Split Grade 60/90 - Perfect for the first 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 silicon carbide tumbling grit when aggressive deburring, scale removal and edge rounding is required. Silicon carbide deburring grit will resist fracturing, allowing for extended tumbling cycles or multi-batch uses with excellent results.
