DeWALT 20V MAX XR Brushless Impact Driver Kit

I generally buy Milwaukee or Dewalt system tools because they are available locally and they both have systems that are uniformly excellent and well supported. Along with my miter saw, I use my drill driver and my impact driver most out of all my cordless tools. I recently started upgrading my cordless tools from 18v to 20v and went with Dewalt because most of my old tools were Dewalt. My old tools still get work done and I could use 20v adapters on my old Dewalt 18v tools to extend the time to replace those, so I stayed with Dewalt. The first purchase was the 791 drill driver, which I immediately loved for it's ergonomics, small form factor, light weight and long run time on a 2Ah battery. After that experience, the impact driver was the next logical thing to replace. I had an upcoming deck replacement, so I bought this little 787 with the 4Ah batteries. There's really no fun way, outside of fire, to remove old deck boards that had been screwed down decades ago. You can muscle them off, cut them off, disassemble them or a combination of all three. I elected to disassemble them, to later avoid hitting cut screw shanks or tearout voids with the new Trex connectors that were going in. This little guy had to work hard to unwind close to 1500 rusty screws on a 600 square foot deck. The result? Awesome. This thing unzipped screws all day before needing a charge. Some of those screws it had to hammer at for 10-15 seconds to get them to break loose, so this was no cake walk. The LED light was awesome for finding sunken screw heads as daylight waned and the belt hook was great for hanging the impact on my belt as I moved around. When reconstructing portions of the framing of this deck, I had to run a series of lags and even at the end of the day, this thing zipped them in like it would break them off before it ran out of torque. One thing to note is the move to brushless motors. Brushless motors are noticeably more efficient and if you are on the fence about replacing perfectly good older tools, this feature alone may make it worth the switch. I really notice the effect of the brushless motors most on the bigger tools, like the reciprocating and circular saws. My older tools run down even the bigger 20v batteries much faster than the new brushless version of the tools. To sum it up, this is a very impressive little impact driver in a kit that gets you two 4Ah batteries to boot. It's a solid buy. I love it. The Milwaukee M18 Fuel driver looks to be every bit as good, so I think it boils down to if you're already red, go red, and if you're already yellow, go yellow. The 787 won't disappoint.
