Asked by Dellburt May 12, 20212
AnswersI have two of these drills (bought about 5 months apart) and they both make this noise, mostly when stopping from a higher speed. I thought I remembered that the drill had a brake so I looked it up in my manual. Under "Variable Speed Trigger Switch" it says "To turn the tool off, release the trigger switch. Your tool is equipped with a brake. The chuck will stop as soon as the trigger switch is fully released." The clacking noise, when releasing the trigger, is kind of odd but it does appear to be the brake. I like my drills but I don't use them enough to be able to determine if the brake clacking causes unusual wear on the them or not.

Asked by NW April 18, 20215
AnswersNo The female 18v slot in the radio battery compartment is incompatible with the male tip of the adapter This appears to prevent the radio nicad charger from charging a lithium ion battery which could possibly cause a hazard Same goes for the compartment in the 18v vacuum I have all of the above

Excellent quality and portable too. Used this circular saw actually at home depot for wood that didn't fit in my suv. Just measure what you will need before shopping then use it in the parking lot. Strong and battery life is excellent.

How can I give an honest review about using a product when the product comes with not only 1, but 2 DCB207 batteries, WHICH AREN'T COMPATIBLE via the manuals provided. The batteries should have been DCB203's since they would be the closes looking to what was shown on the picture!

This combo was a great deal with the 5ah battery. This is my first XR drill and you can feel the power difference compared to the regular Dewalt Max drills. I think three settings for the led light is kind of a funny feature, but hey maybe one day I’ll need to adjust it! The bag now has a sweet rubber “Made in the USA” logo which is cool.

Perfect size
I got this saw as a supplement to my corded saw and it has quickly become my go to. Originally I got this saw to cut transitions and trim the plywood edges of half pipes. Quickly however it has made its way into primary rotation in my tool kit.

Customer review from dewalt.comOct 5, 2020
Good strong drill
Mostly happy with this drill. Has plenty of power. Speed is good. Nice weight and size. Comfortable to use. Down side is I didn't know it doesn't have a bit holder. This is an optional accessory.
Not so sure it's made in usa. Bag has a big patch on outside that says made in usa then inside says made in asia.

I am very happy with the tool itself, but Home Depot shouldn’t deliver power tools in the DeWalt box, the likelihood of it getting stolen was astronomical, with that said, I shop Home Depot regularly, and will continue, but when customers order expensive things, you should put them in a generic box, that won’t make it as much of a target please

2 out of 2 broken in 18 months.
Power was never a problem, but they break easily and DeWALT doesn’t stand behind their tools with their warranty. Go Milwaukee or Makita if possible, but I’d even take a rigid over this.
