Several years back a funny little 10.8v cordless drill hit the market from Bosch and at first people were not sure what to make or it (see our 2007 post Ain’t No Kids Toys). Fast forward to 2010 and the compact cordless tool category has exploded with tons of exciting new tools in the 10-12 volt range for home owners and professionals alike.
The new PS21-2A ($129, Ohio Power Tool) is the 3rd version of the Bosch Pocket Driver and is available now, along with the 3/8” chuck drill/driver PS31-2A ($143, Ohio Power Tool). These next generation tools are built solid and no longer looked at as the “small tool” additions to the arsenal but more as replacements for some tried and true 14.4v and 18v tools. Both of these tools have plenty of torque to hang cabinets or even help build the occasional deck. At the same time the light weight design and 20+ clutch settings make it a nice tool for delicate jobs like working on computer boxes or assembling different items which can definitely be awkward with an 18v drill.
Testing the PS21-2A
When I pulled the PS21-2A out of the box the first reaction was honesty, did they really need to redesign the whole tool just to shave an inch or so off the nose. It turns out the smaller compact design is just a nice bonus but the real reason it got an overhaul is the guts. The new Pocket Driver has 265 in lbs of torque where the first generation had 80; it also now has 2 speeds like a real driver should. This new generation also gets new batteries which “pack a little more punch” (BAT412 instead of BAT411) but either battery works on new or older tools. See this photo album for 20+ pictures from the test.
To test out the tool, that was provided for us, we simply stacked (3) 2”x4” and started screwing them together. First drove 10 large exterior 3.5” screws, then 50 standard 3” screws, then another 30 2” square drive (used the Bosch P2R2 bit which works splendidly with both square & phillips). After 90 screws the entire board was full and still plenty or juice left so to really test the torque and clutch went back over all 90 screws to see how far into the wood the screws could be driven. Basically hitting max torque 90 times in a few minutes, at which point you might expect some overheating but was not a problem for this tiny tool even with my other hand basically covering the entire tool. It finished that task and still had a little juice left but was pretty much fading out. With a few breaks to snaps pictures and find some more loose nails it took about 30 minutes to kill the battery at which point the 2nd battery was fully charged ready to roll again. I am pretty confident in most real life situations the battery would be good for an hour or more of constant use and easily last all day with occasional use.
It is safe to say the new PS21-2A blows away the competition in the 12V compact driver category. However the short fall with the Bosch 12V Max line of tools does not come from any one of their tools but more with the depth of the line. With a head start as the creators of the category you would expect they would have the most tools in their lineup but that is definitely not the case. The Milwaukee M12 line for instance now sports over 20+ tools, many specific to professionals but lots of versatility throughout the line. If that is not a concern in your world and you are just looking for the best possible driver or 3/8” drill, Bosch may very well be your choice.
