Review on 📦 MIDO Pro Abrasive Flap Discs, 4.5 Inch, 20 Pack, Assorted Grit 40 60 80 120, Aluminum Oxide Sanding Grinding Wheels, 4.5 x 7/8 Inch, Flat Type #27 by David Carmody

I bought it, like many people, without expecting much. They seemed to work fine, but the problem is that the mounting base is too flimsy. I have a Metabo HPT angle grinder and when I installed these discs they spun after installation. I tried tightening it more, but the tool was MAXIMUM tightened and the disc was free to rotate in the mount. I was in a bind and needed to use them so I kept working, they did their job but every once in a while they made an awful noise. I guess because they were so lost they started vibrating. That made me nervous because the last thing I needed was for that disc to fall apart at 10,000 rpm and the disc material tossing through the air like shrapnel. I go back.
