Milwaukee M12 Variable Speed Polisher – Sander

Milwaukee M12 Variable Speed Polisher - Sander

When the news about the new Milwaukee M12 Variable Speed Polisher – Sander, I took a quick look at the picture and realized that many people might wonder, “Why not just use a drill with the polishing and sanding heads?”  One look at the specs, specifically the RPM’s that the M12 runs will tell you just how much different it is from a drill.


With that realization, you have to take your  expectations of how you think about power tools and be completely open minded. I have an M18 Fuel Impact Driver that I can run for what seems like all day without stopping to recharge it. With the M12 Variable Speed Polisher – Sander, you can expect to get a full pass on the exterior trim. This may not seem like much to those of us using Milwaukee’s drill/drivers, but that kind of run time wasn’t possible in a cordless polisher before now according to Milwaukee.

“As the most compact cordless polisher on the market, the M12 Polisher/Sander is the perfect complement to a full size polisher for a faster finish,” says Andrew Plowman, Group Product Manager for Milwaukee Tool. “In our field research with this tool, we found that automotive detailers were saving up to 20% of their detail time by going over small/thin/curved surfaces with the M12™ Polisher before coming back through to cover larger surfaces with a traditional full size polisher. By simply adding this step with the new Milwaukee product, the user could service another car every few days, ultimately getting a full return on their investment in less than three weeks.”

Milwaukee also tells us that the performance of the M12 Variable Speed Polisher – Sander is up with the pneumatic tools normally used. Obviously, the convenience of not being attached to a hose and compressor is attractive. The variable speed trigger and compact size allow the user to have excellent control in those smaller areas that they are working on a vehicle’s exterior. Accessories can be change with no need for a tool to make the switch.
