DEWALT 20V MAX XR Hammer Drill/Driver Combination Kit with Power Detect Tool Technology, 1/2 Inch, Battery and Charger Included (DCD998W1)

I have the DCD996 and now this DCD998W1 power detect hammer drill/driver. While I can not talk negatively in anyway on the 996, but this drill is definitely a refined upgrade to the 996. While they both share a similar look and feel, the 998 looks a little more polished and feels a little more comfortable in your hand. But the biggest difference is in power, side handle, and sound. This drill seems quieter, while being much more powerful. It also seems to have better air flow which seems to keep it cooler vs the 996 while doing the same tasks(ie mixing 60 lbs of mortar mix in a 5 gal bucket) using two 8 ah batteries, one on the 996 and one on the 998, the 998 can run longer and perform more work on one charge vs 996. So there seems to be some advancement in energy consumption. This is now my most favorite drill. It's definitely a good upgrade, especially if you need max power and efficiency. Btw it's still loud in hammer drill mode, but when you have to drill a few dozen 3/8s to 1/2 inch holes for rebar or all thread it's worth it when your buddies drills are quieter but much slower. I'd buy this drill again in a heart beat.

[This review was collected as part of a promotion.] Years ago, my wife bought me a set of 20 V Dewalt tools which included a hammer drill. I used it for a very long time and when the lithium batteries came out I debated upgrading for years. When finally it was time to pull the trigger, I sold all of those tools (which were still working just fine) and replaced them with Bosch. I was so disappointed at how much less power these newer tools had. Quickly I sold all of the Bosch stuff and returned to Dewalt. I bought each separately so I would get more batteries. This is the best trail by far I have ever around. More powerful, relatively light weight and all-around better than everything else!
