Product Description

This is a no-nonsense grit kit for polishing all kinds of rocks. The first three stages are different grades of silicon carbide, and the polish is aluminum oxide.

There are four levels of grit included in the kit (or available individually):

  1. Step 1 - 60/90 Grit Coarse (670g) - 500ml Bottle
  2. Step 2 - 220 Grit Medium (330g) - 250ml Bottle
  3. Step 3 - 600 Grit Fine (330g) - 250ml Bottle
  4. Step 4 - Sub-Micron (>14,000 Grit) Polish (180g) - 250ml Bottle

Now available in quarts (975ml containers)! These are a great value for those looking to tumble lots of rock!

We include larger bottles of coarse grit because we find that most rocks benefit from two cycles on Step 1. There's enough here to polish up to 9lbs of tumbling rough.

Here's our favourite recipe for most rocks:

Week Grit Tbsp/lb of rock Water level
1 Step 1 2 Cover top of rocks
2 Step 1 2 Cover top of rocks
3 Step 2 2 Just below top of rocks
4 Step 3 2 Just below top of rocks
5 Step 4 2 Just below top of rocks
Clean your barrel and rocks between each step of the tumbling process.
