These machine buffs and sanding discs are exactly what we use here at Evan's Detailing and Polishing. The buffs and sanding discs pair well with the JEM wheel machine that we helped design and build. If you own a wheel machine that runs a 1-1/4" arbor these will fit.
This setup will help reduce the rounding of the holes and is a safer alternative to achieving a better shine.
If you are looking for the smaller buffs for the grinders check out our selection here.
