capacities from small hobby sizes like the 3A and 33B up to larger batch units such as the 45C and QT series. Vibratory tumblers shine at the final polish stage, cutting cycle time and delivering a high-gloss finish on pre-shaped stones. Both types use sealed bearings, balanced drums, and motors built for continuous duty, which matters when you run week-long polish cycles.

Choosing Between Rotary and Vibratory Tumblers for Your Lapidary Work

Rotary tumblers are the go-to for raw rock. They tumble stones against each other with grit, gradually rounding edges and smoothing surfaces. We reach for a rotary when we start with rough field-collected specimens that need real shaping. A full polish cycle takes three to four weeks, but the payoff is turning a field find into a display-quality piece.

Vibratory tumblers work faster on pre-shaped material. If you have already rounded stones in a rotary tumbler, or you are working with purchased pre-forms, a vibratory tumbler can deliver a final polish in days rather than weeks. The vibrating action keeps stones in constant contact with fine polish for a glass-like finish without the long cycle. Many hobbyists run both, rotary for rough work and vibratory for the final stage.

Heavy-Duty Construction and Quiet Operation

Lortone builds its tumblers with reinforced frames and rubber barrel rollers that dampen vibration and cut noise. We have run Lortone units in basement workshops and garages, and the quiet operation means you can tumble overnight without disturbing the household. The sealed bearings handle constant load without overheating, and wear parts like belts, barrels, and rollers are widely available, which is part of why these machines last. For detectorists who tumble coins, relics, and found stones, that reliability means you are not fighting a motor or bearing failure in the middle of a cycle.

Integrating Lapidary With Your Field Hobbies

Lortone also offers lapidary grinding and polishing wheels for shaping cabochons and faceting rough. These integrate with the tumbling workflow: rough-shape a stone on a grinding wheel, then finish it in a vibratory tumbler for control over both form and surface quality. It is a natural extension for anyone who collects material in the field. Once you have specimens to process, gear up for the next hunt with our digging tools, dig deeper into prospecting with our gold detectors and broader metal detectors, and if you hunt the coast, our beach detectors turn up coins and small finds worth cleaning and polishing.
