This is a 12-inch or a 14-inch diameter electroplated diamond grinding disc with the face completely covered with diamonds. The 12" has 110 square inches of grinding surface, the 14 " has 150 square inches of grinding surface.
Attaches directly to a potter's wheel with standard low head bat pins (included), 10" on center.
Ready to attach to your wheel and work, no assembly except to put the bat pins on the wheel. Medium to coarse grind, #120 grit for easy removal of material.
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 with water.
Low profile to keep swarf (grinding water and material) in the splash pan of the potter's wheel. 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" pottery bat that will raise the height of the disc if you prefer to use your existing bat pins, https://www.etsystudio.com/listing/604418811/12-inch-x-18-inch-pottery-bat?
This disc works so well. I was able to save about 8 pieces of pottery that had a wobble to them as a result of warping. The disc arrived in about 2 days. Great item and great seller!
