I bought this drill kit about two month's ago and so far it has performed very well on the job.
I was somewhat concerned to find that even with the fairly high price tag the drill and batteries are both being made completely in Mexico. From my experience, this usually results in a noticeable drop in quality. I suppose this is just a sign of the times and I should be getting used to it by now.
Also, after years of waiting for Dewalt to produce an 18V RAD unit, I still feel somewhat let down by the fact that it only has a 3/8" chuck capacity, especially since almost all of the trades really need a good 1/2" cordless RAD. The 18V RAD that Milwaukee makes is virtually useless and this Dewalt drill could probably spin a 1/2" chuck under most realistic workload conditions.
The two NAFTA batteries included are marked only as XR, not XR-Plus as all recent Dewalt 18V batteries manufactured in Japan are. I'm not sure if this means anything, but it did catch my attention.

And now the praise...

I have owned the almost identical DW966 14.4V version of this drill for several years and it has been worked hard but was always underpowered for heavier drilling tasks such as boring holes in 2X studs and joists or drilling into wall cavities from a basement or crawlspace below or an attic above, even when using spade/paddle type bits. Although the owners manual lists the maximum hole drilling capacities as the same for both the 14.4V and 18V, the new 18V DW960K has 100 inch-pounds more torque and several hundred more RPM's in high speed than the 14.4V model and is much more at ease with the type of heavier work described above. This drill will never replace your corded RAD for continuous heavy use on larger jobs but is great for smaller jobs where you need to drill several holes and don't want to waste time dragging out an extension cord and hunting for a distant electrical outlet. The added cordless advantages of mobility and safety are especially important when working in a damp crawl space or cramped attic area. The DW960 is only slightly larger and just a little heavier than the older 14.4V drill so it can still easily get into the tight places for drilling or driving screws but has lots more of what tradespersons need most, that being, torque and speed with the ability to interchange batteries with all your other DeWalt 18V tools. Overall it seems to be a well made tool and all is fine for now, but I can only wait and see if the NAFTA product durability will be equal to or better than my older Dewalt drill.

Review : This tool worked great for about three months, then while driving a#10 sheet metal screw the trigger froze in the on position, smoke started coming out of the battery pack, the only way to stop it was to disconnect the battery. I'm a cabinetmaker and this is one of the better right angle drills I've owned, it's a bit heavy and the forward and reverse switch is hard to use. The batteries last a long time, I can be on the job all day without charging them,nice.The keyless chuck is one of the best I've used, I hope this is just one of those lemons you get every now and again because I was really begining to like this tool.

Review : I recieved my new DW960k heavy duty cordless drill driver 20 Nov. 03. The next day, FRI. 21 Nov. I took it to work to try it.I put a newer fully charged battery in the tool, there was an imediate bright spark within the drill and it began smoking heavily. Once the fire went out I put a battery back in the drill and now it runs full blast without squezzing the trigger.
I have tryed to contact 1-800-4-dewalt but they aren't answering the phone. It appears that it is better to purchase your tools where they can be tested. I now own every 18 volt cordless tool that dewalt makes, several of some, and I wonder what I am going to have to go through to get this drill replaced, not repaired. I did not purchase a reconditioned tool.
