The Wet Diamond Polishing Drum Wheels are designed for wet polishing of sink cutouts or tight radius. A complete set usually comes with grit 50,100, 200,400, 800, 1500 & 3000. Polish from grit 50 to 3000 respectively.

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 of polishing drum wheels.

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