Bosch PS21-2A 12V Max Two-Speed Pocket Driver Kit with Batteries & Charger

This is my absolute favorite screw driver for electronics and computer repair. I paired it with a 6 inch Philips bit that I just leave in it all the time. (see pic) My rule: If the bit is too big for the screw, Use a precision hand screw driver. If it fits, Save yourself some time. Set the clutch and watch your work go faster. The reasons this is amazing for repair work are the light weight and small form factor, The excellent reach and visibility with my long bit, and most importantly, the speed that you can tighten or loosen screws coupled with the clutch, which when set on 1, does a beautiful job of preventing over tightening, which can damage delicate equipment. I can tighten a screw at full speed (speed is similar to a cordless drill or impact driver) and the clutch will make sure the screw is tightened perfectly. Leave those miserable little pen style screwdrivers off your list. Forget the clutchless drivers that spin so slowly that you want to kill yourself waiting for them to finish. (Most small screw drivers will leave the clutch off. Don't be fooled! You need the clutch.) Forget using a full sized heavyweight drill/driver. Trust me! This is the tool for you! (for those who may not know,. the clutch is the dial at the business end of the screwdriver with the numbers on it. It prevents overtightening by disengaging the power/torque when a screw is tightened to the desired amount. 1 is least tight 20 is most tight See the attached video. The clutch stopped the screw from being overtightened even though I held the trigger for too long. You can hear the difference in sound when the clutch kicks in) This thing is legitimately perfect. The battery lasts me for months and it comes with a spare! The price is reasonable, It has abundant power, The grip is great and it comes with a soft case. I also use this for light wood work. It does not struggle driving a 3" screw into a 2X4. It excels at making flat pack furniture builds painless (Ikea furniture) Ikea will tell you no drills. With the clutch set at 2 or 3, it will tighten perfectly and safely every time. (start the screws with your fingers first and tighten with the Bosch so you don't strip out the threads) I love this tool! I have had it for several years and it's one of my all time favorites.

I bought one of these along with the very similar drill version in Dec 2013 for use in my commercial shop. It is now Nov 2024 and both are still being used regularly INCLUDING the 4 original batteries. This driver has received almost daily use for 11 years and is still working great. I've had a lot of cordless tools over the years and can't think of any where both the tool and batteries are still good after more than a decade of use. This is an absolutely outstanding tool. The feature that often gets overlooked on something like this is the accuracy and sensitivity of the clutch. Most drills do not have a clutch that can be reliably used on small screws without stripping the holes. This guy can drive even tiny things like #6x1/2" screws in soft wood all day long with the perfect torque. It is small enough to fit in tight spaces; the lack of a chuck combined with a short bit make the overall length very short. Despite being lightweight and compact, it is extremely durable and never feels fragile. It has a nice fat grip that fits perfectly in the hand. The trigger pull allows for a wide range of speed variation for good control. The batteries, despite their tiny size, last a really long time. We frequently use it with a 1/4 or 3/8" socket adapter to quickly thread fasteners in or out during assembly operations. A couple years ago we replaced all of our cordless drills with new 12V brushless Milwaukees. I love the power and high RPM of these units. However, they now have an electronic rather than mechanical clutch. That clutch is absolutely worthless on almost everything. It basically cuts the power at a specific torque, which sounds great in theory. But unlike a mechanical clutch, it doesn't instantly stop the torque. The spin-down time of the motor before full stop means that unless you're going really slow, anything you'd want to use a clutch on will strip out before it stops turning. As a result, this Bosch driver has become even more popular as the brushless Milwaukees are now exclusively drill-only use. Now I'm back to buy a few more of these driver and would highly recommend them to anyone who needs a quality clutch for their operations.

