This 4-step Kingsley North Grit and Polish Essentials Pack with 600 SC & 22,000 Grit Aluminum Oxide Polish contains 1 lb of 60/90 silicon carbide, 1 lb of 120/220 silicon carbide, .67 lb of 600 silicon carbide, and .5 lb of micro alumina (22,000 grit aluminum oxide) polish. Designed for rotary tumblers, tumbles 8–10 pounds of stone.
Each stage is portioned according to how much material is typically used during tumbling. The finer pre-polish and polish steps require less grit by weight, and the included amounts are sized to match the typical consumption rate for a full batch. This ensures efficient, balanced performance across all four stages.
