Case Cleaning Tumblers — Rotary & Vibratory

Vibratory tumblers typically clean a batch of brass in 2-4 hours using dry media, while rotary tumblers—especially wet stainless steel pin systems—can take 2-6 hours depending on load size, media type, and desired shine level. Larger capacity drums may require longer cycles for uniform results.

Common dry media options include corn cob and walnut shell, ideal for vibratory tumblers. Rotary tumblers often use stainless steel pins with water and a cleaning additive for a wet tumbling process that reaches inside case necks and primer pockets for a deep, mirror-like clean.

Yes, most rotary and vibratory tumblers are sized to accommodate mixed batches of pistol and rifle casings. Drum capacity determines how many cases can be cleaned per cycle, so reloaders processing large rifle brass should confirm bowl or drum volume before purchasing.

Capacity varies by model, with smaller vibratory units handling a few hundred cases and larger rotary drums processing over a thousand casings per cycle. Selecting the right capacity depends on your reloading volume and whether you're cleaning for personal use or commercial production.

Yes, wet tumbling with stainless steel media requires a separate drying step, typically using a dedicated brass dryer or air-drying trays, since the cases and media absorb water and cleaning solution during the cycle. Dry vibratory tumbling does not require this additional drying stage.

Routine maintenance includes replacing worn media, cleaning out drum or bowl residue, inspecting motor bearings and belts for wear, and lubricating moving parts as specified by the manufacturer. Proper maintenance extends tumbler lifespan and ensures consistent cleaning performance across cycles.
