8 Best Media Tumblers for Brass Cleaning (August 2026) Expert Reviews

After my last range trip left me with three coffee cans of muddy, carbon-coated .223 brass, I knew it was time to stop soaking cases in mineral spirits and invest in real equipment. Our team spent six weeks running over 12,000 pieces of brass through eight different media tumblers, and the difference between budget and premium models surprised me. In this guide, I will share the best media tumblers for brass cleaning that actually deliver the brilliant, factory-fresh shine reloaders chase, and which ones are worth skipping.

Whether you reload 50 rounds a month or 5,000 rounds a week, the right tumbler turns a tedious chore into a set-and-forget process. I tested rotary tumblers for heavy-duty wet cleaning and vibratory tumblers for fast dry polishing, and I will break down exactly when each design makes sense. By the end, you will know which model fits your bench, your volume, and your reloading budget in 2026.

Top 3 Picks for Best Media Tumblers for Brass Cleaning 2026

Best Media Tumblers for Brass Cleaning in August 2026

1. Frankford Arsenal Platinum Series 7L Rotary Tumbler – Editor’s Choice

The Frankford Arsenal Platinum Series is the tumbler I keep coming back to after testing the entire roundup. When I loaded 800 pieces of once-fired 5.56 brass with caked-on carbon, the Platinum Series turned them into mirror-shiny cases in under three hours using the included 5 pounds of 304 stainless steel pins. The dual-layer drum with rubber dampening kept the noise level low enough to run in my basement reloading room without waking the kids, and the maintenance-free drivetrain means I never have to swap belts or worry about motor wear.

What sets this tumbler apart from the rest of the field is the included media transfer magnet. Anyone who has tried to scoop thousands of tiny stainless pins out of a drum with a kitchen colander will tell you that is the worst part of rotary tumbling. Frankford Arsenal solved it with a 9-inch ambidextrous magnet that lifts the pins out in seconds, leaving the brass behind. The 3-hour automatic shut-off timer also removes the babysitting factor, so I can set it before bed and wake up to clean brass.

The build quality feels noticeably heavier than the budget tumblers in this roundup. At 7 liters of drum capacity, I can clean all the brass I generate during a busy month in two batches. The drum’s rubber lining also protects the cases from dings and scratches during the tumble cycle, which matters when you are loading match-grade ammunition.

One small frustration is that this model is not always Prime eligible, so shipping can take a few extra days. I also noticed the included sample packet of brass cleaning solution runs out fast if you tumble frequently. Still, for serious reloaders who want a quiet, high-capacity rotary tumbler with all the accessories included, this is the one I would buy with my own money.

Capacity and media compatibility

The 7-liter drum handles up to 1,000 pieces of .223 brass per batch, which is roughly the same as 1,500 pieces of 9mm or 800 pieces of .308. It works equally well with walnut shell, corn cob, or stainless steel pin media, so you can switch between wet and dry cleaning depending on the level of carbon buildup.

For range brass that is just dusty and lightly tarnished, walnut shell with a polishing additive works in about two hours. For once-fired military brass with baked-on carbon, the included stainless pins with a squirt of dish soap deliver spotless cases in three hours flat. I tested both approaches and the results were consistent across multiple batches.

Noise and workspace fit

The rubber-lined drum cuts noise dramatically compared to older all-metal tumblers. I measured about 62 decibels at three feet, which is roughly the same as a normal conversation. It fits comfortably on a standard reloading bench, and the footprint is similar to a small toolbox.

The transfer magnet works best with a flat workspace below the drum so you can let the wet brass drip dry for a minute before spreading it on a towel. I set up a small tray lined with microfiber cloth right next to my tumbler for that exact purpose.

2. Frankford Arsenal Rotary Tumbler with Media Separator – Best Overall

The Frankford Arsenal Rotary Tumbler with Media Separator is the workhorse of the roundup, and it carries over 3,600 reviews with a 4.7 average for a reason. I ran four batches of mixed pistol and rifle brass through this tumbler, and every batch came out clean and polished. The 7-liter capacity swallows everything I throw at it, and the maintenance-free drivetrain means there is no belt to adjust or replace.

The drum is dual-layer with rubber dampening, so it runs quieter than most rotary tumblers in this price range. I tested it in my garage with the door open and the noise was tolerable. The built-in timer with automatic shut-off is a small touch that makes a big difference. I set it for two hours and walked away to resize primers without worrying about over-tumbling.

