  1. professional finish! 5 Star Review

    This grinding wheel is fabulous! It allows me to take my ceramic sculptures to the next level of professional finish. I can now smooth the bases so that they are satin smooth and sit perfectly level on a table or pedestal. Best of all, I can totally smooth out any surface where the glaze ran. I love how glazes can run together and blend, creating new colors and patterns but the excessive drips were a total pain to remove. This grinding disk has certainly made my life easier and makes my work much more appealing to close scrutiny.

    I've only had the chance to try the 100 grit so far, but I'm in love with this product! It works incredibly well and for being double sided with replaceable discs, it's a great price! I appreciate that they show you how to maintain and stretch the lifespan of the discs, it's very honest and helpful. Really glad I found this before buying from another company.

    Very good product. I ordered the complete kit last year and I use it regularly. Really useful. I ordered a new disk this year because I use it very often, I save a lot of time with these disks. Very efficient service also.
