500 Aluminum Oxide Grit: 5lbs

Shipped fast, wide selection, and very high quality products. I will always order my accessories from Rock Shed

I recently switched to AO for stage three of rock tumbling (this product) from silicon carbide 600 grit and I'm glad I did. I use a vibratory tumbler for stages 2-4, and so require much less abrasive, and time, than with a rotary tumbler. This product, compared to SiC, gives a superior pre-polish to the point I could almost get away without further tumbling- almost. I am using microalumina for polishing in lieu of standard grade cerium and here, too, I am getting superior results. Give this technique a try. You should also know that the Rock Shed is a long-established lapidary supplier with reasonable pricing. Check out their website.

This is the best tumbling media.. Rock Shed products are the best. Do not buy cheap grit...buy the best!

My grit arrived super fast, double bagged and in a sturdy box. And it works great!!

Great product, great price. Does what it's supposed to do. No frills packaging.
