It originally comes with the velcro pad for the buffing/polishing pads a roloc adapter. Problem is stupid Milwaukee used an uncommon M9x.75 thread size which might as well be proprietary in my book. Other brands use a standard/more common 5/16-24 spindle thread. So to buy the M9 roloc adapter or original accessories pack is stupid expensive.
But there are aftermarket adapters. I bought this one for a different use but it has a 1/4-20 thread so you can use any common roloc adapter (like the one you have pictured) with it.
I use mine for buffing/polishing. I use the M12 right angle die grinder for roloc dics. I tried to use the RA die grinder for polishing/buffing but it spins way too fast & not enough torque. That's why I ended up buying the M12 polisher/sander. It will work ok for roloc stuff but the M12 RA grinder works much better for roloc accessories & better ergonomic IMO.
