Handy cordless polisher for various surfaces
Almost perfect for quick jobs, this lightweight tool offers good power and a comfortable grip. Its 7-inch pad helps cover surfaces efficiently, making it a nice option for both professionals and casual users. I’ve appreciated the longer battery life, especially when working on larger areas. Overall, it’s a reliable, easy-to-handle device that has made my polishing tasks much smoother.

More powerful than expected.
This polisher has been a lifesaver for polishing the aluminum fuel tanks on my Freightliner Cascadia to a mirror shine. This cordless polisher is much lighter and more versatile than my corded polisher. It has as much power as my corded polisher. I can get almost an hour of constant runtime with three batteries. It is balanced well and has a smooth operation that is user-friendly.

Powerful Cordless Polisher for Professional Results
This cordless polisher is an absolute game-changer when it comes to getting that perfect shine on your car or any surface that needs a good buffing. Let me tell you, this tool is a beast! The DEWALT 20V MAX* XR Cordless Polisher delivers some serious power without being tethered to a cord. The variable speed settings give you the flexibility to tackle different projects with ease, and the 7-inch size covers a good amount of surface area with each pass. One tiny downside is that since it's a tool-only option, you'll need to invest in batteries and a charger if you don't already have them. But trust me, once you experience the freedom of cordless polishing with this bad boy, you won't look back. It's like having a professional detailing service right at your fingertips. Smooth, efficient, and reliable - this polisher is a must-have for anyone serious about getting top-notch results.

Mastic Removal Tool
I use this with a diamabrush mastic removal tool for the edges. It runs slowly enough not to sling water all over the place. Got the job done. Manufacturer may frown on using it for this.☹️

Works great. Have back up batteries ready to go.
I love this buffer. The only problem is a fully charged battery only lasts about 10 min so have back up batteries ready to go . Much better to work with at this at our professional body shop.

Worth it!!
Happy to have this! It gets a little heavy when used for a long time especially with a battery. Otherwise, it works wonders. Worth the money!

Excelente.
A politriz é fácil de usar e funciona muito bem. É potente, e talvez exija uma bateria de maior capacidade. Mas é uma Dewalt. Muito boa.

Perfect for buffing boats with power and mobility
I bought this DEWALT cordless polisher to buff and restore the gelcoat on our boat and it’s been incredible. The cordless design makes a big difference when working around the hull, especially in areas where there’s no easy access to power.It has more than enough power to cut through oxidation, and the variable speed gives great control whether you’re compounding or doing a final polish. The 7-inch pad covers a lot of surface quickly, which is a huge plus when working on a boat.With a 5Ah battery I can usually get through an average-size boat without needing to recharge. It’s comfortable to hold, well-balanced, and doesn’t wear you out after long sessions.If you maintain your own boat or do marine detailing, this is an excellent tool. No cords, no hassle, just professional results wherever you need them.

No Battery!
I just received the item, and there is no indication in bold or in the item listing that it comes without a battery. Upon further inspection, I noticed a small note in the description below the photo, title, and subtitle stating "W/O Battery," which I find misleading.