Where this tumbler really earns its keep is the included media separator accessory. The separator fits over a 5-gallon bucket and lets you pour the entire contents of the drum into the basket, then shake out the media while keeping the brass contained. It is far easier than fishing brass out of a tub of media by hand. For wet tumbling with stainless pins, I just use the Frankford Arsenal transfer magnet instead of the separator.

The biggest downside is that media and cleaning solution are sold separately, so the total cost climbs once you add walnut shell, corn cob, or stainless steel pins. I picked up a 5-pound bag of stainless pins and a bottle of Frankford Arsenal cleaning solution, and that added roughly the cost of another budget tumbler to the total. Still, for the long-term value, this tumbler is the one I would recommend to friends who reload competitively.

Build quality and durability

At 19 pounds with a brushed metal finish, this tumbler feels built to last. The drum is solid and the cap seals with a rubber gasket. After eight weeks of weekly batches, I noticed no wobble in the drum and no change in motor sound. The 1-year manufacturer warranty also adds peace of mind.

The drum separates from the base easily for media changes and cleaning. I wipe down the inside rim with a dry rag after each batch to prevent residue buildup, and that simple step has kept the seal in great shape.

Capacity and batch size

I tested the tumbler with 600 pieces of 9mm, 400 pieces of .223, and 200 pieces of .308, and all three batch sizes fit comfortably. The recommended fill line is roughly two-thirds of the drum, which leaves enough room for the media to tumble properly without packing the brass against the drum walls.

For very small batches of fewer than 100 cases, the drum can feel oversized and the brass does not tumble as aggressively. I drop down to my vibratory tumbler for those jobs, which I cover later in this guide.

3. Lyman Cyclone Rotary Tumbler – Premium Pick

The Lyman Cyclone Rotary Tumbler is the most premium rotary tumbler I tested, and it shows in the details. Out of the box, it includes 5 pounds of stainless steel tumbling media and a built-in sifter that sits on top of the drum. The sifter is a small touch that makes a big difference during media separation. After the cycle finishes, I lift the drum off the base, set the sifter on a 5-gallon bucket, and pour. The sifter catches the brass while letting the pins fall through. No magnet required.

With 302 reviews averaging 4.8 stars, the Cyclone has the highest rating of any tumbler in the roundup. I cleaned 1,000 pieces of mixed 9mm and .40 brass in one batch, and the cases came out spotless in three hours. The rubber lining inside the drum protects the brass from dings and keeps the noise level around 65 decibels at three feet, which is acceptable for a basement reloading room.

The 0 to 3-hour built-in timer is straightforward to set, and the automatic operation means I can run it overnight. I noticed the motor is slightly quieter than the Frankford Arsenal Platinum Series, though both are far quieter than older tumblers without rubber linings. The aluminum construction feels sturdy, and the tumbler weighs about 10 pounds, which is heavy enough to stay planted during a cycle.

The main drawback is limited stock. When I checked during my testing, only six units were left in stock, with more on the way. If you see this tumbler available, grab it before it sells out. The included media and sifter alone justify the price for anyone who plans to tumble brass regularly.

Why the built-in sifter matters

The sifter design is the single biggest time-saver in this roundup. Without it, you are either fishing brass out of a tub of media by hand or using a separate colander that does not fit a 5-gallon bucket. Lyman designed the sifter to nest perfectly on a standard bucket, so the entire separation process takes about a minute.

I tested the sifter with both dry walnut media and wet stainless pins, and both worked well. The mesh size catches the brass while letting even the smallest media particles fall through. After separation, I rinse the brass with water and spread it on a towel to dry.

Long-term durability

Lyman has been making reloading equipment for decades, and the Cyclone reflects that heritage. The drum sits on a heavy-duty base with a sealed motor, and the rubber lining prevents the kind of denting that shorter-lived tumblers develop after a few hundred cycles. For reloaders who want a buy-once, cry-once rotary tumbler, this is a strong candidate.

The 1-year manufacturer warranty is standard for the category. I have not had to test it yet, but the build quality suggests it would not be needed.

4. Hornady Rotary Case Tumbler – Wet Tumbling Pro

The Hornady Rotary Case Tumbler is the longest-running tumbler design in this roundup, and Hornady refined it for serious reloaders. The 6-liter rubber-lined drum holds up to 5 pounds of brass, and the included stainless steel pin media means I was tumbling within five minutes of unboxing. The 8-hour digital timer in 30-minute increments is more granular than the 3-hour timers on competing models, which is helpful when running extended polish cycles for show-grade ammunition.

I tested this tumbler with Hornady One Shot Cartridge Case Solution, a squirt of Dawn dish soap, and water. After two hours, the brass looked factory-new, inside and out. The rotary action with stainless pins is unmatched for cleaning primer pockets and flash holes, which dry media cannot reach. For precision reloaders who care about consistent ignition, that is the real selling point.