Several years ago I received, as a gift, a kit comprised of a Craftsman cordless drill and screwdriver. The drill has performed admirably, and the 19.2 volt batteries seem to be up to par, even about 12 years later. The screwdriver was a small, 3v affair that was "OK", and was useful for a few years. But the battery deteriorated, and within the last 12 months or so the battery wouldn't hold a charge at all. So I went on a hunt for a high quality, reliable cordless screwdriver. I did a lot of reading of reviews, not only on Amazon and other retail sites, but on forums for construction professionals and serious DIYers. The consensus seemed to come down to Milwaukee, Makita and this Bosch. The only consistent criticism of the Bosch was that the guide light does not come on prior to the drill starting to spin. This is not true. With VERY gentle pressure, the light does come on before the spin up. Yes, it is tricky do get just the right force to accomplish this, and yes, I think Bosch could have done a better job of implementing this feature. Is that worth the deduction of a whole star? No, not in my opinion; others may differ. This driver pretty much does everything else right. The size and form factor are great. The weight and balance seem to be perfect. The torque control is, at least in my experience so far, excellent. Shipping with a spare battery is more than a nice touch. The only other things worth mentioning regard the carrying case. It is large and well made, but the straps that hold the driver and spare battery in place don't really do the job. In other words, the interior seems to be haphazardly designed or perhaps designed for some other tool. So far on a few small jobs on which I've used this driver, it has performed flawlessly. As mentioned, the torque control is very good, and speed control is equally excellent. I am expecting many good years of service, and at this point feel the price represents great value.

Yes, I just bought one..... Why? I gave my old one to my daughter because it was easier to give it to her than check my luggage to bring it home. After all the years of use, it still worked like a charm. This one has the exact same feel as the old one... and the batteries are interchangeable with the older model - which gives me 6 batteries (not that I ever need all of them....) I have three of this series of tools.... an impact driver, an adjustable angle head drill driver, and this tool. The batteries are interchangeable.... and they last. My only caveat is don't run the batteries down to zero charge so they overheat and keep them inside when not in use so they don't freeze or get hot. Also... don't leave them on the charger. Charge them up and take them off. The compact size of this tool is it's most obvious feature, but it's also powerful. I used the old one to completely remodel a house... one screw / hole at a time. It fits into other places where a larger tool will not.... drawer glides, hinges, inside drawers to mount the drawer fronts..... and where it doesn't fit, my adjustable angle head version does. The impact is plenty powerful and I prefer it to the Milwaukee that I have. The speed trigger is more sensitive on the Bosch.... the Milwaukee -- although variable speed - seems like it's pretty much on/off - not the slow buildup required for certain applications. Overall, I think this is a great tool.... if I didn't, I wouldn't have bought another one.

