14 inch diameter machined electroplated steel diamond grinding discs that attaches to a potters wheel like a bat. Both sides of the thin discs have a diamond grinding surface, one medium/coarse (120 grit), and the other fine (400 grit).
Just flip the disc over to change grits. Both sides are separately replaceable. Use with water. 300+ square inches of total grinding area, two 14" discs back to back, combined as one.
It works like a slower speed lapping disc or lap grinder, and can be used to smooth gemstones and glass and sharpen tools. No assembly, it is ready to use. Works for high fired porcelain, stoneware or bisque.
Each disc is machined flat before electroplating for an even, very effective operation, and evenly distributed consistent grit particle size. Electroplated diamond tools vary wildly in quality. These are guaranteed to be the highest professional quality.
Use only the included special low-head bat pins to attach the disc to the potter's wheel . Regular bat pins will stick up above the surface. There is an additional option of a 12" X 1/8" plastic bat that raises the height of our discs if you prefer to use your existing bat pins.
