Kingsley North Large Grit & Polish Pack for Large Rotary Tumblers with 35/70, 120/220, 500 AO & 22,000 Grit Micro Alumina (Aluminum Oxide) Polish

Looking for a large grit and polish pack for standard size barrels? Click here.

This 4-step Kingsley North Large Grit and Polish Pack for Large Rotary Tumblers is intended for large rotary tumblers that have 6+ lb sized barrels. It replaces the 60/90 silicon carbide commonly used on the first stage with 35/70 silicon carbide grit.

In large barrels, the 35/70 is more efficient: the added weight of a large barrel load keeps the coarser grit particles in constant contact with the rocks, resulting in an optimum combo for faster material removal and shaping, particularly with harder rocks like agates and jaspers.

Includes:

• Stage 1 (Extra Coarse): 5 lbs of 35/70 Silicon Carbide
• Stage 2 (Medium): 5 lbs of 120/220 Silicon Carbide
• Stage 3 (Pre-Polish): 5 lbs of 500 Aluminum Oxide
• Stage 4 (Polish): 3 lbs of 22,000 Grit Micro Alumina (Aluminum Oxide) Polish