Note: The model name of this line of Bosch screwdrivers/drills is "12V Max." Not be confused that 12 volt is maximum power or whatever. I have been using battery powered screwdrivers for about 25 years. (Some powerful enough to use as a drill.) I decided to update my screwdrivers because 1) My old beast of a screwdriver pooped out, would not hold a charge, and batteries were no longer available for it; and 2) My Black & Decker (four X AA battery powered) cordless screwdrivers could handle many jobs, but those drivers are not powerful nor versatile enough for bigger jobs (e.g., driving large screws into 2 X 4 or thick plywood). With this intent I went sniffing on Amazon and YouTube to find the best screwdriver suited to my needs and requirements, that is, for DIY household use, not for a profession (e.g., carpenter, plumber, contractor, electrician, handyman). While researching and shopping I could simply have stuck to the professional drivers/drills, you know the names. A sticking point, however, I didn't want to pay $150 to $200 for driving screws every now and then, or drilling a hole every other month, if that. Moreover, I have small hands (glove size is always men's small). While the big drivers are impressive beasts, my mini-digits get tired of holding those, especially if overhead or arms extended. Yes, in these situations SIZE DOES MATTER. What sold me on this Bosch "12V Max" screwdriver / drill (PS21-2A): - High ratings, solid reviews on YouTube and Amazon. This screwdriver received high marks everywhere. Yes, there were occasional complaints, but if product star ratings on Amazon indicate an average of four stars or higher, a few scattered complaints don't factor into my buying decision. (And often times those complaints border on moronic, stupid, or nonsense. E.g., "After five hours straight use on a house remodel I was doing the battery crapped out.") - Compact size: If you're looking for a small lightweight, but nevertheless powerful battery powered screwdriver, this Bosch does not disappoint. At age 67 I'm in reasonably good shape. But I'm not fooling myself. I can no longer comfortably use manual screwdrivers, and I definitely feel the pain when holding extended or above my head a large heavy power screwdriver. When I read that this driver was very compact and lightweight I no longer would settle on even a mid-sized screwdriver. (See my pics, comparing the size of this screwdriver next to U.S. dollar bills.) - Two batteries: This was VERY PLEASING to me, that this kit comes with two (02) lithium ion batteries. Plenty of power for all-day DIY jobs. Warning: What some companies do to market their consumer screwdrivers at a low consumer-friendly price is to sell the powered driver SEPARATE from the batteries. You have to buy the batteries separately, or buy the higher priced set or kit that includes a battery and charger. Pleasing Price: My budget was $60-90 for a screwdriver, battery, and charger. Because it totally sucks to run out of battery power, I allotted another $30 to purchase an additional battery. So I was super pleased to see the retail price for this device was $80 for the screwdriver, TWO (02) lith ion batteries, AC charger, carrying case, and a couple bits. With free Amazon Prime shipping, I was at $40 UNDER budget. Note: I never buy on price alone. E.g., eBay and Amazon are littered with $30-40 trashy as-seen-on-TV screwdrivers that include battery. Bonus Tip: You may rest easy because El Cheapo branded screwdrivers are guaranteed: "[W]hen charging your battery it is warranted to catch fire and burn down your house." Quality Name: I trust the Bosch brand, even though like everything else, this driver is Made in (Asia). Despite that, to protect its reputation for quality and the Bosch name the brand represents, I assume in Bosch has strict quality controls. Recourse: I liked the fact that buying from or via Amazon gave me access to a full refund if I didn't like the product, or simply changed my mind. Functionality and Features: The 12V Max has everything you want in a drill or screwdriver. Has the power to drill most anything, or to drive/remove the biggest screws in the hardiest of materials. This is what I would call a "precision driver." Features that stand out: - Small, compact, lightweight. - Smooth precise motor and driver gearing. - Speed control (via the trigger switch). - Precision power controls: A two-speed switch; the trigger (the more you press, the more power delivered); and the clutch (1-19, and drill setting). You can set this driver/drill for delicate work, or place everything on full power for the big tasks. - Note about the Clutch (settings 1 to 19, and drill mode). "1" is lowest, "least power" setting, "19" is highest, "most powerful" setting. For max power dialing the clutch to the indicated drill bit icon. Bonus Tip: Why the clutch? You use the it to prevent stripping screw or bolt threads, or damaging the head (e.g., stripping the slots), or damaging the working surface. E.g., on a "1" setting the driver will lightly screw or unscrew the a bolt, and make a clicking sound to show the driving has stopped. - Quality throughout: The fit and finish of everything in this kit is finely done. This is NOT your cheap plastic, poorly fitting, breakdown-in a-month-screwdriver. - Lot of Nice Stuff: Included in this kit is the screwdriver, two batteries, an AC charger, canvas carrying case (that holds everything), two hex-head screwdriver bits, and easy-to-read manual. The LED light is a nice touch. I actually used the light to see inside an car engine bay when removing a part. - Note: This screwdriver uses hex-head bits. This makes it very easy to attach and remove bits. If you have standard drill bits you want to use, you can buy a hex head adapter that has a drill chuck for standard drill bits.

