Review on Grinding Grinders Polisher Concrete Accessories by Brad Schaefer

Barely fits Ryobi and does not fit Milwaukee at all. If it matches your tool, it will probably work well enough to get the job done. I originally bought this for a new Ryobi coffee grinder. The tool was defective and almost caught fire after 3 minutes of use, damaging this device as well. I traded it in for a Milwaukee and it didn't fit at all. And it was damaged so I spent my money on it. It worked even though I used Ryobi for 3 minutes.
