SI FANG 5Pcs 60mm Diamond Cutting Disc Cut Off Wheels with 5Pcs Mandrel 1/8'' Shank Stone Blade for Rotary Tool Drill Attachment Cutting Discs Polishing Glass Tiles Marble Plastic Jade (2.4in)

These are made to tackle larger cutting jobs than the diamond wheels that are usually included in rotary tool assortment kits. They work really well, but it's important to ensure that everything is well secured or it will wobble and make a bad cut.

This was a fantastic tool that exceeded my expectations. None of my other dremel style tool bits could get the job done. Used it for cutting 1/2" scale bricks and concrete blocks. Cuts like butter. If you get this tool, definitely use safety glasses!!

Took about 20 minutes to cut through a 3/4 inch thick clear quartz crystal. But it got the job done. Cutting through hard stone is not easy.

I was looking for a quick, inexpensive solution to cut a handful (6 or 7) of ceramic tiles for a backsplash. This worked perfectly!I attached the bit directly to my high-speed hand drill, clamped each tile to a scrap piece of wood and simply cut along the lines I marked. A couple pieces required several cuts to shape around my outlet. I cut all of my pieces using just one wheel, but did notice some dulling by the end.Not a great solution for big projects, but if you have 20 or less tiles this is perfect.

Good size cutting wheels and they cut reasonably fast and leave a clean line in porcelain. The issue I have it the metal they are stamped out of is remarkably flimsy making cutting a straight line a real challenge. If it was not for that I would be giving them a better rating

Has more diamond dust that my others, would buy again if ever needed

At medium rpm, just spinning, not actually cutting any product yet - the shaft broke sending the disc flying. Incredibly unsafe product.

These are wonderful. They cut rocks and stone very well. I will buy these again, and I recommend them.