I got this at a bargain price of $79 inclusive of delivery during the last sale. This will be my dedicated PC repair driver. It's small head size means it can get into some really tight places and the fact that it has a clutch means the chances of me stripping out screws is near negligible. With a set of good bits this practically halved the time it took to strip and re-assemble a custom desktop. Some baulk at using a powered driver with magnetic bits on desktops thinking it's a recipe for disaster but I have never had any issues doing it this way. Will it drive? Yes... but I doubt it will do a good job without an adjustable chuck. ++Pros++ -Trigger and RPM ramps up smoothly. Just the right speed for my needs with the ability for finesse work -Battery lasts a loooong time and the 1.3Ah is really affordable right now -Rubber everywhere that counts; a short drop onto concrete wont kill it unless it lands on the chuck or the battery -Handle is surprisingly comfortable even for my tiny Asian mitts -Bright LED --Cons-- -Decals on both batteries were peeling off right out of the box (minor issue but worth mentioning) -No power level gauge on this tool (I knew this before buying which is why I won't knock any stars off) -Gear lever is stiff (minor issue) -2 X 1.3Ah batteries were included instead of the newer 1.5Ah ones (there was no mention of this in the listing) - docked one star At US$79 (sale price) this is a great buy but I feel the price on this can be lower. Would I buy it at it's current price? Unlikely. If you have the 10.8V drill and impact set from Bosch I see no reason to get this, even if it was a bare-tool unit. The drill and impact driver will do what the PS21 will do and they will do it better. If all you need is to drive small screws all day then the PS21 is the perfect tool for you.

Perfect hex bit driver and drill with two switchable speeds! It doesn't compare with my Rigid impact driver, but that's not why I bought it. It's the perfect all around tool for most everyday things like screws, drilling, and nut's and bolts etc, yet has the power to really snug things up or break 'em loose for what it is. Again, it's not an impact driver. It's a screw driver on steroids and does a fine job at drilling and general wrenching and makes for an acceptable replacement for the air-ratchet in the garage too. Again, it isn't high torque like an impact or even an air-ratchet, but it does well with most things and will certainly snug your nuts and bolts up in the garage. You're going to use a torque wrench to finalize things anyway, right? It's fast becoming my go-to driver because it's lite weight and compact enough to fit nicely in the hand and get in places my full size power drivers and impacts can't. Batteries seem to last a long time. Of course you should always have backups and aftermarket batteries for the Bosch line of power tools are cheap and last just as long! I own a BOSCH PS11-102 12V Max 3/8 inch right angle Drill/Driver as well, and between the two of them I couldn't be happier! I can get everything I need done except the heavy duty stuff, which is why I have the Rigid tools when needed. I love my Bosch power tools and would replace them with new ones in a heartbeat if they came up missing. They fit that niche between the little 3 and 4 volt electric screw drivers, and the 20 volt heavy impacts. Another thing about Bosch that I noticed, is the cases that come with their power tools are roomy enough to put a few extra bits and batteries in so you don't have them hangin' around in your truck or tool box, but small enough to carry to the job site without needing a wheel barrel or a forklift. Getchya some needed Bosch power tools. Ya won't send 'em back! ;-)

Lightweight and small, still pretty powerful. I like the prcecise speed and torque control.

Muy bueno para uso donde se requiera poco peso y muy funcional en espacios pequeños.

Best drill for one hand use- light and can be used with one hand. - cant imagine being without it

It took me a long while and a lot of research before I chose this specific compact drill/driver. I had a list of specifications that I wanted met which had narrowed the list quite a bit. I find this tool to be about as perfectly balanced and sized as anyone could want. This has a size compact enough for a woman or a child to use easily also with their smaller hands. A problem I have heard from my friends and people teaching kids to use power tools safely. The tool is robust and the clutch actually works, which is more than I can say for many other cordless drivers and drills. The dual speed gear setting is an absolute MUST for anyone choosing such a tool. Also you will want to invest in a good set of 1/4" drive bits and accessories. There are many quality ones to choose from. I use this tool primarily for assembly and disassembly on electronics devices so the fine and precise speed control was a must also. Most tools this size do not have enough torque to safely apply power to small screws. Cheaper (less quality) tools will require you to squeeze the power trigger more than you need which often strips out the bit or screw heads. The Bosch PS21-2A has plenty of power and so you have adequate control and stability when performing precise jobs. I give this tool a full FIVE STARS!

Excelente producto, justo lo que quería, buena potencia, la batería le dura mucho y eso me da la oportunidad de un uso más prolongado

Muy práctica, excelente para uso en areas estrechas de difícil acceso y mejor que cuente con batería extra
