One of the best reviews i have seen of this machine. Not sure why it's not getting more attention. It has its downsides in terms of weight and noise but it's a beast of a cordless DA. In comparison, i found the Flex cordless to be much less powerful and found it stalled out a lot more. In terms of batteries, i can get through each stage on a Mazda CX5 with 2 5ah and the Dewalt fast charger which can charge a 5 ah battery from flat in 30 -35 mins. Otherwise, rotating three 5ah batteries on the standard charger should be enough. Highly recommend this cordless DA.
Thanks man, I appreciate your support! I really like my DeWalt. It’s super handy for spot correction and in a pinch, I can pull out my other batteries and do a whole car. Thanks again for watching!
What about vibration?
I could handle noise but not vibration
@@Carlos.Rivera I dont find the vibration excessive but if you are coming from a corded Rupes you may think differently. It's powerful so does have vibration but from all the reviews i have saw no one really mentions vibration as a negative.
@@Carlos.Rivera not to bad. Not as smooth as a flex, but cheaper. If vibration is an issue for you, this may only work for small areas for you.
Brazil loves Dewalt, congratulations on the video, success
This is a very useful video, thanks. I’m a detailing enthusiast, not professional. I currently use a RUPES polisher but this Dewalt looks a good addition to my kit box. I like the lack of a cord 👍
Thank you! Yeas it comes in handy often. It’s also featured in my newest video. Cheers
Excellent video!
Thank you for your efforts…
🙏
Thank you!
👍 Thanks for posting this video. I have been looking at this polisher for a while now and I was on the fence on purchasing it. Looks like it works really well. I have always been impressed with DeWalt power tools. They make some of the best although my current polisher is a Makita PO6000C Forced Rotation Polisher. The reason I love the Makita (although the throw is only 5mm) is the fact you can switch from FORCED back to DA on the fly through a small switch on the side of the unit. I cut the paint using forced rotation and then flip the switch and finish down using the DA mode. Works fantastic and it's a super smooth machine compared to my Flex 3401. The 3401 is a stronger unit, BUT, it goes all over the place due to the counter clockwise rotation and takes a more work to keep it steady. Not the Makita. That thing is smooth like a Ferarri of polishers. It's the only forced rotation polisher that has the ability to flip back and forth between DA polisher and Forced rotation polisher at the flip of a switch. There is no other polisher in the world that does that to my knowledge. So, although it's pricey, it's worth it. Makita just released a new version of it as a CORDLESS/BATTERY powered unit. Again, it's really pricey which is why I haven't upgraded yet. I was thinking about this DeWalt unit which is about $200 cheaper than the Makita Cordless and has a much better orbit and throw. I am seriously considering this DeWalt as I have heard it's a great cordless polisher, even rivaling the Flex cordless machines. I'll be giving up the forced rotation ability of the Makita but for 70% of the polishing I do, I don't need it anyway. I definitely am upgrading to a cordless unit. After using my new Flex PXE-80 mini cordless polisher for the past couple months, you never want to go back to using a cord after that.
why not just buy the new Makita kind of a no brainer with your above post actually why do you even need another one except for the cordless issue in which case if i was so happy with my current and then the company came out cordless i would just buy that
Totally agree about using cordless, although when I’m doing an entire car, I prefer corded. Ultimately I chose the dewalt because they are a solid Brian’s, and I have a bunch of other dewalt cordless tools, and have been using dewalt for years.
@@YingYangStang The main reason for not buying a cordless Makita is it only has a 5mm throw and I want something with more throw that that. 12 to 15mm is what I want and the DeWalt has that in that cordless. That Makita is an excellent machine though. And the ability to switch between forced rotation and DA polishing is a great feautre. I think Makita more designed the machine as a wet sanding machine, hence the reason for the 5mm throw.
