## Description

2 Pounds of 60/90 Grit Silicon CarbideComes with FREE Polishing InstructionsWe use a superior blend of Green/Black Silicon Carbide for our first stage. Green Silicon Carbide is of higher purity than Black Silicon Carbide, therefore it will work faster than Black Silicon Carbide because it's harder and stays sharper longer.We have a large selection of heavy duty tumblers. We offer a full range of silicon carbide grit (36, 60/90, 120/220, 400/600, 1200 and 1500) and aluminum oxide (400/600, 1200, 1500 and 12000). These can be purchased individually in any weight denomination that fits your needs or we have pre-made kits for your specific size tumbler. We have kits available with or without plastic pellets.

## Questions & Answers

**Q: All of my rocks are beach tumbled. Can I use just stage 3 and 4 to make them shiny. Do I need anything else?**
A: Yes!  I’ve done this and these 2 tumbles resulted in smooth and shiny rocks

**Q: Why does this grit have two numbers? Is it two sizes of grit mixed together? That would seem pointless,**
A: It is a mixture.

**Q: How many loads can you get out of the 2lb bag typically?**
A: I use 3 tbs of grit per tumbler.  You will have to do the math and figure out how many tablespoons per pound then multiply by 2.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value for money
*by C***Y on 14 November 2023*

No 3 grit for tumbling. works very well.

### ⭐ False item description
*by I***N on 10 June 2024*

This is sold as polish. It is not polish. So t buy this if you are looking for something to polish your stones with. Waste of money.
