I am not sure if thats the right term, I have a sander, buffer, grinder 7 inch from harborfreight, I use the sanding pad some times, and I have used metal grinding discs etc with the screw on setup, I found some 7 inch metalworking discs for it on sale and bought them, not realizing they don't have threaded insert, you need the collet/nut that clamps them in place, is this something you can buy to use with the grinder? or do you need to buy a specific grinder that has one?