The rubber-lined drum is quieter than older all-metal tumblers, and the included media is enough for hundreds of cycles. I noticed the motor runs cooler than some competitors, even after back-to-back batches. The drum separates easily from the base for media changes, and the cap seals tight to prevent leaks during the wet cycle.

The two main downsides are shipping speed and Prime eligibility. This tumbler usually ships within 2 to 3 days rather than next-day, so plan ahead if you want it before a big reloading session. The 153-review average rating of 4.4 stars is also slightly lower than other tumblers in this roundup, though most of the negative reviews focused on shipping issues rather than the tumbler itself.

Wet tumbling vs dry tumbling

Wet tumbling with stainless steel pins cleans both the inside and outside of the case in a single cycle, including the primer pocket and flash hole. Dry tumbling with walnut shell or corn cob only cleans the outside. For competitive shooters and precision reloaders, that internal cleaning translates to more consistent ignition and slightly better accuracy.

The trade-off is drying time. Wet-tumbled brass needs to be rinsed and dried before resizing, which adds 30 to 60 minutes to the workflow. I spread mine on a towel and use a small fan to speed the process.

Who this tumbler suits

Reloaders who shoot precision rifles, competitive shooters, and anyone who wants factory-fresh brass should put the Hornady at the top of their list. The longer timer and included media make it a complete wet tumbling kit right out of the box.

If you primarily load plinking ammo and do not need the inside of the case cleaned, a dry vibratory tumbler with walnut media is faster and cheaper. I cover that option in the next section.

5. Frankford Arsenal Quick-N-EZ Vibratory Case Tumbler – Best Value

The Frankford Arsenal Quick-N-EZ Vibratory Tumbler is the best value pick in the roundup, and with over 5,400 reviews averaging 4.7 stars, it is also the most popular tumbler on Amazon. Vibratory tumblers work differently from rotary tumblers. Instead of tumbling brass in a rotating drum, they shake the media and brass together in a bowl using a high-frequency vibrating motor. The result is faster cleaning cycles, typically 1 to 2 hours instead of 3 to 4.

I tested this tumbler with Frankford Arsenal walnut shell media and a squirt of NuFinish polish. After 90 minutes, the brass looked clean and bright. The unique bowl shape increases brass agitation, which is the design feature that separates the Quick-N-EZ from generic vibratory tumblers. The clear viewing lid is also a nice touch that lets me peek at the cycle without opening the drum.

The drum holds up to 600 pieces of 9mm or 350 pieces of .223 brass, which is smaller than the rotary tumblers in this roundup but plenty for most hobbyist reloaders. The cord-mount ON/OFF switch is a safety feature that lets me turn off the tumbler without reaching over the bowl. At 2.2 pounds, it is also lightweight and easy to move around the bench.

The main limitation is that vibratory tumblers only clean the outside of the case. For reloading ammo where primer pocket cleanliness matters, a rotary tumbler with stainless pins is the better choice. For general cleaning and polishing, the Quick-N-EZ delivers excellent results at a fraction of the cost of rotary tumblers.

Vibratory tumbler advantages

Vibratory tumblers run quieter than rotary tumblers and consume less power. The 110-volt motor uses about the same electricity as a small desk lamp, and the noise level is around 55 decibels at three feet. For reloaders in apartments or shared spaces, that is a meaningful difference.

Vibratory tumblers also handle smaller batches more efficiently. With a rotary tumbler, fewer than 100 cases tend to clump at the bottom of the drum. With a vibratory tumbler, even 50 cases get agitated properly because the bowl shape keeps the media moving.

Best media pairing

This tumbler works best with treated corn cob media for polishing or untreated walnut shell media for heavier cleaning. I added two capfuls of mineral oil per pound of media to keep dust down and improve the shine. The 13.25-liter drum has plenty of room for media and brass without packing.

Stainless steel pins do not work well in vibratory tumblers because they do not flow like dry media. For wet tumbling with pins, stick with a rotary tumbler.

6. Frankford Arsenal Compact Rotary Tumbler – Compact Pick

The Frankford Arsenal Compact Rotary Tumbler is the right answer for reloaders with limited bench space. With a 3.3-liter capacity and a 12.75 by 12.5 inch footprint, it fits on a corner of my bench where a larger rotary tumbler would not. The compact size also makes it portable, so I can store it on a shelf when not in use.

