DeWalt DCM848P2: homedepot.sjv.io/QqdoP
Powered by the DeWalt 20V platform, this Brushless polisher doesn't lack on power. In fact, in our 23-polisher shootout recently, it took 3rd-place in the Cordless division, finishing just behind two very stout Flex machines.
Check out the full Orbital Polisher shootout.

*Good **MyBest.Tools** power and rpm control.*
Nice video. Been using this tool for 3 months. I keep 6 battiers 5 Amps. I do a lots of paint corrections, polish and sealers. Works well for me. Just bought Ryobi cordless DA. Planning to use only for quick polish, wax and sealers.
I just used it to cut a few pieces of plywood boards th-cam.com/users/postUgkxqqoaX03nrziKwF7Bjjcc71YzLEleMvOS works great. The blade that came with it isn't very good and I bought a much better bosch one which made much cleaner cuts. Blades were cheap, a few bucks.
As a current prestige Euro car detailer who’s beginnings were restricted to the safety of a DA, I got this machine after being enticed by the cordless factor but have since found its only use is finishing & waxing - I tend to use if for the latter - is supremely quick & easy to apply wax but it’s basically about as effective as baby wipes when it comes to anything more. Round the same time as buying the Dewalt I also got a corded Makita DA with forced rotation but pretty much use that exclusively for a brush attachment tool to clean carpets n floor mats. That’s because after going through the hard yards of learning how to use a rotary in a paint n panel business (change of work thanks to COVID), I kind of feel from my experiences that you can’t go past the efficiency of a solid rotary. Others might feel differently but I hope my 2 cents can save others a few hundred bucks, unlike me (though I got it all refunded back as taxable expenses anyway).
Since departing paint n panel & returning back as a prestige Euro detailer, I pretty much use a rotary for cutting with a wool pad, rotary + soft pad for finishing with the relative compound/s, small pistol Milwaukee polisher for scuffed window trims/etc & use the Dewalt cordless as a sealant wax applicator.
What kind of polish are you using?
Excellent video, very informative 👍
Think going to wait on the new Milwaukee Polishers so I can use the same batteries with their other tools. Great stuff and well done.
Thank you for the informative video. Does this polisher use standard polishing pads/discs? Or does need brand specific polishing pads/discs?
Thanks for the vid. Can it be used for DA sanding as well?
Were can you get the wool buffing pads for this ?
I just pick up dewalt kit i did my 2009 gmc 1500 crew cab pickup took both 5 amps battery’s and left with battery with 3D speed polish it’s came out great this machine is no joke very powerful and smooth
Thanks for the review 👍👌
My pleasure 😊. Thanks for watching and commenting.
What’s the power like when the speed is low to mid range on the dial?
I gotta have one! But my DA corded polisher uses 6" pads. Wonder if I can change the DeWalt's polishing head over to a 6".
Hey there and thanks for the review.
Is it better than Ryobi dual action cordless polisher?
I am not a professional by any means but amatuer doing my cars and friends cars and I want to sell my cheap AutoBrite DA12 polisher for this DeWalt cordless.
Is it heavy to do vertical panels? Will it work for paint correction? Is it ergonomic or tires your hand in 10 minutes?
Thanks!
Can't find that D-ring handle
Where did you get it sir ?
What’s the biggest polishing blade that can be used on this device
I have the DCM 848 20v and i agree with the review From living with the unit doing semi pro work, ie part time hustle, it does requires some break in but after that dialing in the speeds works better. Dewalt triggers/dials are all kinda like that though. Its is also variable speed with a lock feature very handy. The backing pad is not a standard pad and can not be changed out with another company, a beef i have with the unit but not much of one seeing how strong it is. I"ve done a Single stage paint correction using One 6 AH battery on a 2019 mustang with 2 bars left. No reason to be going ludicrous speed all the time. I do have a pair one charging and one in use. AH and two 2 AH that were with my cordless tool kit that i rotate in and out to keep the 6ah charged up it also makes the unit easier to handle in tighter spots and lighter. As for vibrations and noise its not really bad at all i've used it for hours and i don't have that numb arm feeling in my arms after a long session. If you have 5 inch hook loop sanding pads it should work as a sander never tried it though.