@5 Star Detailing LLC Let me know how the DeWalt cordless works. I am seriously considering the DeWalt as it has a 15mm throw which seems to be a good middle ground with the long throw polishers. I saw a couple reviews of it and all are positive. The only long throw I have ever used in the Dynabrade long throw attachment to a rotary which I have. I am pretty sure that most companies who make long throw polishers got their inspiration from the Dynabrade long throw attachment to a rotary. It was around a lot longer than the long throw polishers and I think it is actually longer than a 21mm throw slightly. Not sure the throw exactly but it's quite a large throw. It is very difficult to get used to and it takes a while to master it but that bad boy will DO some paint correction!
Good!!
Try the bigger batteries, I had this polisher a yr 1/2 ago and got the kit with the dual 5ah batteries but tried the 6ah it lasted about 15minutes more but when I tried the 9ah flexvolt and the 12ah flexvolt it lasts 3 times the amount of time the 5ah battery last and only used 2 batteries for a full size car like a mid 90's Cadillac and 2000's Tahoe/suburban use those smaller batteries for a drill and get a larger battery for polishing and paint correcting!
Good to know, thanks for the tip!
Then again that 9ah and 12ah battery cost just as much as the cordless polisher
@@jesusbernabe5983 It I ly makes sense to invest in the polisher If you're already Invested in DeWalt, that polisher was the first polisher that started my detailing career almost 30 yrs ago and when I noticed they've made a cordless orbital I was all over it. I purchased the whole kit for $450 and just trying it out I knew first hand that the smaller batteries wasn't going to cut it. Tried the bigger ones and it made perfect sense plus they ran 3 times longer, I've seen a DeWalt ad talking about using the 60V flex volt on 20V tools and that the battery only uses 20v verses what the took needs to operate. Once they showed me the drills were stronger and the battery lasted longer I've ordered a few, most times ppl are running sakes on DeWalt batteries because they're so expensive they are more commonly on sale than not you just have to catch them. But furthermore I've sold that polisher and all the batteries I've had buy thinking on purchasing another one and DeWalt is releasing a bigger stronger battery by the beginning of the year
@@jesusbernabe5983 true true, if you plan on using it often, it might be worth the price.
@@TurnerMobileDetailing well I also have a mobile detailing business and a arsenal of dewalt power tools… so it’s a perfect investment for me
Ive been doing this long enough to feel that this Dewalt as well as Flex cordless DA polishers are the best options out there. I too use Hexlogic pads. For foam pads they are my #1 preference and shine mate diamond pads i like too. They last longer than any other brands. Buff&Shine for my microfiber pads
I have a few questions about the Subaru vehicle at the end.
1. What grit sandpaper did you use to sand the vehicle?
2. What is the brand and part number of the first step you used to polish?
3. What is the brand and part number you used in the second step of polishing?
This is a great video on the DeWalt polisher. I am thinking about purchasing this unit.
Hello, and thanks so much for watching! I never actually wet sanded the Subaru. I did do some wet sanding on the truck you see in the first part of the video. If you watch the video that this video is taken from you can see that process. If I was to wet sand the Subaru I would have used between 2000 and 3000 grit wet sanding discs. You can buy hook and loop foam cushions for the sanding discs that mount to your DA. If you do wet sand, be extremely careful because you can burn through your clear coat very easily, especially on body ridges. I would suggest practicing on an old body panel you can get from a junk yard first.
While polishing the Subaru, I first used Meguiars M105 Ultra Cutting compound with a yellow Hex-Logic pad, and I finished with Meguiars M205 finishing compound on an orange Hex-Logic medium pad. I hope this helps, let me know if you have any further questions.
bonnet are already shiny ????
what pads did you use with this machine
Here I’m just using an orange hexlogic pad from chemical guys
What is the advantage of using a polisher over hand waxing?
Speed. You can apply the wax over large areas faster. But in tight areas you’ll still need to apply by hand.
Any chance you have experience with a PC7424xp? Finally going to upgrade it but really wanting to go cordless. I have dewalt, Milwaukee and ryobi batteries. Since Milwaukee doesn't make a DA looking into this onw or the ryobi. The PC7424xp is just not cutting it. It's so slow. Would this be better?
