This is my honest review. Please let me know if you find this helpfulNot for all angle grinders - Be very aware before purchase that this has a 20mm arbor hole. I made the mistake of assuming it would fit my angle grinder since it is shown several times being used with one. I have 4 different brands and it doesn't fit any of those. I'm clearly missing its intended purpose or am unaware of an unusually sized angle grinder. I am not decreasing the rating over this fact, since I did not take the time to measure my angle grinder for proper fitment. I ended up modifying this wheel by increasing the arbor hole to 7/8" so that I could further test its capabilities.So what is it good at? - It's fairly good at a lot of things, and great at cutting any variation of wood, plastic, pvc, or fiberglass, with an occasional bit of metal. This is not advertised for metal, but I've found it can handle at least some with no issue. And because it lacks big teeth, this isn't something you have to worry so much about ripping soft materials apart on contact rather than making a clean cutting. It probably clogs less than a standard abrasive wheel seeing as that the abrasive cutting particles are much sharper and further apart from each other and they stick out the side of the wheel rather than having a uniform surface. This could also potentially minimize binding within a cut. It will also never reduce in size as you cut. It did clog somewhat during my use as you can see in the pictures but it kept going at a little slower rate. When I cut through some thin galvanized metal it quickly stripped off all the junk that clung to it and began cutting everything fast again.Lets face it, there are probably much better cutters for any one job you can think of if you are doing a whole lot of one type of cutting. But I think the benefit of this wheel is that it's rather versatile. I could see myself possibly using this to cut up objects that are composed of multiple materials. Or cutting in tight spaces or where I'm worried about a wood blade getting damaged by excessive nails. I'd probably love this on something cordless if I was a plumber or I had a job doing renovations involving various home demolition. As a general handy do-it-myselfer, I'll probably just leave it on a tool when I have no idea what might need a quick notch or cut on my next small project or repair.
