How many foot lbs does this produce? tia.?

152ft-lbs, according to Dewalt's website. Enough to injure your wrist if you're not prepared for the power. It's an awesome tool!

What's the difference between this and the 885b non xr?

The 887 is much stronger as well. This one has 1800 inch lbs of torque which is stronger than any other brand's impact driver (except the kobalt 24v but it's much lighter than that one) What the power means is that it will drive a large lag bolt quicker and smoother than other brands which will struggle to do the same job Don't even consider brushed version. The brushless are more powerful, more energy efficient and made in USA. They only cost a little more so not really a benefit to get the 885

What type of adaptor is needed for socket use with this impact driver?

You can purchase on here 1/4" hex to socket adapters for 1/4,3/8,1/2" sockets. However, this is not an impact wrench, it is an impact driver. So you will have no problems using this for basic socket tasks, but you would not want to try and change a tire.

Is a dcb205 battery compatible with this driver?

Yes, all 20v battery wether it's 1.5, 2.0, 3.0, 4.0 or 5.0 ah battery works
