DEWALT20V MAX* XR Cordless Polisher, Variable-Speed, Random Orbit, 5-Inch, Tool Only (DCM848B)

This is an amazing polisher! The caveat is that it is VERY heavy with a proper battery---so heavy that I only use it on the top panels of anything I work on. If you're a body builder, you might be able to fully cut a couple cars with it, but for me, it's strictly a hood/roof/trunk top polisher.Quality - This is in top-end territory for performance and overall quality, easily matching the top-end polishers from rupes et al. Plus, you're buying a tool from a company that actually knows how to make tools. Yea! I have no doubt it will last as long as you want it to. I've run over many of my Dewalt XT tools before with my truck and they keep on keeping on.Batteries - If you're looking at buying this and are not already invested in Dewalt batteries, plan on spending at least $160 on a couple of 6AH batteries. The 5AH batteries work, but will only run around 45 minutes each. The 6AH ones perform much better, you can expect over an hour out of those. Since I only use this on the top panels, 2 6AH are more than I need to finish a car. If you're planning on using it for the whole car, you're going to need more than 2 6AHs for a mow down, and even more if you're going 2-stage.Overall - This is going to be a game changer for most detailers. The weight actually helps on the top panels, I find it to be the perfect amount of pressure and can just steer it around. Not having to worry about the cord is worth it, along with the huge benefit of having something that doesn't require electricity for remote quick defect removal. It's an excellent tool, but I highly recommend that you have a lighter, plug in DA for the sides in addition to this. It's just too heavy to be your only DA IMO. If you're a pro detailer, just buy it already. It's a complete game changer.

I have bought other less expensive and smaller polishers and they fail when pushed, but this has the power to not bog down, plus its variable speed offers the best combo! It's well balanced and not that heavy to support long work usage! For a battery portable it lasts a long time and convenient not to worry about a cord trailing behind!

I was looking for a polisher for my car and this came to mind. I already have a 5Ah battery and charger so I only needed the tool. Going cordless is great, hard to put into words but you can move faster around a car. When using a corded tool I find the cord is always getting stuck under a tire or something. If you set the cord over the car hood or roof it tends to mark the surface or create light scratches. Which is not a big deal but when polishing a car you are trying to remove scratches.The polishing action is good, I get a great shine using this Polisher. There are a couple negatives, first the polishing pad is 5 inches. That is an odd size, I could not find this size anywhere. Amazon has some 6" pads that they say work on the 5" plates. DeWalt did not have anything available. I tried the 6" pads and they work.The second negative, the pad is too large for polishing all parts of a car. It is difficult to get under the door handle of the car. This is a place where you need a polisher because that area gets scratched. I found you need a second smaller polisher for detailing a car. Some areas of a car can be hand polished but after you see the results of a power polisher you will want more than hand polishing can deliver. But one of those buffing tips for a drill may be sufficient to use in combination with this polisher.The polisher is slow enough to do a good job and not burn through the paint. The speed is variable but I typically use the slowest speed. The results vs hand polishing are substantial. You will polish a car like you have never before by hand. It is amazing and fast. The 5Ah battery lasted the entire car with some battery left. You might need two batteries if doing a large truck but one should work for most cars.

I used this machine for the first time on my car today and I am very happy with it's performance.It has plenty of power, it runs pretty smooth, seems to be well balanced and just the right weight.It is a bit beefy but easy to control, the only little thing I found that was a little off and I hope they correct that in their next version would be a little more clearance between the battery and the vehicle when working in certain areas and contours. just keep that in mind because it can scuff the paint.

I used this machine to buff out some heavy scratches but mostly light scratches and swirl marks. I prepared my SAV for a nano ceramic coating. It’s heavy with a 4 amp hour battery. The trigger is sensitive and can accidentally turn on. The rotary speed dial is perfectly placed and gives plenty of control. I used this on a 2021 BMW X6M. I think I used 4 or 5 batteries to do the whole car over a couple of days. I already had the batteries so this wasn’t a big deal for me. I used a variety of pads: Eurofiber Microfiber, microfiber, and chemical guys sponge pads. It got the job done! For what it is I think it’s a little expensive but maybe I’ll use it again on my family or friends cars. This is the only cordless RO machine I’ve ever used so I can’t compare

Was worried about the weight and if this would actually work better than the advertised car polishers. Since I have the Dewalt batteries and chargers already I took the chance. No issues with weight or bulk and works like a charm. Polishing the cars takes a fraction of the time it used to.
