2 LB Coarse 60/90 Silicon Carbide Grit, Rock Tumbler Media Grit Refill, Rock Refill Grit Abrasive Media Step 1

Good product. Rock tumbling grit in general is expensive, and you cannot reuse. This product is inexpensive and gives great polishing results.

Does the job, nice shaping.

Necessary product for polishing rocks. Expensive but necessary in the process. Product is a good size and should last me several months

Great value for step 1 but open the container outside because the bag inside is terribly cheap and was torn and made a mess

I made a knife sharpening stone out of it larger than an ordinary brick for machetes using pure cement, grit, and water. It grinds even hard knives quickly. Real SIC

The stuff works great I'm much happier with the 8 lb bulk

Perfect

This grit was just what I was looking for. I have a bunch of big garnets with poor crystal faces to grind into spherical shapes and it will require multiple runs through my 1 gallon tumbler. This 10 pound lot of grit was priced very well per pound compared to smaller quantities offered by other vendors.

Very consistent particle size, making it suitable for optical work. I used this successfully when grinding telescope mirrors, where consistent particle size is very important. Very satisfied!

I have tried and used other step 3 polishes and this type seems very good as a pre polish. I will be buying more.

Pretty good! Been using this grit. Definitely great to have a large amount of this as a hobbyist.

Worked great for my mini glass maker drum

The grit is excellent in both value and quality, but for whatever reason, the lid of the tub is incredibly difficult to open on first open. I don't reseal it as it is so difficult to open.
