Query: Works good

I bought about 6 of these cutting wheels to cut my window wells down. They were sticking up way too high and I needed something to cut them. I decided to use my rotozip with this wheel and it worked fine. The wheels did seem to wear down fairly quickly, but I was cutting fairly sturdy metal. I then used it to cut wire shelving and it worked great on that with not much wear.For some reason, these wheels are hard to find which is why I used Amazon.
