Split Grade 120/220 - Perfect for the second step in a rotary rock tumbler.
Silicon carbide tumbling abrasives have sharp edges ideal for use in tumbling barrels for 'sanding' edges and softening burrs. Great for rounding off rocks. Also, parts can be self-tumbled with this rock tumbler grit when aggressive deburring, scale removal and edge rounding is required. Silicon carbide grit for rock polishing will resist fracturing, allowing for extended tumbling cycles or multi-batch uses with excellent results.
