I've had this impact driver for a while usually used it for smaller task door, cabinets, light fixtures and such. My 20v impact driver got misplaced so just used what I had and this 12v impact driver went much farther than I would of ever imagined framed and decked porches never slacked up I wanted to see just how far it would go and after about 6 months it was a 4 inch screw securing a set of treated steps to the porch that literally made the drill go up in smoke in my hand this is one amazing tool

I love my 20v Max tools and when I need to work all day, I reach for them. But for everyday projects and repairs, this 12v Max impact driver is my go to tool. It is lightweight enough that I can use it over my head with no problem. The quick change bit makes it easy to swap between different types of bits as needed. I am loving it so much, that I am considering buying a 12v Max drill as well for those times when I need a tool with a chuck.

About the DeWalt 12-volt Impact Driver.

I found (and then bought this tool [a Kit: DeWalt 12-volt Impact Driver / Drill / 2-batts / charger / bag] on a discount table about 4-5 yrs ago at HomeDepot.

I almost DIDN'T buy it.

The reason being, I hadn't used or ever seen - or at least noticed Impact Drivers being used by others in my trade; or for that matter the other trades (I'm an electrician). I knew that auto mechanics used pneumatic impact drivers/drills - that's it].

I was really ignorant as to what an Impact Driver was capable of doing. But because the price was too good to pass up, I 'took the chance' and bought it anyway.

After I purchased it, I don't think I even tried using it for a while; not being familiar with it.

But once I gave it a go...Wow! Was I glad I did! And very glad I decided to buy it!

Skipping everything else I could say about this little 12-volt champion; I'll just say that I rarely, rarely use my drills now...only when I really need to use one. Usually when I want to or need to use my older NON-quick change drill or Uni-bits. Otherwise, it is Impact Driver all the way.

Recently I bought the 20-volt DeWalt Impact Driver & Drill Kit (discounted again from HomeDepot). The 20-volt naturally has more power than my 12-volt, and I do use it. But for my particular needs, I find myself mainly using the 12-volt DeWalt Impact Driver to accomplish most of drilling and driving needs.

Why? It is lighter in weight and more compact than all my other drivers and drills; and yet has more than enough power and endurance to handle the bulk of my needs for any given project during any given day.

I really don't use the supplied handle, but bought the 'loop' holder that clips to my tool belt, and I'm off to the races.

Lastly, besides the DeWalt 12-volt & 20-volt Impact Driver / Drill Kits; I have the Rigid 18-volt Impact Driver / Drill Kit; and the Milwaukee 18-volt Rigid Impact Driver / Drill Kit; as well as a 12-volt Rockwell Impact Driver.

Out of and above them all, I find myself using and preferring to use this 12-volt compacted power house: the 12-volt DeWalt Impact Driver. The 20-volt DeWalt is next in line; the Milwaukee and Rigid about even; and I never use the Rockwell anymore (lacks power; speed and will not hook to the belt looped hook).

In addition. I rarely use any of the drills that came in the kits. The drills I use the most up to this point have been the 12-volt & 18-volt Milwaukee Hammer Drills for drilling into concrete.

Well done DeWalt.

Yes. Sometimes my quick-lease bits are ejected from and go falling to the floor from my ladder. Meaning, at times, when I have NOT BEEN CAREFUL, and I place the nose of my Impact Driver into those holes supplied in the top of my ladder. The quick-release mechanism can get caught and it CAN eject the bit onto the floor.

Yes. It is annoying when it occurs. Its rather rare, though, I get it caught that way. I've learned to be careful not to just JAM the Driver INTO the ladder hole (or with some quick release mechanisms, if you YANK IT OUT of the ladder hole without being careful). But for me, even not being that careful, rarely does it get caught in such a way that it expels the bit.

Another worse scenario: Being in a HOT ATTIC for example. While drilling, say, a hole down into the top plate of a wall with my Impact Driver. If while PULLING the Impact Driver's nose UP out of the hole; I fail to be conscious NOT to allow the Drivers Quick Release mechanism to get hung up on the side of the newly drilled hole I made. I may end up seeing (or hearing) my favorite bit goes plummeting down into the wall (perhaps, never to be seen again).

Yes. That is more than annoying! It has happened to me. Yet for me, many of the times this has occurred to me I have been able to retrieve a 'lost' bit with a powerful magnet on a string or rod (but not always). It is rather rare though, that this has happened to me over the years.

And frankly, it has occurred more often with a DRILL, where the bit has come loose during drilling. It might not be loose enough not to continue drilling; but loose enough, that after cutting all the wood away (that was keeping the bit from falling) - there goes the bit!

All in all though. I trust a quick release mechanism, more than a drill chuck to keep me from loosing a bit. I'm just very careful if and when I may need to stick the quick release mechanism of the nose of my Impact Driver into the hole in the wood, drywall, metal or otherwise...PLUS, I carry an extra bit with me just in case. I often say to others or a helper, "Take an extra one of those [whatever bit or part]: One to drop or loose; one to use." Murphy's Law is ever present. But sometimes you can out wit it...sometimes.

This tool has so much power that it will drive a four inch deck screw with little effort.
And that means it will do the job many times before the battery has to be changed out.

I had this tool for about a year and hate it. The bits fall out. I lost two yesterday when they fell into deep insulation while working in my attic. I also spent an inordinate amount of time chasing them down into the gutters while working on my roof last year. Just buy two drills and a bit holder.
