Power, portability and comfort is excellent with the Milwaukee M12 polisher. Navigating around headlights, pillar posts and wheel-openings is a breeze with the Milwaukee M12 polisher and sander. This will help any detailer get more work done with less effort.

Overall Score 8.7 (out of 10)

Detailing cars is not always about hoods, trunks (bonnets and boots for our UK friends) and other large areas. There are many areas that would typically require hand rubbing/polishing because the five or six-inch pad of the polisher won’t fit. These areas are a great fit for the Milwaukee cordless polisher sander. This polisher is part of Milwaukee’s M12 line (12V) helping keep the tool small and portable.

M12 Milwaukee Cordless Polisher Sander Features

The M12 Milwaukee cordless polisher sander comes with a 3-inch foam and 3-inch wool pad, so we can easily machine-polish pillar posts and mirrors. Headlights can now be polished without taping off the surrounding areas (care must be taken), which saves valuable time. Plenty of power is available when the trigger is pulled, regardless of the product that fills the pad, and the 12V RedLithium batteries fuel the powerful motor. Run-time with the 12V batteries is good, so you should be able t complete the job without a recharge.

Milwaukee did a great job engineering the M12 cordless polisher in terms of comfort and feel-in-the-hand (ergonomics is the word used nowadays). The M12 feels very balanced in the hand, almost perfectly. With the extended use 12V battery, the M12 polisher seems almost weight-neutral, therefore it’s very easy to navigate the polisher where you want it to go. At only 5-inches long, ducking under wheel-wells and working around door jambs becomes simple with the M12.

Power, portability, and comfort are excellent with the Milwaukee M12 polisher. If there is one area that could use some help, it would be with the battery and/or power consumption. From my knowledge with other power tools, it would seem that a brushless motor would greatly aid in battery performance. Don’t get me wrong, one battery will get you through a vehicle without a problem—just not the whole day. I don’t have any hesitation recommending the Milwaukee M12 cordless polisher sander for getting more work done with less effort.

It’s a nice tool but I agree with John, I wanted to use it as a wire brush tool and a cleaning brush for my tires but getting something to adapt to the M9 threads is basically impossible. I’m tempted to try to tap it out to something standard.

John Henderson

I have one of these, it works great but the arbor threads of the tool are oddball, so you have to always get the Milwaukee backing plate which is hard to find and expensive
