Great tool! Very Comfortable
I use it for steel & wood framing, the battery kept up all day long. Very light, I've used Dewalt & Milwaukee for 15 yrs. + of doing carpentry etc. But I'm constantly learning and our tools just make our job that much easier. And Milwaukee is the at the VERY TOP OF THE TIER!! Great tools, will never use a DEWALT again!!

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