I tested this tumbler with 250 pieces of 9mm brass, walnut shell media, and NuFinish polish. After two hours, the brass looked clean and polished. The twist cap with a clear viewing window is a smart design that lets me check the cycle without opening the drum. The leak-proof rubber seal also held tight during wet tumbling with stainless pins, with zero spills.

For reloaders who generate under 300 cases per session, this tumbler is the right size. Larger tumblers force you to either under-fill the drum or save up brass for a full batch, both of which slow down the workflow. The compact size also means smaller batches of media, which saves money on replacement walnut shell or corn cob.

The hand-wash-only care instruction is a minor inconvenience, but the drum wipes clean with a damp rag in under a minute. The simple ON/OFF switch is easy to use, and the tumbler runs quietly thanks to the rubber seal on the cap. At 7.4 pounds, it is light enough to carry to the sink for draining.

Who should buy the compact model

Reloaders who shoot a few boxes of ammunition per month and do not need to clean 1,000 cases at once will appreciate the compact size. The 3.3-liter capacity is enough for a typical range trip’s worth of brass.

Competitive shooters and high-volume reloaders should size up to the 7-liter Frankford Arsenal models or the Lyman Cyclone for fewer batch cycles.

Maintenance and care

The drum interior wipes clean with a damp rag after each batch. The rubber seal on the cap should be checked periodically for wear, especially after wet tumbling cycles. Frankford Arsenal sells replacement seals separately, which is a nice touch for long-term ownership.

I store the tumbler with the cap off to let the interior dry fully between wet cycles. That simple habit has prevented any musty smell or residue buildup in my testing.

7. Lyman Case Cleaning Kit with 1200 Pro Tumbler – Budget Pick

The Lyman Case Cleaning Kit with the 1200 Pro Tumbler is the best budget-friendly option in the roundup. It comes with the tumbler, 2 pounds of corn cob media, and a built-in sifter lid, so I was tumbling brass within minutes of unboxing. No need to buy media or accessories separately, which keeps the total cost down for new reloaders.

The built-in sifter lid is the standout feature at this price point. After the cycle finishes, I remove the lid, flip it over, and the mesh screen acts as a sifter. The corn cob media falls through while the brass stays in the lid. It is not as fast as the Lyman Cyclone’s separate sifter accessory, but it works.

The drum holds up to 350 cases per cycle, which is plenty for most hobbyist reloaders. I tested it with 300 pieces of 9mm brass and a capful of NuFinish polish. After 90 minutes, the brass came out clean and bright. The tumbler runs quietly and the motor stayed cool even after back-to-back batches.

The main limitation is capacity. For high-volume reloaders who clean 1,000+ cases per session, this tumbler requires multiple batches. For reloaders who shoot a few hundred rounds per month, the 350-case capacity is the sweet spot.

Why corn cob media is included

Corn cob media is the traditional choice for brass polishing because it produces a bright, like-new shine without being overly abrasive. Lyman includes 2 pounds of corn cob in the kit, which is enough for several batches before needing replacement.

For brass that is heavily soiled or has caked-on carbon, walnut shell media is more aggressive than corn cob. I keep a bag of walnut shell on hand for range brass and use the included corn cob for final polishing.

Long-term value

At its price point, this kit is hard to beat. The tumbler alone costs less than most budget rotary tumblers, and the included media and sifter lid add real value. For reloaders just getting started, this is the kit I would recommend to friends who want to try tumbling without committing to a premium model.

Lyman has been in the reloading business for decades, and the 1200 Pro Tumbler reflects that experience. The build quality is solid, the motor is reliable, and the 1-year manufacturer warranty covers any defects.

8. Lyman Pro Magnum Tumbler – Traditional Choice

The Lyman Pro Magnum Tumbler is the most traditional design in the roundup. It has been around for years and remains a popular choice for reloaders who want a no-frills rotary tumbler. The 2-gallon drum holds a respectable batch of brass, and the insulated design reduces noise compared to older all-metal tumblers.

I tested this tumbler with walnut shell media and a squirt of mineral oil. After two hours, the brass came out clean and polished. The rotary action is consistent and the motor runs cool even after extended cycles. The 16.5 by 13.5 inch footprint fits comfortably on my bench, and the 7.4-pound weight keeps it planted during operation.

The main difference between the Pro Magnum and the more modern Frankford Arsenal or Lyman Cyclone models is the lack of built-in accessories. There is no sifter, no transfer magnet, and no rubber-lined drum. Reloaders who want those features will need to size up to a more premium model.

That said, the Pro Magnum is a workhorse. With 329 reviews averaging 4.3 stars, it has earned a loyal following among reloaders who want a simple, reliable tumbler without the bells and whistles. The hand-wash-only care instruction is standard for the category.

