    Grinding disc

    Love this item. My mugs and some bowls are all stable and neat in 1 minute. Love this. Made my wheel thrown life easier.

    Great, Solid Product!

    This is a great set of grinding bats. Literally cuts your work in half and looks wonderful.

    Saves so many mugs and it’s so easy!

    I use porcelain clay so the 120 grit is perfect for leveling mug bottoms and smoothing them out. It takes less than a minute per mug, and then I go in with a 400 grit flex pad afterwards to finish. I get so many complements about my smooth mug bottoms from my customers!

    Best and easiest

    Until I found Diamondcore Tools, I used to shop a lot of hardware stores and automotive stores trying to find what I needed to fix my problems . You guys have made it so easy, being a pottery shop as well the tool guys to fix our problems. I love the sanding disc! Makes life so much easier when I don’t have to completely trash a piece because of the glaze running. Using a grinding wheel sometimes makes the whole chunk come off. That just ruined the piece. You make my world a whole lot better. Thank you. Everything I have ordered works exactly like you say it will. No issues with anything I’ve purchased. Love it all!

    Excellent grinder bats set !!!

    Easy to mount on the wheel with bat-pins, either 9” or 10” pin spacing, and switching bats to change grit is simple. At fastest wheel speed, and a copious amount of water to eliminate clogging of the diamond grits, these grinder bats truly do a wonderful job of flattening a bottom, rounding bottom edges, or cutting away glaze drips. Cleanup is easy with water and a stiff bristle brush. I am so impressed with their function !!! Thank you Diamond Core for having these 👍
