Review on 545 Diamond Cutting Wheel Set (22mm) - 25pcs with 402 Mandrel (3mm) - 5pcs and Screwdriver: Ideal for Rotary Tools by Rob Sanchez

It helped! I bought an expensive glass drill and it didn't dent the porcelain stoneware at all! For a few dollars more I got 20 diamond wheels, 5 shafts and a tiny screwdriver to connect the wheel to the shaft. I wasn't sure if this would work for my job but after reading a lot of great reviews I decided to order it. it was almost like cutting soft butter with these wheels! So happy to finally have the wall panels back on my kitchen walls. I only used one blade for about 20 cuts that I had to insert into the tile to screw on the bezel. Got them in a day or two with PRIME. We'll have to come up with new designs to use the other 19 remaining blades. Ha! I highly recommend these diamond discs!