Thanks so much for sharing your experience with this polisher. It's really not a bad polisher at all, and it will definitely get the work done. Compared to a FLEX, the DeWalt needs some refinement, but that's also reflective in the price. Glad it's working for you. Thanks again for watching and commenting.
So dobyou mean you have to buy dewalt brand pads only to work with this machine?
@@fallguy6558 any Velcro backed pad of the 5.5 - 6 inch variety will work you just cant change the backing plate to a larger or smaller size.
How long are you supposed to charge an empty battery? Mine went out when i was polishing front fender and hood on a Lexus SUV, and you said you can get through a whole car with the 2nd battery still had juice left. Thanks for your time
@@Plin321 till the charger light is solid. It depends on the compound of the polish as well. i use griots fast correcting cream. I was also polishing a mustang not and suv. Some require a lot of pressure. which will wear the battery out faster. If you having cutting issues try a more aggressive pad or different polish. I have a spare set charging and now have 2 6 ah and 1 9ah waitley battery with the two ah charging for a pinch. I ha ve a charger station.
So what battery pack should I get to use this machine 2ah,4ah, or 5 , 6 ah??
What rpms you were using ?
Is the Model DCM848B from Lowes the same?
Orbit Size Of this machine? My mt300 has 8mm orbit Size and free spinning.
You're right on at 3:35, didn't really see/feel speed change from 4500 to 5500; defective?
is this a short throw or long throw?
@4.08 when he says trigger is Very Sensitive - What Size pad is that ???
Good Review Video BTW
Is the 848B or 848P2
Trying to minimize (or future-proof) the tools that I purchase. Can I use this use as a sanding machine with the proper disc?
You should be able to do that. Porter Cable was probably the first orbital polisher to hit the market decades ago, and it was first a sander. This DeWalt should do the same with no problem.
Yes. Just get hook and loop pads
Hows it compare to a rupees
is a 7 inch pad or 6.5 to large for this polisher?
Typically, random orbital polishers use 5" or 6" pads. I'm sure you could run a 6.5" pad on here as well. Thanks for watching.
I own this polisher and enjoy it. I noticed that you guys didn't talk about its trigger lock and that also everyone that was using the trigger lock either. With a cordless polisher, one of the biggest things to me after getting the trigger locked is to find a way that to hold the polisher in a more comfortable position.
I've AIO polish on a sedan with one battery just barely. It depends on what battery you use. M18 5.0 can take more amp load those can last while awhile.
Sorry about that. You are right, and we've covered this in other reviews. Once the trigger is locked, you can grab the back of the tool, near the battery and guide it where you want it. Wow, if you can polish the whole car with just one battery, that's really good. Thanks for watching.
Dumb question, is this a rotary or a da polisher? I cant find anything
@@djstock3 if you actually watched the video you'd know it's a DA. Look up video on the difference on polishers.
@@Shoptoolreviews whats the difference between the DCM848 and the DCM849? They look doing the same
Thank you for the great video. Between this Dewalt polisher and the Griot's Garage G9, which one will you recommend for a non-pro person simply based on their performance? Thank you.
Definitely, the G9 is a better polisher and cheaper. If you need a battery powered model, then get the DeWalt. Thanks for watching.
@@Shoptoolreviews Thank you for your reply! Have a great day.
Do they make a dual action polisher? This will be my first tine using abrasive compounds and I’m nervous using the rotary because of the heat etc..
@@6atlantis Hi. Did you mean Dewalt? I believe what this video is talking about (DeWalt DCM848 20V Random Orbital Polisher) is a DA polisher. I am not a professional, so please use my words as a reference only. 😊
@@RocketCouple I just rewatched it, I thought it was an orbital not a d.a. Thank you
Thanks for the video Tim. I think I'll go with kobalt
Excellent choice. Thanks for watching.
