Heavy Duty Rotary Tumbler Review

This heavy duty rotary tumbler by Tru-Square is one awesome piece of kit!

A rotary rock tumbler, this model has a 15lb capacity, making it ideal for tumbling rocks on a larger scale.

The heavy-duty motor is 115V and is fan cooled to prevent overheating when running for a long period of time.

This rock tumbler is slightly more hardcore than others on the list, for that reason it’s great for people who know their stuff or with big tumbling ambitions!

The motor is exceptionally quiet which is great if it’s running for a long period of time, and the product is easy to use.

This rock tumbler is built to last, made of high quality materials with a sturdy motor and barrel.

While parts of this model will eventually experience wear and tear, it is generally the parts which are cheap to replace – so shouldn’t cause you too much sleep! If you are looking for the best rock tumbler for larger rocks then look no further!

Pros

  • Very quiet
  • Great for tumbling on a large scale
  • Good quality
  • Fan cooled

Cons

  • Pricey

National Geographic Starter Rock Tumbler Kit Review

Next up, we’ve got the National Geographic Starter Rock Tumbler Kit which has all the features of the National Geographic Hobby Kit minus a select few, and costs a fair amount less.

Like the hobby kit, this starter kit is a great introduction to rock tumbling, providing everything you need to get cracking.

The kit includes a rock tumbler, four polishing grits, a sifter, jewellery fastenings, a full-colour 8-page learning guide and nine types of real, rough gemstones including Amethyst, Agate, Dalmatian Jasper, and Aventurine.

The kit is easy to use and perhaps slightly more geared towards beginners than the hobby kit, as it’s cheaper and lacks a couple of the more advanced features.

The included rock tumbler is leak-proof and the motor relatively powerful. While you tend to get what you pay for with these kits, I certainly found the tumbler to be of a good standard, polishing and smoothing all the included gemstones plus a few more.

The one thing this tumbler lacks however (and parents take note!) is a noise-reducing barrel. While the hobby kit includes a rubber barrel, the tumbler included in this starter kit is plastic. This means that when the motor is running, you really know about it!

For this reason, the starter kit is best purchased if you have a separate room for tumbling – ideally a sound-proof room! It also lacks the automatic shut off timer which other National Geographic tumblers have, but this is more of an added luxury, as opposed to a necessity!

Finally, this rock tumbler kit has a 100% satisfaction guarantee and many of National Geographic’s proceeds go towards exploration, conservation, research and education programs – so you’re doing your bit while you shop!

All in all, this is one of the best rock tumbler packages on the market that is perfect for beginners and offered at a fantastic price.

Pros

  • The perfect beginner starter kit, no fuss, easy to use
  • Great price for what is included
  • A trustworthy, reliable and generally great quality brand

Cons

  • Noisy! Plastic barrel
  • Not very durable

Advanced Professional Rock Tumbler Kit Review

The instructions are very clear and easy to follow, which is important for anyone new to rock tumbling. The multi-day timer is a great bonus feature that isn’t usually found on budget tock tumblers. 

It can polish small and large-sized rocks at the same time without damaging fragile rocks. The polishing powder that it comes with is great, and you certainly could do with receiving a little more. 

This rock tumbler does not look or feel like a toy, and it works very professionally. It can polish rough rocks in a very reasonable time, too which is good. 

Pros

  • Easy to use
  • Polishes quickly
  • It has a timer
  • Multiple settings

Cons

  • May overheat
  • The belt tends to move about a lot

Leegol Electric Hobby Rock Tumbler Machine Review

The rubber barrel is very quiet for a rock tumbler device. If you know what to do and you not new to rock tumbling, this is a great rock tumbler to use. 

I particularly like that the motor doesn’t get very hot even though it is on for hours at a time. The tire is also very sturdy and durable and will last you a number of sessions before showing signs of wear and tear. 

If you want to make any modifications to this rock tumbler, then you can. Small modifications will not interfere with the rest of the features.

Pros

  • Durable
  • Little wear and tear
  • Easy to use
  • Very quiet

Cons

  • Hard to disassemble and reassemble

Buying Guide​

If you are on the hunt for the best rock tumbler on the market, by now you have probably realized that it isn’t as easy as it sounds. Now that you have read the reviews for our top tumblers, take a look at this buying guide to make the process easier for you. So, let’s get started!

​What to Look for When Buying a Rock Tumbler

Using rock tumblers to turn rough and jagged rocks into smooth and aesthetic stones will really make your project run smoother. Not all rock tumblers produce smooth and round stones which can be very frustrating, so hopefully the following information will guide you to the best rock tumbler for your needs. 

The tumbling process is simple and shouldn’t take a long time with the right tool. The following three barrel features are the most important when it comes to rock tumblers, whether you are looking for a tumbler for yourself, or as a gift for a friend, getting a high-quality tumbler will put a smile on all of your faces. 

Barrel Size 

A 3-pound barrel capacity is a great barrel size to go for if you are a beginner. Rocks between 0.25 inches and 1.25 inches are appropriate for rock tumblers with a 3-pound capacity. This should be appropriate for the majority of hobbyist jobs, and even for professionals. 

Barrel Material 

There are two materials that are most commonly used for tumbler barrels and they are plastic and rubber. Rubber is most people’s number one choice of barrel material as they tend to last longer and make far less sound during the tumbling process than tumblers with a plastic barrel. 

Barrel Configuration

Typically, you will find two types of barrel configurations for you to choose from. Here is an explanation of the two:

Rotary 

A rotary barrel configuration uses water and abrasive grit to smooth out the stone by turning the barrel. This method works by causing the rocks to collide with one another as well as with the abrasive grit to smooth out the stones. 

Vibratory 

A vibratory barrel system shakes that are inside the barrel to smooth them off. The barrel does not turn, and because of this, the process may take a little longer. 

Other Things to Think About 

Rock tumblers are used when you want to make something creative and fun such as jewelry or display pieces, so there are some more important factors that you should consider before choosing your rock tumbler. If your rock tumbler ticks the following boxes, then your experience will stay fun and lighthearted and you will glide through it with little frustration. 

  • Ease of use 
  • Price point 
  • Frequency of use 
  • Who is using it (beginners, kids, professionals)
  • Rock size compatibility
