Lots of Power
Rating: 5
I bought this impact thinking it would be good for doing small screws like cabinet screws, but I use this for everything. This impact has no problem driving in 3 to 4 inch screws like deck screws. It's lightweight and small enough to fit into a tool pouch.

small and pacs a punch
Rating: 5
I have had this little driver now for 6 months and can not be more impressed. I thought I would use it just for quickly removing small screws but this tool will drive and remove large screws from tough hard to reach places. Really packs a punch for its size.

This is a very compact and powerful driver. Easily fits between joists and studs and has enough power in one battery to drill dozens of 5/8" holes for romex thanks to the two speed gear box. The clutch makes the driver great for quickly mounting cover plates without damage. If I only had one it would be this. The only improvement I would make is a battery level meter like the impact driver.

Great drivers, even better support
Rating: 5
At work, I bought this drill driver for installing self-tapping sheet metal screws in ducting and appliance repair. Worked great... bought another & then another. Accidentally dropped one 12' on concrete... still works! Over worked one and it burnt the circuitry. Bosch promptly repaired under warranty & returned. Compact power compared to other small drivers. Tool fits a niche; more finesse than a larger drill/ driver. Still have 18V for big stuff.

Best screw gun yet!

I've owned this gun for over two years and it's always the first tool I reach for in practically every project around the house. I've yet to find a job it won't do.

GOOD TORQUE, BUT WHY IS THERE NOT A MAGNET IN THE 1/4 CHUCK. THIS IS A SCREW GUN IT SHOULD HOLD THE SCREWS. DO I HAVE A LEMON OR ALL PS 21'S WITHOUT MAGNET

good for crafts, not for work
Rating: 3
Nice driver with needed features but one battery won't power the driver long. If you plan to run a lot of screws or drill & tap a lot of holes then this line of Bosch power drills/drivers is not for you. Poor battery capacity !!! Plan on always charging your next battery while you are working because you'll need it sooner than later. If all you need is a drill for crafting then these will do. They fit the hand well and are nice to use... until they run out of juice.

I am now on my second DCD991 hammerdrill/driver. I just purchas the bare tool because I have multiple 9ah batteries in my toolkit. This drill is a workhorse. I use it daily. Mostly for drilling holes through steel, concrete/brick and in a very oily, dirty environment. This drill holds up to all the obstacles thrown at it. I have never had a problem. I recommend the flexvolt 9ah batteries, the lanyard and belt clip.

Very Durable
Rating: 5
I have had almost every name brand high end drill out there over the years and this one has been the best hands down. The power is untouchable by any other I've used. It's been extremely durable and with the 5ah XR battery it last all day and can drive large deck and framing screws without even a hint slowing down. Best drill I have ever owned. Definitely recommend DeWalt 20v XR drills. [This review was collected as part of a promotion.]

I've owned a dewalt still for 10 years and finally decided to upgrade. What a great investment. Can't wait to use this new drill for another decade. [This review was collected as part of a promotion.]

No Nonsense Brushless American Drill
Rating: 5
I scored this drill new for a song and it's held up great. Don't waste your money on the hammer version - if you actually need to punch a hole in concrete SDS+ is the way to go. This drill also has a very nice light (same feature I later found on my Mac Tools (DeWalt) 20v 1/2 High Torque Impact) except here you get different duration of spotlight, as opposed to torque settings. Also, the lower "2nd" speed is nice, I wish my DCD777 had a range between 1st and 2nd for times when you're drilling smaller holes in softer metals and can pick up the pace a bit. 10/10 overall, very pleased. Hopefully I can get quite a few more years out of it.

Great drill for home and work
Rating: 5
I bought this drill about 5 years ago. It still runs today like it did when I pulled it out of the box. I went with Dewalt because my uncle bought a combo set of Dewalt drill, impact, circular saw, and reciprocating saw 15 plus years ago and still uses them today. Even after all the heavy use and abuse they have endured it amazes me that they still perform. [This review was collected as part of a promotion.]

Good machine worth every penny
Rating: 5
I've had my drill for a while now maybe going on three yrs I've lost track. It is rugged easy to use and powerful. Im not a big fan of the electronic clutch but it does its job. I prefer the old still clutch. Im sure this clutch is designed so you don't burn out the motor but it can be annoying when driving larger lag bolts. All I hope is that dewalt stops redesigning their batteries, I'm getting tired of buying adapters just to use my older tools. I do recommend this drill it's built to last I've dropped mine from roof tops and it has never failed not even a crack and barely even scratched it; not recommended but nice to know it will hold up.
