So I have two DW056 impact drivers (1/4" hex).  The discontinued DW057 is an impact wrench (1/2" drive).  I am contemplating converting one of my DW056's into a DW057.

I was on the Dewalt website and looked at the exploded diagrams and parts lists of the DW056 and DW057.  Looks like it is just the anvil that is different.

I know that the torque would be considerably lower than a DC820, DC821, or DC822.

Any thoughts?  Anyone with experience on this?

I did a conversion of a 14.4v  DW054 with the collet. In looking through the Dewalt pics I found they had a 12v 3'8" square drive with a hog ring retention for socket. All the other pieces including the nose were the same number. 14 bucks later I had a 3/8" impact as they did not have one at the time. The 14.4V 1/2" DW055 uses  a different nose piece and was not a good candidate.

What's really great about this site is not only does this show you the only manufacturer diagram, this goes into exceptionally great detail and you can even buy parts as well. 

 I'd like to be able to provide more help, but this is the best I can do as  I've never even used either drill before.  Hope I helped.

Thanks for the info Russ.  I ended up keeping the two DW056's as they are and bought a DW059.  With three impacts I have far less frequent bit changes on the jobsite.

I am more than happy to help and if you ever need help with finding tool diagrams again, that site is one of the best ones I've found.  No offense to Dewalt, but if your product is discontinued then more often than not, your out of luck for very detailed information, parts and how it install some of these parts.