Does it have a wired adapter ? If you get stuck half way through a jo b maybe it would be a way out ? What’s your take on that ?
No, this is Not a FlexVolt tool, so there is not wired adapter. You have to use a battery. Thanks for watching and commenting.
@@Shoptoolreviews wait so flexvolt tools have a wired adapter? That’s news to me. I know of just the saw has a wired adapter because it’s so heavy duty. But you’re saying evens the grinder And circular saws have a single corded adapter?
Just change the battery
It's also a great massage tool for your thighs, back, calves, and shoulders.
Now that's something that we haven't thought about, but we'll have to try it out. Thanks for watching.
Will it work on a frenulum?
Nice review, I wonder how this compares to the new Ryobi DA polisher. And I hope people listen to this video about multiple batteries. I just read a review of it on Home Depot and the guy claims he did his whole car on 1 battery and still had 3 battery bars. And he claims he probably could have done his other car and his truck - all on 1 battery lol. He has to be talking about waxing but some people will read a review like that and think they can paint correct all day on a single battery I'm sure.
Can I use a 3" or 2' backing plate?
No, I don't believe that a 2" and 3" backing plate will work with this. The machine is too big. Thanks for watching.
Backing plate mounts differently than the typical plates
But even if it did bolt up, plate will be too light even with the heaviest pad available.
This issue will induce machine imbalance and vibrate you and it's internals badly.
Can I use it as a sander if I use sand paper disk?
Yes, you could use it as a sander. Thanks for watching.
How powerful is this unit and, how does it compare to a rupes? Does it stall on curves?
For a cordless unit, it's pretty powerful. It's pretty tough to stall when you have it full throttle. It just doesn't have an 'in-between' speed. I wouldn't say that it's more powerful than the Rupes MkIII. Thanks for watching.
Thanks for the reply! I need my machine to be wide open , I do a lot of Correction work. This might work for me.
Do you need specific dewalt pads? Or can you just buy random ones? Thanks!
You can run just about any hook & loop pad. We were running a Sonax pad during this review. Thanks for watching.
@@Shoptoolreviews in this video he is saying the Dewalt plate is proprietary. Youre saying its not th-cam.com/video/JblCKP0SUhs/w-d-xo.html
Hello sir how r u from India. Nice to see you
What's your favorite 20v cordless polisher. Thanks.
FLEX has the best cordless polishers, by far, but they are expensive. They're 18V, but that's the same as 20V Max. Thanks for watching.
Fyi, for the main 3 cordless (dewalt,makita, Milwaukee) you can simply buy adapters to run one battery system
That's not a bad idea for occasional use, but we definitely don't recommend this for regular use. All these companies use two-way communication between the tools and the battery for continual diagnostic information during use. If they don't have their own battery, the tool does not know this critical information. Plus, this will definitely violate the warranty with any of these tool companies. Thanks again for watching and commenting.
@@Shoptoolreviews I've been using them for years this way day in day out, no issues
I don't doubt that one bit, and I'm glad it's worked for you. As soon as I recommend this, someone will have a failure and blame me for them not getting the tool warrantied.
@@Shoptoolreviews I hear ya
In in the detail business and besides the nxt ridgid vac..everything else I use..polishers , air compressor etc only has like a one year warranty anyways
Adapters need certain communications also or they won't work..I had a flex to m18 adapter..would work on lol thing , but would work on the polisher
Thanks for that info! I had no idea
Is this high vibration?
The DeWalt does have some vibration, but it's not bad.
I want to try Ryobi’s new d.a
Love it. But the vibration is stronger than my other Old cord unit. But I don’t do this often. So it is fine
I feel like the sound almost makes it seem like there is more vibration than there actually is. You are correct, there is a some vibration, but it's not too bad. Thanks for watching and commenting.
Just need to use a different weighted pad to make it smoother, not a big deal
Bizno Booyo not a pas issue, it is true, not big deal for weekender.
