Product Overview


The Bosch PS21-2A 12V Max Two-Speed Pocket Driver Kit features a driver that provides a compact design with outstanding power. It has a short head-length and height, and it weighs 1.8 Lbs., but it is rated at 265 In.-Lbs. of screw-driving torque. Able to manage many of the fastening tasks on a worksite, this tool can be a carry-along tool for installers, contractors or anyone who handles a lot of driving work in difficult situations. The kit includes two 12V Max batteries and a 12V Max charger.
Variable Speed - The PS21 features two speeds (0-350 rpm for high torque and 0-1,300 rpm for high speed) and 20+1 clutch settings. This allows for precise adjustments to furnish accurate driving and fewer stripped screws. The beefy performance of high torque and the convenience of two speed settings allow the driver to tackle all but the toughest applications on a jobsite. It has a variable-speed trigger for reliable speed regulation and additional user control.
Compact Driver - With a 5.6 In. head-length, this driver is able to fit into very tight areas and still drive the screw head-on. Its compact size combined with its 1.8 Lbs. weight makes it an ideal tool to pack when going to jobs that will be in tight quarters, and it's great for continuous overhead work. This tool in fact is one of the lightest 12V drivers on the market.
  • This next generation driver also packs 265 in-lbs. of torque - Up to 2x more torque than the competition.
  • Compact and Lightweight - Shortest height and head length along with lightest weight make this tool great for overhead/tight area work
  • 2 Speeds (1st - 0 - 350 RPM / 2nd - 0 - 1,300 RPM) - Up to 2X Faster driving and drilling than competition
  • Universal Bit Holder - Only universal bit holder in its class which clamps on all common bits (C6+E6)
  • 20+1 Clutch Settings - Perfect torque adjustments for precise screw driving
  • Built in LED light for minimal lighting and tight spaces
  • 12V Max Cordless Lithium-Ion Pocket Driver - PS21-2A
  • (2) 12V Max Lithium-Ion Batteries - BAT411A

Drill Thrill!
As a DIY guy, this drill has really met my needs and expectations in a variety of home projects. I was able to quickly take care of a number of projects that my girlfriend had been wishing for; a shelf here and there, a new door mirror, a three-shelf wire rack for the laundry room and the transformation of a nice, but useless wooden plaque into a key-hanger for the entryway. I can't wait for the next projects, whatever they may be...

My only suggestion for Bosch would be that they clearly list or recommend the type of bits that should be purchased for this drill. I ended up having to buy two different Bosch bit sets before I ended up with the correct assortment of hex shank drill bits and power screwdriver bits. I ended up preferring the Bosch CC2130 Clic-Change 27-Piece Drilling and Driving Set with Clic-Change Chuck, even though I didn't need the Clic-Change Chuck since it is built-into the PS21-2A drill.

Whatever the case, its a great drill and I'm glad that I put my faith in Bosch.I expect that this slightly more expensive drill will last me for many many years.

Versatile and Compact
I bought this to use in the engine oil-change lane at an automotive service department. The tool performed great at any task the tool was used for. Never had any technical or charging issues for the short time that the tool was employed.. Certain tasks in automotive require the tool to be powerful, and certain jobs require the tool to be delicate. This tool can adjust between torque settings– torque setting 1 or setting 2 –and there are settings for the power (a low of 1 and a high indicated by a drill symbol. The trigger-activated guide light could be helpful in dark areas when trying to locate the head of a bolt or screw. This tool can be brought home and used for tasks around the home.

Great tool.
Excellent speed control combined with lots of torque makes this one of the best power screwdrivers I've ever used.

My only minor complaint is the battery life could be better. Not a big issue and the fast 30 minute charger makes up for this limitation.

Bought this to make an electric scooter
I bought this to mount on a Razer kick scooter. This unit has the ability to move about 130-200 lbs of human weight.

My project required I disassemble the unit, chop off the handle and shorten the 1/4" chuck with a dremel.

This driver unit was perfect for my project!

Awesome tool
Excellent cordless driver: compact yet robust, nice grip, nice torque. The variable speed depending on the trigger pressure is very useful. The Li-ion type of battery is a must.

Daily use in a mechanic shop
I use this daily in a GM dealership. Sometimes abusing it and it holds up very well. Have had it for 1 1/2 years now. I like the varible clutch that I can turn down for smaller screws or turn up for the heavier stuff. Occasionaly I have a problem with the light staying on in which case I unplug the battery and reinsert it. It took me awhile to get use to the slow trigger, when I first push the trigger it takes about 1/2 a second for it to start turning, but I suspect it has to do with the circutry checking the battery voltage.

I bought mine about three months ago and use it daily as an automotive technician. The battery does not need to be charged constantly, its lightweight and reliable. I recommend it!
