The vacuum brazed diamond drum wheels are designed for making an inside circle, oval, or arc. The tool features the fastest material removal rate of any grinding drum when used on granite, marble, concrete and engineered stone. 30/40 grit diamond (coarse) for grinding hard granite. 70/80 grit diamond(medium) for grinding medium/soft granite and marble. 5/8-11 thread fits most grinders, 2" diameter and 2" height.

For harder stones, we would recommend you to use a P2 (Position 2) diamond grinding drum wheel with medium grit after the P1 (Position 1) diamond grinding drum wheel coarse grit to get a better even surface start before polishing. This will also prolong the lifetime of polishing drum wheels.

You may buy seperately our adapter 5/8"-11 to M14 to use with power tools with M14 thread spindle.