I used to use a porter cable years ago, I don’t remember the model, but it was old, like before the market was flooded with professional level DA’s, but I haven’t used this particular model. But looking over the specs, it looks like a decent little machine, and compared to the dewalt DCM849B, it’s similar. Unit looks like the PC have a higher OPM, however, with a DA you really never go beyond 5000 OPM in use so that’s kind of a moot point. Remember that DAs are slow in nature, they can get bogged down on non-flat areas and stall. A rotary buffer is much faster at paint correction, but much easier to damage the surface, so just be mindful of that. That being said, the dewalt is a great machine as long as you don’t expect out of it more that it can do, or any DA for that matter. Makita also makes a good cordless DA. Hope this helps.
Is this machine 8 mm throw or 15 mm? I hear mixed things online & all dewalt's website says it "2.1 inch" which translates to like 53 or so mm. Even cut in half that comes out to over 25 mm.
I believe it’s only 8mm throw, it’s minimal, may even be 5mm. Honestly it been a while since I’ve researched those numbers, but it’s not higher than 8mm, that I know.
It’s about 13.5 mm
When using the battery charger, does it work with 220v(asian country) outlet? or is it strictly for 110v outlets?
It probably wouldn’t hurt, but it also most likely wouldn’t charge enough/properly. I wouldn’t bother if I were you. But I’m not an electrician so so don’t take my word as gospel, be careful.
110 volt ! You might want to check into an adapter for the 220 voltage to charge this battery
Is this a forced Rotation DA?
No.
@@TurnerMobileDetailing Can you give me some names and models of some buffers at are?
@@ajlove6969 I would recommend the Rupes or Flex forced rotation. Makita makes one too. I’m not sure the model names, but just google them and you’ll find them. I believe the flex has a battery powered forced rotation as well.
@@ajlove6969Flex 3401
What speed is this being done at?
The video is in real-time, I didn’t speed it up or slow it down at all. I typically polish at about 1 inch per second.
@@TurnerMobileDetailing the tool, not the video 🤦♂️
@@mattramos6001 about 1” per second
@@mattramos6001 It can also depends on the condition of the paint. If the paint is in bad condition then I’ll move a little slower, but if the paint is an already good condition I can move a little faster.
@@TurnerMobileDetailing thank you. I guess I need to be more clear in my question… I am asking about the motor speed of the tool that you are choosing (it’s adjustable), not how fast you are moving. I just ordered this tool and I’m curious a good speed so that I don’t use it to slow or too fast and cause any damage to my paint. Thanks again.
Tool looks HEAVY - as far as weight goes how does it stack up against the FLEX XFE 15 ...? Also I heard the FLEX runs out of power like half way through as in power push drops off doesn't die just diminishes to half or less power - that was from another reviewer - I don't have a lot of money to make a mistake here and I'm trying to make a decision between a Makita, Dewalt and Flex or anything else you want to suggest. I am an amateur and want to start a business hopefully - this guy says the FLEX falls off - care to comment czcams.com/video/JblCKP0SUhs/video.html
I’m happy with my dewalt. If your looking to start a business and on a tight budget, but insist on a battery powered polisher, I suggest the SPTA version. It’s good enough to get started. But again, I wouldn’t buy a battery polisher and expect to be doing whole cars, and 2 step corrections with it, I’d use a corded polisher for that. I love my maxshine polishers for corded machines. Just remember that unless you own a bunch of batteries, battery polishers have their limitations and their place. As for the dewalt performance, I’ve never had problems with it dying off after a short time. I don’t use it for full vehicle correction though. However, when I have pushed it’s limits, like when I did the hood of my truck, and the forester in this video, I was happy with the amount of time I got out of each battery. I did the whole hood on my truck and still had juice to spare on one battery. Also, it runs smooth enough.