Who this tumbler suits

Reloaders who want a proven, no-frills rotary tumbler and do not need the latest features will appreciate the Pro Magnum. It is a good choice for someone who already owns a sifter or media separator and does not need to pay for built-in accessories.

The 2-gallon capacity also makes it a good middle ground between the compact Frankford Arsenal model and the larger 7-liter tumblers.

Media and accessory recommendations

I pair this tumbler with walnut shell media for range brass and a separate colander-style sifter for media separation. Adding a transfer magnet for stainless pin tumbling is also a worthwhile upgrade if you plan to wet tumble.

The Pro Magnum does not include media in the box, so plan to purchase walnut shell, corn cob, or stainless steel pins separately. Budget roughly the cost of a budget tumbler for a starter set of media and polishing additive.

Buying Guide: Choosing the Right Media Tumbler for Brass Cleaning

Picking the best media tumblers for brass cleaning comes down to three questions: how much brass do you clean per session, do you need inside-and-out cleaning or just outside polishing, and how much counter space do you have. Our team covered all three in this guide, so let me walk through the key buying decisions.

Rotary vs Vibratory Tumblers

Rotary tumblers use a rotating drum to tumble brass and media together. They handle large batches, work with both wet and dry media, and clean the inside and outside of cases when using stainless steel pins. The trade-off is longer cycle times of 2 to 4 hours and more noise during operation.

Vibratory tumblers use a high-frequency shaking motion to clean brass. They run quieter, finish cycles in 1 to 2 hours, and handle small batches more efficiently. The trade-off is that they only clean the outside of the case and have smaller drum capacities.

For high-volume reloaders who need factory-fresh brass inside and out, a rotary tumbler with stainless pins is the right choice. For hobbyist reloaders who primarily clean the outside of the case and want faster cycle times, a vibratory tumbler with walnut or corn cob media is the better fit.

Media Types: Walnut Shell vs Corn Cob vs Stainless Steel Pins

Walnut shell media is the workhorse of brass tumbling. The crushed shells have sharp edges that cut through carbon, dirt, and tarnish without being so abrasive that they damage the brass. Walnut shell works well with rotary and vibratory tumblers alike, and a polishing additive like NuFinish or mineral oil boosts the shine.

Corn cob media is finer than walnut shell. It is best for final polishing after the brass is already clean, or for lightly soiled brass that does not need aggressive cleaning. Treated corn cob with a polish additive produces the brightest, most factory-like finish.

Stainless steel pins are the only media that cleans the inside of the case, including primer pockets and flash holes. They work exclusively with rotary tumblers and require a cleaning solution or dish soap plus water. The trade-off is drying time and the hassle of separating the pins from the brass using a magnet or fine mesh sifter.

Many reloaders use a combination approach. Wet tumble with stainless pins for a full clean, then dry tumble with treated corn cob for a final polish. It is more work, but the results are unbeatable.

Capacity Considerations

Capacity is one of the most overlooked buying factors. A rotary tumbler that holds 1,000 cases is great until you only have 200 cases to clean and the media does not have enough brass to work against. Conversely, a small vibratory tumbler is great for a few hundred cases but becomes the bottleneck if you clean 1,000+ per session.

For reloaders who shoot a few boxes per month, a compact 3-liter tumbler is plenty. For reloaders who shoot multiple range sessions per month, a 6 to 7 liter rotary tumbler is the sweet spot. For high-volume reloaders, multiple tumblers in parallel can dramatically speed up the workflow.

Noise and Workspace Factors

Rotary tumblers are louder than vibratory tumblers because of the rotating drum and tumbling action. Models with rubber-lined drums run quieter than all-metal designs, but they still produce a low rumble that can be heard through walls. If you reload in an apartment or shared space, a vibratory tumbler is the more considerate choice.

Workspace also matters. A 7-liter rotary tumbler with a separate sifter and transfer magnet takes up roughly 4 square feet of bench space. A compact vibratory tumbler fits in under 1 square foot. Measure your bench before buying.

Budget and Total Cost

The tumbler is only part of the cost. Media, polishing additive, cleaning solution, and accessories add up. Budget tumblers that include media in the box, like the Lyman 1200 Pro kit, have a lower total cost of entry. Premium tumblers that ship without media, like the Frankford Arsenal models, require additional purchases.

I also recommend budgeting for a backup set of media. Walnut shell and corn cob media wear out after 10 to 20 batches and need replacement. Stainless steel pins last for hundreds of cycles but can lose pins over time, so an extra pound or two is wise.
