Reddit reviews DEWALT 20V MAX XR Impact Driver, Brushless, 3-Speed, 1/4-Inch, Tool Only (DCF887B)

I would say the bigger the more dangerous. Most often the threads will not break and you'll be left with a bolt/nut digging into whatever it is that you're anchoring. I have two DeWalt impact drivers: both cordless 20volt, one with approximately 160 Nm and a 1/4" chuck, the other is a 1/2" drive high torque driver with a maximum output of approximately 950 Nm. I've snapped grade 8 half inch lag bolts with the big one.

All in all I would suggest for standard use a 1/4 inch chuck, not drive, light duty impact wrench. Anything you feel might not be tight enough go ahead and use a socket and ratchet wrench to confirm and you should be all good.

Dewalt 20V Impact Driver

I would get this:

I have that set and I use the impact driver 90% of the time. It is lighter, smaller (easier to fit in tight places) and more powerful. I pretty much only use the "regular" driver from the set when I have a special bit that won't work with the impact driver.

Edit: I actually just realized I have this brushless impact driver:

https://smile.amazon.com/DEWALT-DCF887B-Li-Ion-Brushless-3-Speed/dp/B0183RLW8A/

but the "regular" driver from that set. Brushless generally gets a bit more life out of a battery, not a ton of other difference.

Also, you can do most exterior work (drill into brick, concrete, etc) with the impact driver and the correct bit(s) (or the other driver and correct bits). I've put in concrete anchors in slab, drilled holes to mount things in a brick wall, etc with pretty much the first set I linked.

Getting the numbers off Amazon spec sheets. I see the weight on the 18V Impact Driver, but not the new one. Having lifted one in the store it appears to be similar in weight.

Note this is for just the tool. As I said, the Lithium battery appears to be 1# lighter, but I could just buy new batteries for far cheaper.

I see your point about the better power, but I've yet to encounter anything that it struggled with, and I've done just about everything but metal working or car repair.

You're also mistaken about the lights. Not sure if it's LED or not, but there's at least one bulb.

Brushless vs Brushed is nice, but I don't think it gets me much. First, it makes the tool more efficient, but I can just switch batteries. Second, it increases the lifespan of the tool, but I don't care if I'm replacing it before it wears out.
