Bosch PS31-2A 3/8" 12-Volt Drill/Driver - Review
A little while back, we cobbled together a glowing review of the new Bosch pocket driver, the PS21-2A. It's a little monster of a tool and we found it could basically replace our 14.4 drill and could even handle some things reserved for the 18-volt (although not on a day in and day out basis). Well, soon after releasing that little fella, Bosch hit the stands with the PS31-2A, which is basically the same tool, but with a 3/8" three-jawed chuck. They dropped one in the mail for us, and for the last month or so, we've used it extensively, both on the job site and in the shop.
And there's really not a whole lot to say other than that it has quickly achieved the spot of our primary drill/driver. Everything we liked about the PS21 is there but now we have the added functionality of the three-jawed chuck. Because of the chuck, the PS31 is a longer tool than its driver counterpart, but we'll take that extra bit of length any day in order to get the added versatility. Sure, we know that you can buy bits with the 1/4" hex end, but that's honestly a pain in the ass and we don't want to have to go out and get a special set of bits just for one tool. Not to mention, the three-jawed chuck lets us use countersinks, centering bits and all kinds of oddballs that we couldn't use with the PS21. To put it simply, this is a fully-functional drill.
Out of all the 12-volt drills and drill/drivers that we've seen and been able to really field test, this one is the best and it's all in the power. Sure the other features are there, the battery gauge (a very nice feature on li-ion tools), the LED, and the case with all the extra room for bits, but a drill needs to be powerful first and foremost, and this one certainly is. The PS31 had no problem passing the TimberLok test, sinking a 6" screw into a block o' PT. It was a strain on the tool, but not that much of a strain. In addition to this, the PS31-2A just performed well everyday. 1-5/8" screws, no problem, 3" screws, not a problem (but a whisker too slow for production work).
So if you're a handyman who does a lot of punch list work, or maybe someone who doesn't want to lug around a massive 18-volt drill all the time, or a homewoner who wants something small, reliable and powerful, it would be smart to seriously consider this tool.
As far as price goes, the PS31-2A is about $150, making it one of the more (if not the most) expensive 12-volt drill/driver on the market and putting it $20 above the PS21-2a. For the added ability and raw power, we think it's worth the investment.
