Didn't fit any of my grinders: DeWalt, Milwaukee, Makita, DeWalt 60 volt or 20 volt. This will likely fit small grinders, not the ones I own. The profile is too high to prevent the wheel from touching the ground, adding a washer on the back didn't help as it's too higher than the threads on the shaft, the height is fixed: any other cover that I own (Makita, Dust Free Productions) is at least 1/4 inch, I set the wheel at the level of the brush and when you place it on the surface it has room to push the wheel down. In this case you will probably have to break the brushes to lower the wheel to touch the grinding surface, which doesn't make sense to me, (I see many others with the same design that I hadn't looked at before, with good branded cases I think flooded) The plastic itself looks high quality I think I liked the look and tried my best to make sure I could use it, tried it on all the grinders I had but found that it wouldn't be enough for me, so I went back and ordered 2 Makita once.
