Reddit reviews DEWALT DCF899B 20v MAX XR Brushless High Torque 1/2" Impact Wrench with Detent Anvil (Tool Only)

Instead of getting a big, loud, expensive air compressor that you have to start up and wait for pressure to build, and have to drag it/its hoses around your garage, just get a cordless electric impact wrench. In fact pretty much all air tools have better electric versions now. I have one of these and I have used it for giant suspension and brake caliper bolts and spun them all off instantly: https://www.amazon.com/DEWALT-DCF899B-Brushless-Torque-Impact/dp/B00WJA1J68

I hear the Milwaukee 1/2" one is great and everybody recommends it for a little more money.

Mine come off easily with an impact wrench. Here is mine, which gets a lot of use...

And if you remove the fans and radiator there is plenty of room to work. One pull of the trigger and that bolt is spinning.

No. You want a Dewalt (or milwaukee if you're into that sort of thing).

Yeah you're right it's 700 ft/lbs

That's an impact driver, not an impact wrench. I don't know that model but they generally put out about 100 ft lbs. You need something like this.

Cordless impacts FTW. I only have the Craftsman C3 20v and it's still pretty great. Takes a second or two on stupid-tight lugs (for example, whoever put the lugs on my buddys RAV4 should get a talking to - no way you'd ever get those fuckers off on the side of the road) and the wheel-hub nut on my wife's Odyssey, but it works. I've decided the money I'd spend on a bigger compressor is going to go to a small quiet one and the beefy DeWalt. If 700 ft/lb can't do it, I've got no business screwing with it... ;)

I use this

No need for a compressor and o lines to fuck with or oiling. It's great and hasn't let me down yet. In fact it outperforms my craftsman pneumatic impact

Alright, no offense to the first commenter but we need to clearly define what we are talking about.
There isn't an "impact driver drill" I believe your talking about something like this that is a cordless electric 1/4" impact driver. It accepts 1/4" hex driver bits notice the special cut out at the base of the bit, that's what keeps it from falling out. It functions like a drill/driver until it encounters sufficient resistance then it impacts, giving increased torque(rotational force), it does not produce a hammering force(along the axis of the bit).

Now this is an impact wrench it too functions like a drill/driver until it meets resistance then it impacts adding rotational force but not hammer force. What are the differences between this and the driver we looked at earlier? First is obviously size, the wrench is bigger, and stronger, and heavier. But that's not what makes it a different tool, what makes it different is the tip, it's a square, like for putting sockets on, in this case 1/2" sockets but they make 3/8", 1/4", 3/4" and much larger!

So could you use the first tool in place of the much larger second tool? Yes! Use one of these adapters

Here's the problem tho, the first tool, the driver, makes at most 117 ft-lbs, and I believe that's stretching, the second tool, the wrench, makes 700 ft-lbs. To remove a rusty, crusty, stubborn lugnut you will need the bigger badder tool, sometimes it still won't be enough, and you'll need a breaker bar with a cheater pipe.

Now what the other commenter mentioned, the hammering force, that can be made with a few different tools. Let's start with the handheld impact driver yes it's confusing, two different tools, both called impact drivers, but this one we'll call the handheld, you hold it with one hand, and hammer it with a hammer. It has a cam mechanism that takes some of that axial force and imparts a slight (like 1/16 of a turn) rotation. It's good for stuck screws especially Phillips heads.

Another, more common tool is the hammer drill it is essentially a drill, it grips with three jaws onto the same bits as our first impact driver, or onto completely round bits, like your common drill bits but when you engage the hammer mechanism it will push its chuck forward and back rapidly, and the pressure you apply to the back of the drill hammers the bit into the material your drilling, useful for concrete/masonary work. But for real drilling power into concrete you want an SDS rotary hammer drill this bad boy only accepts SDS bits, provides it's own rotary and axial forces and will drill thru reinforced concrete like non reinforced butter.

Ok I think that about covers it, if anyone would like to add on I'd appreciate it. And remember:

Always use the right tool for the job, a hammer is the right tool for every job, and every tool can be used as a hammer!


Obviously that was sarcasm.

Is this the one you would recommend? :

This one is advertised as making 700ftlbs.
