This is one of three 8″ buffing wheels I got off Amazon. The pictures I saw seemed to imply that they could be used with an angle grinder – 11000 rpm.
Hard to tell, but the whee looks really nice after a buffing with the course wheel and brown compound then the medium wheel and green compound. When I went to do the final buffing with the soft wheel and red compound…disaster.
The wheel disintegrated before I even got to apply the red compound. Reading the fine print I realized that the wheels were meant only from buffers with a speed of around 3000 rpm. The two other wheels must be made well to have stood the almost triple speed I was using – yikes!
I picked up a used Craftsman two speed buffer and that worked well on low speed with the blue (course) and yellow (medium) wheels. I ended up using course compound and the course wheel to take away all the corrosion and the yellow wheel with green medium to fine compound to bring them to a shine. I’m not trying to get a super shine or to the point they are concours. I’m happy with excellent drivers and good for local car shows. The two pictured were the worst of the set and they look just nice. Now I need to find $100 to get them mounted and balanced!
