Bosch PS21 Pocket Driver - Review
When we first heard that Bosch was releasing another 12-volt driver, we sort of drifted off to sleep. We dreamed of a world where tool companies stopped releasing like-tool after like-tool with only minimal upgrades between versions. Then we actually saw the new tool and became convinced that this time the guys at Bosch had really gone around the bend to la-la land. There's no way around the fact that the tool looks pretty silly at first glance (it's the stubby nose that takes the cake). Thankfully though, Bosch sent us one to try out and boy did that put an end to our snooty little preconceived notions.
Our constant caveat with 12-volt drivers is that they're good, but we always want them to be more powerful. We've never understood how 14.4 drills feel closer in power to 18-volt drills than 12-volt drills feel to 14-volt drills. Still, they're handy, so we usually keep a 12-volt on us at all times, for those hard to reach areas or for light duty punch work tasks.
But back to the Bosch PS21. First off, the power out of this little tool is incredible. Not to mention that it's smaller than the competition. We were stunned when it had no problem sinking a 6" Timberlok screw into a 2x6. We tried out a few of the other 12-volt drivers we have around (including the older Bosch PS20) and the results were pathetic in comparison, they could hardly even sink the screw half way. We then used the PS21 as our primary tool building a workbench and it had no problem dealing with 3" screws. Sure, it's not as fast at a 14.4-volt, but it's getting there.
The reason for this is that Bosch has rebuilt the tool from the ground up and this new design gives you 265-in-lbs of torque, more than double that of the older PS20. The new tools also has an LED, a 2-speed drive train and a 21 position clutch. It sits very comfortably in the hand and it's only just over 5-1/2" in length.
The bottom line here is that this tool is a real triumph. Not only is it small but it reaches a level of power that we had given up on as far as 12-volt drivers are concerned. It's a giant step in the right direction for Bosch and their 12-volt line. But now, they need to follow it up and start expanding the available tools. The 12-volt drill we tend to carry around is the Milwaukee because in one bag (with one charger), we have our driver, a flashlight, a right angle drill, the Hackzall, the power port and a stereo. It's a tough sell to ask us to add another bag and battery charger to our already crammed truck box. We'll do it for this tool, because it's so impressive, but it would be nice to be able to throw a few other items in the Bosch bag.
The PS21 sells for anything from $130 (Ohio Power Tool) to $145 (Amazon).
