Milwaukee Grinder
I had the Grinder for a long time. The gear housing stop was broken. I found the parts on eReplacements Parts. Also replaced some of the other parts that were starting to wear out and everything fits.
Would have given a 5 Star but when I requested additional info on the website regarding the parts if these were correct or not no one ever returned my e-mail.