@@ometofu no, what I'm saying is you can tune out machine vibration with different pad weights....this holds true with every machine
Different weight Backingplates work too, IE 5in swap on a 21mm... this situation you still need a heavier pad
Like my Makita po5000C loves a 15 gram pad and is smooth up to a 25gram pad..anything more it'll vibrate
All the old school 8mm machines are smoothest with a LC Thinpro
Reason Rupes has a system..
I do a free air spin with pads to find which makes my machines the smoothest, as I'm sensitive to hand numbness
Bizno Booyo ah ok. i will try
has anyone had to replace the backing plate on their dewalt polisher yet? I got mine and I searched everywhere online and there is zero mention of a replacement backing plate. My concern is because the backing plate is a hard foam binded on plastic which makes me feel down the road it'll break as it has happened to me with my torq foam disc from chemical guys. Any tips on where to replace or get a replacement would be appreciated! Or if there is a way to convert the machine to use a standard disc pad would be great too!
Have you figured this out yet before i buy one of these? lol
Nevermind another comment says it cant be changed.
@@PumaM90 yea actually I figured it out after taking off the 4 torx screws and noticed there was printing on it. Also there was a service manual that confirm there was a part number
www.toolservicenet.com/dewalt/en//Dewalt/METAL-WORKING/SANDER-POLISHERS//p/DCM848B
You have to order the part from a dewalt service center. The part number is N649086 and the replacement part isn't too expensive either
Need to show it being used and results
What’s the minimum speed please?
You can go as slows as you want. It has a variable speed trigger. Thanks for watching.
@@Shoptoolreviews i only have a 1.2 battery how long would it last? At least 20 mins?
It's great to polish bronze/brass objects such as ornaments bells etc lol
That's a pretty cool use. Thanks for watching.
Is it as good as the makita one
Better than the cordless makita.
@@Shoptoolreviews hi i meant the milwakue battery pollisher
Is it forced rotation
No, this is just a Random Orbital, which means it's not forced rotation. Thanks for watching.
Dual action..makita and flex has a cordless forced...I'd recommend the makita
@Therealdeal84 side by side testing yes, it's smoother and cuts faster..only one that can swap on a 3in plate if need be
It has the most RPM coupled with the second most OPM
More ergonomic in my opinion...but that one is all dependant on the person
@@PghMtbRides you like the makita that’s interesting they make great stuff I’m looking for one
@@PeteyMcSavage yes, and I still don't trust the new flex XCE with the crappy 3 studd backing plates...version 1 and 2 liked to sheer off
Version 3 are the red plates..jury still out on those
RUPES Mille is a light weight..boats will kill it.
Original flex 3401 isn't smooth and also gets hot
How does compare with the Milwaukee
Milwaukee does not have an orbital polisher. We wish they did. Thanks for watching.
@@Shoptoolreviews they announced one now as soon as I bought a g9 from griots
Worries about product getting airborne and clogging motor: doesn't wear breathing ppe 🤣 jp, thanks for the video
way to make me buy another grinder on top of my angle grinder....
Da is opm. Not rpm
You are correct, sometimes my mouth gets ahead of my brain. Who am I kidding, it's just my brain that's the problem. :) Thanks for watching.
Bowel movement
Makita
OPM not RPM this is why I despise all this channels, they spit out all this BS without knowing a damn thing. It's not a grinder! DO YOU EVEN KNOW WHAT 5500 ACTUAL RPM WILL DO TO A CAR?!
This tool is absolutely junk. I have 2 5ah powerstack batteries a 15ah battery and went through all 3 buffing a 2023 Nissan frontier. Here's what happens and DeWalt engineering department can't figure it out. Start with fully charged batteries 15mins and drops from 3bars to 2bars when it does it cuts speed in half so have to put on full speed to compensate. This tool is absolutely freaking junk literally have to have 4 or 5 batteries available to do a small car or truck. I think DeWalt should recall all of them
The car is again going to get dirty anyway.
Durata batteria?
