12-Volt Litheon Batteries for Long-Lasting Power
The PS40-2A gets its power from Litheon batteries, the most advanced lithium-ion batteries available today. These batteries allow more battery charges and provide longer runtime with no memory effect--meaning the batteries don't need to be empty before charging. The batteries can also be taken out of the charger before charging is complete.

Other benefits include: significantly less self discharge; electronic cell protection that guards against overheating, overload, and deep discharge; and no loss of power from the first to last screw or hole. Best of all, these batteries will fully charge in 30 minutes and will be at 85% capacity in just 15 minutes.

Compact, Lightweight Design for Efficient, Fatigue-Free Work
The PS40-2A features an innovative driver designed with a compact and light housing and superior performance. Measuring only 6.5 inches in length and weighing just 2.2 pounds, it performs up to 80% of all impact-driver applications. And because it easily drives screws without the need for pushing, the tool will help prevent you from becoming overly tired on the job.

Built for a Wide Range of Heavy-Duty, Professional Applications
Ideal for driving and tightening metal bolts, screwing wood up to three inches thick, drilling wood up to 3/8 inch thick, and drilling sheet metal with a maximum thickness of 5/16 inch, the PS40-2A offers impressive range. You can drive fasteners into wood and concrete and enjoy the anti-shock protection provided by the Heat Shield. With this handy tool you can also drive fasteners into sheet metal, tighten nuts and bolts, complete a range of automotive repair jobs, install a garage door, build a deck, tackle plumbing issues, complete interior and exterior steel framing jobs, and much more.

Hammer-and-Anvil System for 800 In./Lbs. of Torque
The PS40-2A comes equipped with a Bosch-designed hammer-and-anvil system, which produces double the torque of a gear-driven system. The PS40-2A provides a truly impressive 800 in./lbs. torque--up to 300% more than other drills/drivers--giving you the necessary power to drive or remove lag screws. At the same time, the innovative design of this mechanism ensures that torque is not transferred to your hand, resulting in improved control and a lower risk of wrist injury, even during your toughest jobs.

Up to 3,000 BPM for Quick Fastening
The PS40-2A also delivers 1,800 RPM/3,000 BPM, so you can power through drilling and fastening jobs both big and small. And you can enjoy all this power without having to carry around a big, bulky tool. Thanks to its two-layer planetary gear, the tool's diameter shrinks to a truly compact size.

Sealed Internal Components Prevent Oil Leakage
To help keep operation smooth and trouble-free, the gearbox's internal components are sealed by aluminum housing and plastic rear housing to prevent oil leakage. This design also maintains optimum lubrication for longer life. For peace of mind, a rubber shock absorber behind the impact mechanism helps minimize vibrations and increases the stability of the gearbox if it's dropped, even from 6.5-feet.

Smart Features for Easy Operation
A unique LED Light Ring with three lights provides ample illumination in tight or enclosed spaces. The LED also offers a pre-light to brighten your workspace when you pull the trigger. Additionally, anti-slip rubber bumpers on the tool body prevent slipping and damage.

Finally, a forward/reverse switch is conveniently placed for both right- and left-handed users and is accessible by even petite hands.

ProVantage Guarantee
The PS40-2A comes with the ProVantage three-year protection plan, which guarantees two years of battery protection and one year of tool protection. Under this plan, you can receive two years of free battery replacements, tool replacement for one year, and a free tool repair package for the second and third years.

5.0 out of 5 stars This tool rocks!, March 15, 2009

This review is from: Bosch PS40-2A 12-Volt Max Lithium-Ion Impact Driver (Tools & Home Improvement)

Within 10 minutes this awesome little tool became my absolute favorite item in the shop. I do a lot of quick and dirty assembly of things out of 2x4s and 3" drywall screws. Before I had this driver, I used a drill to drive those screws. Every time I did, by the time I was done my wrist would be killing me. Why? Because to drive a long phillips head screw through 2 2x4s you have to push really hard on the drill to keep it engaged with the head of the screw. And even then, it would often strip the screw head and/or fail to sink the screw all the way.

Now enter the ps40-2a. With this thing I can drive 3" drywall screws all day long, and I can hold the tool with two fingertips when I do it. I'm not kidding. 2 fingertips and no pressure is all that's required to hold this tool in place while it pounds your screws through the wood effortlessly.

It surprised me at first that this thing is slower than a drill. It is also quite loud when the hammer action engages (I use ear protection with it). But neither of those things is enough to dampen my 5 star rating. If you ever have to drive long screws into wood and know what I'm talking about with hurt wrists from pushing on your regular drill, then order this thing today. You'll be so glad you did.

5.0 out of 5 stars jammin'!!, November 3, 2008

This review is from: Bosch PS40-2A 12-Volt Max Lithium-Ion Impact Driver (Tools & Home Improvement)

This is the smallest & yet the most powerful driver I've ever used. It jams 'em right in.

I'm just a DIYer but some recent big projects needed lots of screwing into 2x4s. Floor fixes & bathtub support replacement! Bang! Bang! Bang! When that impacter hits - it's noisy! And the screws go in FAST! Interestingly they come OUT even faster, shockingly fast, like a 2 1/2 inch screw comes out in a second. Cool!

THIS is the tool they warn you about with the "torque settings" (which I never had a problem with set on MAX) adjustments on other tools. A light touch does most jobs fine. It will drive screws THROUGH whatever, and thin soft wood cracks & splinters like candy! Oopsy!

Pro's may want to go with the Makita BTD142HW 18V for a job site, but this is 2/3 the strength (more that enough), 2/3 the weight, and can be found for 2/3 the price(or less). Nicely rounded out specs.

3.0 out of 5 stars Nice, but makes a lot of noise to make up for its lack of speed and power, June 25, 2009

This review is from: Bosch PS40-2A 12-Volt Max Lithium-Ion Impact Driver (Tools & Home Improvement)

I bought this for work, not just light weekend duty. I'm a bit disappointed with its lack of speed, power, and the amount of noise it makes. It has so little power that you can grip a normal bit driver chuck in your hand and it will begin to ratchet the impact drive. It won't drive a 3" screw fully into pressure treated framing lumber, at least not within a time span I was willing to wait. Plus, it's not much lighter than a normal lithium ion makita 18v or panasonic 14.4v impact driver. With either of those a 3" screw can usually be driven ~3/4 of the way in before it even starts to impact drive, and at probably twice the speed.

Another annoyance is the trigger, which binds up a bit if your finger is not square to it and if you don't put pressure on it perfectly straight back. If your finger is just on the lower edge the trigger will twist a bit and bind up, not wanting to push in. This is particularly annoying when driving screws above your head or any odd angle where you're not easily able to hold the driver with your hand/arm straight back. Also, the trigger/driver is not as sensitive as some other drivers I've used, especially panasonic's. The trigger lightly depressed will turn on the LED lighting, but there's no super slow speed which makes rotating your screwdriver bit to line up with a screw (especially slotted screws) a real pain.

Not to say this is a bad product, as overall it's a nice little set. The size is nice and the battery life is pretty good and fast charging, plus the soft carrying case is small and handy. It's also about half the cost as other drivers I've used. I just wish there had been a review where someone had compared this driver to a more serious product.
