Your cart is empty.Many professional rock enthusiasts keep a dedicated barrel on hand to complete the final stage of polishing because it can be very difficult to make sure that no grit is left behind in your barrel when switching between shaping and polishing steps in the tumbling process. By having an extra barrel, you don't have to worry about rougher grit scuffing up your gemstones while you are trying to get that finished polish.

I have the grey National Geographic tumbler kit. Came with the small barrel that holds roughly a cup. This one is of the same build and quality. Seems about 3x the size. I don’t think you could go any bigger and still fit on the machine.

Great replacement for the tumbler that came with my NG kit. It seems to be better suited for the unit - it APPEARS to move faster - I MAY be wrong, but it somehow gets the job done more quickly on cleaning beads (about 20 mins). Love it

Once I have finished steps 1 and 2 with the heavier grits, the rock load is reduced quite a bit so this smaller size is perfect for the polishing stages. It works perfectly on the National Geo tumbler I have and the lid seals great. So far it's held up really well but if it tanks, I'll come back and say so in an update. So far so good.

I got this as a spare for my National Geographic tumbler. It's much smaller than the original, but it still works (although it spins at a faster rate due to the smaller size). It's really sturdy and I'm very pleased with it. It's handy for smaller batches.

I got this for my polish stage. I am having a hard time getting my stones to get shiny. This barrel is similar to the original and has a similar design for lids. It is a tad smaller which is good for me cause I use a lot of filler in both.

Needed a replacement tumbler for my son's older National Geographic Rock Tumbler Set. I had read in other reviews that this would work, and it DID! So I ordered another to have another barrel on-hand. Very glad I did. Great price, Arrived very quickly. Very pleased with this purchase. Thanks to the other Reviewers who confirmed this tumbler would fit the Nat Geo sets, it fit our perfectly.Happily Recommend!

I needed a replacement barrel for my rock tumbler set up.. I was hoping for a bigger barrel but when I saw the outrageous prices that folks were charging I was discussed at the greed of some people. your price was how ever reasonable so I ordered it. I am glad to say I have for a 2 pound tumbler it is excellent I am thinking once I get the rest of my things set up again I will get another one. I have a young lad down the street that wants to get into this hobby.. I have several small tumbler machines but no drums for them. I will surly order my drums from you again. And peruse your site for more good deals.. thanks very happy customer!

I liked it because it is the same depth but smaller in diameter. I got it to use for stage 3 & 4. For two reasons, this stage of your tumble your rocks are a lot smaller so smaller tumbler means don’t need to put in a lot of filler to get your 2/3 reds full. And it also means the grit from stages 1 & 2 is a lot heavier so for a better finish using a cleaner tumbler that has not been used with these grits. By using the smaller tumbler only for stage 3 & 4 will give a better shine
