Another handy tool
Rating: 5
Finished up another home remodel project with this tool. It's compact takes on all drilling challenges up to the chuck capacity. Like all the Bosch tools it's power packed and you can always count on them to deliver. Have several of the compact 12v tools not a one disappoints. And the fact they all use the same battery is awesome!! Go Bosch.

Compact size with more than enough power!
Rating: 5
I bought this compact drill for my work. Small size with enough power to finish HVAC job easier and quicker. Battery charges fast. It will be interesting to try one with hammer drill function. For intensiveness of the work, most our power tools are not going to be last got couple years, so 3 year Warranty on tool and 2 year on battery will be plenty to cover.

Perfect drill for cabinet shop.
Rating: 5
After 40 years using all sorts of drills in my cabinet shop, I bought this Bosch PS31B two years ago. It is the perfect drill for a custom wood shop. It is small and fits nicely in your hands. The clutch is accurate even with very light settings for things like hinges, door handles etc, yet powerful enough to drill large holes in tough wood like oak and maple. The batteries last and are fast to charge. Two speeds are handy to have as well. About the only improvement needed is a method to hold extra bits in the handle. This is the perfect drill for cabinet shop, also electrician, appliance repair and so on. Highly recommend this drill.

Durable and Light Weight
Rating: 5
Purchased this little 12V drill for a specific commercial project. Needed to drill over 1,000 holes (5/16" diameter) through 14 gauge steel, overhead at 9' high. (I didn't want to use a full size cordless drill, as operator fatigue and workspace limitations were big issues). The PS31 performed the job flawlessly! It had enough power and decent run time between charges. I was so impressed, I just purchased a 3 tool set (#CLPK32-120) that has the drill, an impact driver and reciprocating saw.

Good Drill
Rating: 5
I bought the PS41-2A last year to go along with my old corded Bosch drill because I need the impact feature. My cordless 3/8s drill has served me well for 20 years but since I already had the two batteries with my impactor I thought it was just dumb not to have the PS31-Bn to go along with it. I'm very pleased with it as well. As a lot of my work is installing cabinetry, the small size is perfect to have in the tool belt. Batteries last forever and plenty of power for 90% of drilling. Will be looking to upgrade to brushless at some point needless to say.

Totally pleased
Rating: 5
Small size was my primary goal and the 12 volt PS31 drill is perfect.  I've gotten along with my old power drills for at least 30 years, so the new features of the PS31 are like skipping a couple of generations.  I stayed away from battery powered tools before now because I didn't like the large size of the battery pack hanging off the bottom.  The PS31 is smaller than all my old power drills and way handier.  It is so user friendly, I felt safe in helping my eight year old granddaughter use it on her science project.  She was thrilled with her success. I am so pleased with the PS31 that I have now purchased a Bosch PS60BN 12-Volt Max Lithium-Ion Pocket Reciprocating Saw.  The fact that the saw uses the same battery and the quality of the drill are what motivated my purchase. I was a little confused by the Bosch tool registration web page, but apparently picked the right drill model number. Great tool.

Compact but powerful
Rating: 5
I already have a bunch of 18v Bosch cordless tools, but the 18v drill is a bit heavy for odd jobs around the house. This little one gets into smaller spaces and is powerful enough for all but the biggest jobs. For those I am keeping the 18v drill. I got it with a kit, CLPK22-120AL, which included the drill, the PS41 impact driver, a L-BOXX 1 with inserts for both, a charger, and 2 BAT414 batteries, the new 2.0 AH ones. A huge bargain, especially since the kit comes with an extra L-BOXX 1A for small parts. The drill works great with my twist drills, up to 1/2 inch (the chuck is 3/8 and the larger bit has a 3/8 shank). It goes through 2x4 and plywood with no problems. Not quite enough torque for spade bits, but the impact driver handles that just fine.

Perfect size
Rating: 5
I've been out of the cordless drill market for several years. When I remodeled my kitchen I needed something for hanging drywall, cabinets and securing the counter tops. After looking at several of the new Lithium Ion drills, I really liked the feel and features of the Bosch. It is compact enough to get into the tight corners of the base cabinets to secure the counter top, and hanging wall cabinets, won't tire your arm out like bigger / heavier drills. This is by far the most compact and best fitting drill I looked at.

Light and strong, but drains the battery fast
Rating: 4
It's really light and comfortable, especially in tight places, and has a lot of torque for such a small drill. But there are noticeable drawbacks: the battery drains pretty fast, the speed switch is somewhat clumsy (sometimes you think that you switched the speed, but you actually didn't), the chuck's plastic is too hard and slippery. The charger is specified as 30 min charger, but it actually takes about an hour to charge fully drained battery. Also, for such a price it would be good to include a few accessories (bits etc).  I have had the drill for a month now, so cannot comment on reliability at this moment.

Great for light use
Rating: 3
We have several of this drill in our workplace. Very compact and light drill. Handy that it comes with 2 battery and charger. However, we use it very heavily on a daily basis and several of the drill died after only 5-6 months. Seems like the motor died. However, Bosch have it repaired under warranty. So, I am still wondering if this drill is for heavy use or not.

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.]

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.
