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.

Happy Mothers Day Indeed!
Rating: 5
This was my gift for mother's Day! I was so excited when I opened the package and found that it was a not only a drill but a Milwaukee hammer drill!!! I am not a professional but we are remodeling our home either to sell or to increase the property value. I have been doing all the work myself and have become quite good at it. This product has made it so much easier. and the hammer drill part I mean to be able to screw into concrete without killing myself is quite a feat thank you family for giving me the best gift ever. Looking forward to my next power tool to add to my ToolBox the M18 Sawzall! Oh and the product runs great, lightweight and 2 battery packs!

Gr8 Tool, I am a DIYER and I got the same results as my 18v
Rating: 5
Quick review : Views from an active DIYer I love the hammer drill , everything that I was able to do with my 18v tools. I got accomplished with the 12v little brothers. Having lightweight tools reduces the load and strain and is sure to add longevity to your work life. More In depth review: Hammer Drill: To switch the Drill/Drive mode you have to rotate the collar past 16, there are rubber molding by the hammer icon on the sides I initially thought that was how you switch the modes, by pressing it. That was not the case. For my needs the Hammer drill worked well. I used it with landscape timber, 2x and I had no problems at all. You can adjust the torque settings and when it reaches its maximum torque you can hear it powering down and it stop altogether. You have to release the trigger and press it again if you want to continue. This is good to ensure you do not over tighten a screw

Gr8 tool, did not feel weak at all
Rating: 5
Quick review : Views from an active DIYer I love the hammer drill everything that I was able to do with my 18v tools. I got accomplished with the 12v little brother. Charge time right out of the box with the included charger was pretty long, 1/2hr for the 2.0ah and 1hr for the 4.0ah. Having lightweight tools reduces the load and strain and is sure to add longevity to your work life. More In depth review: I used this for a few projects I had , I used it with a pocket hole jig, T-Star bits and regular bits. The drill worked fine. Every thing that I was able to do with 18v tools was able to do with these also. I got this because of the expansive M12 line and there are a lot of tools I am interested in. The batteries do not have a fuel gauge but the drill and impact driver did. Once you press the trigger the fuel gauge will stay on for 2 seconds. The LED light stays on for 10 seconds after the trigger is depressed. I found the light to be bright enough to light my work area. This comes with the belt clip attached on the left side but you can remove it and place it on the right side if you are a lefty. To switch the Drill/Drive mode you have to rotate the collar past 16, there are rubber molding by the hammer icon on the sides I initially thought that was how you switch the modes, by pressing it. That was not the case. For my needs the Hammer drill worked well. I used it with landscape timber, 2x and I had no problems at all. You can adjust the torque settings and when it reaches its maximum torque you can hear it powering down and it stop altogether.

great tool, but it's got some draw backs
Rating: 4
I'm in general aviation so I prefer a high rpm, good trigger modulation and light weight/compact. I love this drill, however if you plan to use this drill for a lot of low torque fasteners as I do then you'll find the electronic clutch inferior to a mechanical one and the slow start at lower clutch settings extremely annoying. Also the chuck will spin the whole drive train before you can get a proper clamping force on the bit. Again I'm I general aviation so 90% of the work I ask this drill is a 1/8th inch drill bit in 2117-T4 aluminum. For my work it's great when you have a lot of rivets to drill as I frequently do. But any work that you rely on the clutch, get the older model with a mechanical clutch. I use a bosh ps22 for inspection panel fasteners and the Milwaukee for drilling rivets on all the sheet metal repairs that as an employee of a flight, school is often.

This is a good drill.
Rating: 4
So I work in construction. I have 2 battery hammer drills. This and an old 18v xrp. Now obviously the xrp is more powerful, but this 12v is lightweight, compact, easy to use, and is faster at small 5/36 drilling. I like this drill. The belt clip works better than the old design, and is now my go to drill. But I do have a complaint. The exhaust ports are in the worst spot. With long term drilling there isn't a place to hold it with my other hand without getting burned.

Hmmmm ?

No doubt a great drill but in hard working apps such as brand new sharp drill bits drill in steel and get caught up it stops making it very hard and longer to push the bit through. Good luck
