Product Description

"Tumbler grit" is a silicon carbide powder that is much harder than the types of rocks that are commonly tumbled. If it is tumbled in a barrel with rock and water the abrasion caused by the grit particles rounds the sharp edges off of the rocks. We use about four tablespoons of grit in a three-pound capacity tumbler barrel..


Use this grit that most people use for STEP 2 of the rock tumbling process. It is an ungraded 120/220 mesh silicon carbide powder. In a rotary tumbler we use about four tablespoons of medium grit for every three pounds of barrel capacity.


Caution: Do not dispose of used grit, polish or rock slurry down a drain.
