Fundamental Rockhound Products: 3 lb 46/70 Extra Coarse GRIT for rock tumbling polishing Silicon Carbide

I use this for rocks that have thick sediment on it. Works well so far. I keep checking rocks a few times a day in the rotary tumbler to see progress.

I am going to give this 5 stars but it didn't work for what I purchased it for. I bought this to try and tumble sand small wooden parts. This was not coarse enough for my purposes, so if you are buying this for that purpose, please reconsider. But as for a good review I can say it does have little dust, very consistent in its particles. When I was using this to dry tumble (which I don't believe it is intended for) it does powder up pretty quickly.

I did the silicone carbide grip thing on my G34. This was perfect!

Worked good didn't have to tumble as long

Does as described.
