> 3 dayThese do the job but I have no idea how long they will last. One thing I noted immediately was any paint they come in contact with will clog the cutting surface and must be scrapped off to continue.

> 3 dayI had to make some spacers to get them on a very old makita side grinder and remove the safety guard but they worked great. Safety shield and heavy gloves an absolute must!

> 3 dayThe embedded diamonds are spars and straite the concrete as you grind it. If youre just rough grinding, and dont need them to last very long, these work well enough.

> 3 dayWhat I like about this 4” grinder disc is, it fits perfect on the 4 1/2 grinder. I used the disc to clean up old grout and tile adhesive. Cleans up excellent. I live in Puerto Rico and got it in a week.
