Best Rock Tumblers to Buy in 2019 – Complete Guide

Jun 20, 2019

Introduction to Rock Tumbler and Lapidary Kits

The rock tumbler comes in many different types and brands, they are available in a variety of sizes (and to some extent shapes) and they are manufactured to meet the needs and expectations of the users whom they are aimed at on an individual basis. For example, if you need your rock tumbler for professional lapidary (perhaps for jewelry making and selling), then you will probably not be satisfied with either the capacity or final polish depth of finish and shine provided by the lower end of the market or the kind of tumbler which has been made for children as an introduction to the hobby. Naturally, this is a more extreme example and in essence compares the two ends of the scale of rock tumblers available – however there are variables all along the range which can be considered based on application and requirements that can influence the decision regarding which rock tumbler might be best suited to your requirements.

  • Kids

Best Rock Tumblers for Kids

The design of a kids rotary rock tumbler and starter kit is very often different than the design of a professional / hobbyist tumbler. Very often the parts tend to be made of plastic, and for safety reasons the motors are well hidden with all the pointed parts rounded off smoothly. The moving parts such as the rotating barrel are also sometimes covered with a protective screen. There is also sometimes a timer facility built into these which allows the owner to set the machine going for a length of time, automatically stopping the rotation of the barrels after this period (measured in days normally).

It should realistically be noted that children must be supervised by an adult at all times when participating in tumbling rocks, because after all, we are using electrical products, chemicals, sharp stone, sometimes a rock hammer and more often than not, implements found in the typical household kitchen!

You may want to have a read of the basic instructions for using a rock tumbler which we have provided here, and within these you will encounter some of the limitations of choosing a very basic kit for kids. Having said this, you should be able to get a few good batches of rocks before running into problems and the related costs can be kept to a relative minimum – if the hobby grows, more expensive equipment can be bought if needed.

Rock Tumbling Guide

There is definitely an art to getting a fantastic shine on the rocks you decide to put through a rock tumbler, and whichever device you choose or own already, the best results will always come with a combination of time and patience. This doesn’t apply to “waiting for it to finish” – that is a must, what we mean by time and patience is really more specific to how your skill will develop as you tumble more and more batches of rough rock to a standard you are satisfied with, and indeed, your standards will probably raise the more rocks you tumble.

So whilst it isn’t really possible to attain the art by reading guides alone, learning the basics from the very beginning will certainly get you on the road to success if the directions below are followed very carefully. Many people are turning their hand to lapidary and remember owning a rock tumbler when they were younger – if you fall into this category, we are certain that the sound of the barrel turning will bring back some long lost memories. Happy Tumbling!

Preparing to use a Rock Tumbler

Perhaps often overlooked are important factors when using a rock tumbler. Read this preparation page to ensure you are ready to leave an electronic device, powered up, alone and running for long periods of time in a safe environment.

Step 1 – Rough Rock to Shaped Rock – 80 Grit

The idea behind the first step is to take your rough rock and grind it (tumble it) down into a form which is indistinguishable (in shape) from the final product. The size and shape of the rocks at the end of this first step will be more or less the same as they will be once they are completely shiny at the end of the fourth step.

Step 2 – A Two part Process of 220 then 400 Grit

Step 2 of using a rock tumbler is in itself a two part process. These tumbles will not actually shape the rock, instead it will work on the outer surface making the rocks smoother and smoother until they are ready for the final polishing which is the ultimate goal.

Step 3 – The Final Polishing of your Tumbled Rock

And now for step 3. This will add a shine to the gemstones you have worked so hard in the tumbler now for many weeks – it is the last stage. Doing this part right will make it all worthwhile, so apply concentration to how clean and free from grit the barrel and rocks are and the results will be amazing.

Types of Rock Tumblers

There are many manufacturers available on the market who are producing Rock Tumblers for Kids. Yes, Kids too can make use of the Rock Tumbler to work with a variety of rocks and stones.

Rotary Tumbler

Rotary Tumbler is also known as Rotating Tumbler which is highly used by the professionals. Rotary Tumblers are high in demands as they offer professional-grade results with the types of Stone and Rock that you select.

In this type of Tumbler, rocks fall over and over again on each other within the barrel. This way the Rotary Tumbler polishes the stones and rocks. This is the same method which is used by the Ocean.

If you ask us, we recommend you to go with the brand which has been in the market for years. Always choose a trusted brand when buying a new Rotary Tumbler. When you go with a branded Rotary Tumbler unit, you will not have to worry about the performance and quality of the machine.

Rock Tumbling requires a number of days and for that reason, you will have to replace some parts of the machine especially if you use it on a regular basis. For that reason, you need to choose a brand who also manufacturer the different parts of the Rock Tumblers.

Things to Consider while buying a Rock Tumbler

Rock Tumbler requires professionalism and for that reason, there are many things you need to consider first before buying a new Rock Tumbler machine. Here we have listed down some things which should be considered first. The following list will help you to pick the best and suitable rock tumbler machine for your needs.


There are numerous manufacturers available on the market with a range of different types of Rock Tumbler machines. If you are looking for a rock tumbler machine for your kids, then you should pick a branded rock tumbler which comes with a good warranty.

If we talk about popular brands, then Thumbler and Lortone are the most popular brands with a range of Rock Tumblers for both, Kids and professional users. It is highly recommended for you to go with the branded Rock Tumbler machine instead of going with a non-branded and cheap one.

Barrel Size

The size of the barrel is the first thing you need to consider as it decides the capacity of the machine. The size of the barrel on a Rock Tumbler machine is measured in Weight. The most common size of the barrel on the Rock Tumbler is of 3 lbs. If you are a beginner, then 3 lbs of barrel size are suitable for you.

If we talk more about the size, with a 3 lbs of barrel size, you can use rocks and stones up to 2 lbs. The other pound should be filled with water or grit as per the type of rock you use on the machine.

If you are into professional rock tumbling, then are many options of Rock Tumblers available on the market with 6 lbs to 12 lbs of size. For commercial use, the Rock Tumbler machine comes with a larger size of 20 lbs to 40 lbs. They are made of heavy-duty materials and designed to last for years.

Depending on your basic needs and the size of the rocks you will work with the machine, you need to choose the right size of the Rock Tumbler. If you go with heavy duty for smaller tasks, then you won’t get the desired results with it. Always go with a suitable size as per your needs.

Barrel Material

Different manufacturers are using different materials to manufacturer their Rock Tumbler machines. The main part on the Rock Tumbler machine is the Barrel. Some manufacturer offers multiple barrels on their new generation machines.

In today’s world, barrels are made of either rubber or plastic materials. Rubber barrels are highly used in the new generation rock tumbler machines as they reduce noise while tumbling and they are not good for the people who don’t like noisy environment.

Professional-grade tumblers use high-quality rubbers. Rock Tumbling process takes days of time and for that reason, you need to choose the machine which doesn’t make any noise while rock tumbling. The machine you use should be noise free and the material of the barrel should be of rubber.

Single or Multiple Barrels?

Apart from this, you can also use the rock tumbling process with different batches on a single machine. A single batch of rocks requires several weeks to get the desired shape and polish. When you use multiple batches, the process becomes easier and faster. You don’t need to spend weeks of time on a single batch.


Price is also a factor to consider especially if you are a beginner and with low budget. There are numerous types of Rock Tumbler Machines available on the market and you need not go with a cheap machine. Pick the machine with an affordable price tag without compromising with its quality.
