Dremel 545 7/8" Diamond Cut Off Wheel Rotary Tool Accessory for Brick, Concrete, Epoxies Porcelain, Ceramics and Marble

I used this tool for scoring, cutting, and sanding tile edges and it worked great! It completely exceeded my expectations. It came in so handy for detailed cuts I was making for a mountain mosaic for my kitchen backsplash. It was also super helpful for creating rounded cuts. Its durability has been great, too! Not only did it provide me the ability to do great detailed work but it is still going strong and is ready for my next project. I used it at 10k rpm with no water and never saw the glowing red or deformity that some people talk about. Would not have wanted to do my project without it.

[This review was collected as part of a promotion.] Mine are EZ-Lock 1 1/2"ers, instead of 1", but I'll tell you this, they'll cut through nickel (the metal, not the coin, which is harder than regular steel) when the fiberglass reinforced cutting wheels just won't anymore & start powder/"vaporizing" into dust. I know this 'cause they're what I wound up having to use when fabricating my own custom sized diamond stones from stock sized ones & that's what happened, & they're what I needed to be able to finish the "project", glad I got 'em or I would've wound up having to wait another week or 2 for some to arrive! To sum it up, these are the most hard-core cutting wheels they make. If these don't work, you might need an angle edge grinder..., #100 !
