Product Review
Product Description
Most manufacturers seem to be using lithium-ion battery technology to create lighter versions of existing cordless tools, or high-voltage tools that would have been too heavy for use with older battery technologies. Bosch however, seems to have also used the opportunities presented by lithium ion to dream up tools that have never even existed. Last year, they scored big hits with the PS-20 Pocket Driver and I-driver, which redefined ideas about drills and screwdrivers at the same time.
This year, they've extended that out-of-the-box thinking to impact drivers, with the Litheon "Impactor", and it is another jaw-dropper.
Impact drivers are smaller and lighter than cordless drills, but because they have a simple hammering function and are geared specifically to spin fast, they produce about three times the torque of a drill. This means an impact driver will put in screws, bolts, and other fasteners much faster than a drill would (especially in sheet metal). They can drill holes, too. What they won't do is drill holes bigger than 1/2 inch, but they'll handle just about any job a homeowner or contractor would do around the house.
In size and feel, the Impactor is very much like the Pocket Driver. It's small and light enough to fit into a drawer. Hitched to your belt, you could carry it around all day and barely notice the weight, although it looks so cool, you're definitely going to want to keep taking it out. With the three LED lights on the front, Bosch has not only made sure this thing doubles practically as a spare flashlight, they've really solidified the space-age ray gun look, making the Impactor pretty hard not to pull it out just to play with. With the hammer action on top of the respectable 10.8 volts of power however, this can do even more than the Pocket Driver could. We used it to drive screws through sheet metal and 3/8-inch bolts into pine. It wasn't as fast as 14.4- or 18-volt models, but it got the job done well enough to make this a truly all-purpose tool
The lithium ion batteries also have the advantage of staying charged when they are not used, which makes them great for tools that get left in drawers for long periods of time between uses. --Tod Harrick

About Bosch Litheon
Bosch continues to push the boundaries of cordless at both ends of the voltage spectrum with Litheon, the industrys most advanced lithium-ion battery technology, professionals will continue to benefit from innovative, powerful, long-lasting and comfortable tools, such as the new 10.8-volt Impactor.
About the PS40-2 Impactor
The innovative new ultra-compact 10.8-volt Litheon Impactor Fastening Driver (PS40-2) is the worlds smallest and most lightweight impact driver. It delivers 60% more torque than an 18-volt drill/driver, but at 6-inches tall by 6-1/2-inches long and 2.2 lbs, it is less than half the size of an 18-volt NiCad impact driver. A high-performance Bosch motor and all-metal gears produce 1,800 RPM and 3,000 BPM and turn the powerful hammer and anvil system to deliver 800 in-lbs. of torque. For a full range of professional fastening applications, including self-tapping screws, nuts and bolts, lag bolts up to 5/16-inches and more, the PS40-2 is sized to fit in any tool belt pouch or pocket and be productive all day long.
Loaded with Features
A bright 3-LED work light specially positioned in the nose of the tool effectively illuminates any work area. A hex quick-change chuck allows for instant changes from drill to driver bits. A sensitive variable speed trigger offers optimal control over speed for varying applications, while the tools superior ergonomic design, which includes soft-grip, adds to user comfort over long periods of time.

Owner Reviews, Ratings, Comments and Criticism
I've had the PS40 for over six months now and find it to be an excellent driver - nearly perfect. At first I was put off by the noise of the impact mechanism, but after drilling hundreds of deck screws I came to appreciate the tremendous amount of torque available. More torque is usually a good thing, but in a standard drill/driver excessive torque can be bad as it requires more work, is less precise, or possibly dangerous if the tool, say, twists you off a ladder. The PS40 doesn't have this problem, in fact, it requires less effort to drive the same fastener as a standard driver or drill. I found myself backing off on the downward pressure to the fastener - much less force is necessary to keep the bit engaged. In particular this is a boon for those situations where you can't get a good and strong angle, such as working overhead or where the screw is hidden from view. With the PS40, if you can get the bit in the fastener that's probably enough to get the job done. The impact noise is loud but not "hurt your ears" loud. If you're using it inside it may annoy others in the house, be forewarned. The size, grip, weight, balance, and battery life are all excellent. It really does feel like a phaser, that is, if the phaser actually existed. I have not tried using it as a drill. To do that would require purchase of a conversion chuck such as the DEWALT DW0521 Quick Connect Impact Driver Conversion Chuck (which is now on my wish list), or hex-shanked drill bits. Still, I find it quicker to use a regular drill for holes and then swap to the driver. For lighter duty driver applications, I would think the non-impact PS20 would be ideal (though I've not tried it). Given that the '20 retails for just over $100 (for the 2 battery & charger kit) I'm considering buying one to compliment the 40. If they ever sell just the PS20 driver alone I will definitely buy one. The PS40-2A kit differs from the PS40-2 in that they throw in a belt holster. I wouldn't pay extra for it. I strongly recommended the PS40 for mid to high torque applications, such as deck building, drywall hanging, and framing.
