About this item
Product details
Uncover the shining potential of your gemstones
Our comprehensive rock tumbler grit kit supplies all the tumbling grit you'll need to go from rough rocks to polished gemstones
- 1 pound, step one coarse rock tumbler grit
- 1 pound, step two medium rock tumbler grit
- 0.5 pound, step three pre-polish grit
- 0.5 pound, step four final rock polish grit
- 1.5 Pounds of ceramic filler media
- Instructions manual
Get professional quality results
Our superior grade silicone carbide and aluminium oxide polish produce fantastic results and are used by avid rock tumblers all over the USA and Canada. We also have many rock tumbler grit and polish refill products available for when you run out of grit.
Includes 1.5lbs of ceramic filler media
This combination-package includes 1.5 pounds of Polly Plastics ceramic cylinders for protecting and cushioning fragile stones while tumbling. These small, angle-cut cylinders help fill gaps between rocks so your load tumbles with a smoother action. This improves the grinding and polishing in the rotating barrel and helps prevent your stones from being bruised.
Each grit in our rock tumbling grit kit has a different purpose:
Step 1 (Coarse): This stage knocks down all the rough surfaces and reshapes your rocks into more round-looking stones.
Step 2 (Medium): This grit also helps remove any scratches, cracks, or dimples on the surface.
Step 3 (Pre-polish): This grit will completely smooth out the rocks but won't give them a high shine.
Step 4 (Polish): This grit gives your rocks a dazzling shine and a beautiful finish.
Important: Grit is sold by weight, according to how much is needed in each step. Steps 1 & 2 are 1 lb. each and Steps 3 & 4 are ½ lb. each but all are sold in the same size jars for packaging consistency. The different weights, along with different densities, will mean that jars will not have equal amounts of fullness.

- PUT A DAZZLING POLISH ON YOUR ROCKS with Polly Plastics rock tumbler grit and polish refill. Our one-of-a-kind rock polisher kit contains four different kinds of grits to provide initial shaping, smoothen the rock surface, pre-polish the rocks and finally polish the rocks for a professional-looking finish. Great for kids and adults alike.
- PACKAGE INCLUDES - 1 lb. 60/90 coarse silicon carbide grit, 1 lb. 180/220 medium silicon carbide grit, ½ lb. 500 fine silicon carbide, ½ lb 1200 aluminum oxide polish, 1.5 lbs. non-abrasive ceramic filler cylinders and an easy-to-follow instructions manual. Polly Plastics also have 2-pack grit and polish refills available for each stage of the rock tumbling process, refills of our ceramic media and many more rock tumbling products. Check out our storefront.
- GRIT SOLD BY WEIGHT NEEDED FOR EACH STEP – Steps 1 & 2 are 1 lb. each and steps 3 & 4 are ½ lb. each, but all are sold in the same size jars for packaging consistency. The different weights, along with different densities, will mean that jars of rock tumbling grit will not have equal amounts of fullness.
- CERAMIC FILLER MEDIA to cushion soft, delicate and brittle rocks: Ensure your precious stones remain unscathed while tumbling. This tumbling grit kit includes 1.5 pounds of small, angle-cut ceramic rock tumbler media that fill gaps between rocks to protect and pillow your rocks during tumbling - a great alternative to plastic pellets. The ceramic filling media can be washed and reused over and over.
- WORKS WITH ALL ROCK TUMBLERS - For ease of use and convenience, our rock tumbling grits work with all brands of tumbler. Our rock tumbler grit and polish kit is ideal for use in a 5 lb. tumbler or five 3 lb. tumblers. Premium rock polishing grit kit - Made in the USA.

The only bad thing is the porcelain pellets, I'll use rubber ones next time. They broke up my softer stones.
