About the Product

The Bosch PS41 12V Max Impact Driver is the most compact driver in its class, with a 5.4 In. head length. Yet it delivers a max torque of 930 In.-Lbs., thanks to Bosch's hammer-and-anvil system. It weighs just over 2 Lbs., but it can produce a no-load bpm of 0-3,100 and a max 2.600 rpm. The driver was designed with a spring-loaded impact mechanism that reduces user fatigue. This makes this driver excellent for overhead installations and tasks where room is very tight. It also has an impressive runtime provided by the Lightweight 12V Max Power System. This driver includes a three-light LED Light Ring, a battery gauge indicator and a 1/4 In. hex drive with quick release.

The Bosch PS42-02 12V Max EC Brushless Impact Driver Kit features a very compact but powerful 1/4 In. hex driver, two 12V Max 2.0 Ah batteries and a charger. The PS42 driver has a 5.5 In. head-length and weighs just 1.6 Lbs., but it is a powerhouse, with an optimized impact system. It also has the Bosch performance control system, which supplies two speed settings, one for high speed and high torque and one for low speed and low torque. This delivers no-load rpm ratings of 0-1,200 and 0-2,600 and no-load impact-per-minute ratings of 0-2,700 and 0-3,100. The drivers produces 975 In.-Lbs. of max torque, great for repetitive driving tasks and about 85 percent of the fastening tasks around the professional jobsite. The tool's EC Brushless motor and improved all-metal gearbox allows for unmatched efficiency, great runtime and longer life. This driver has a 1/4 In. hex drive and a three-LED light ring.

Bosch PS41-2A 12-Volt Max Lithium-Ion 1/4-Inch Hex

What a major improvement in speed and torque! I bought another to have on hand for helpers.
I bought this tool in the combo kit with the PS-21. I do use the PS-21 more often, but when I need to drive long screws or into tough material I use the PS-41 because the impact function takes all the torque off of me and keeps the bit in the screw head so that they don't strip out.
Decent torque, fast charging, great size-weight ratio, and a center of mass close to the hand to reduce fatigue.
A lot of torque and it is so small it can almost fit in your pocket. 12 Volt... so what? It is the performance that counts.
Love this thing. the torque on it is amazing allowing me to unscrew set screws that just won't budge any other way.

Bosch PS42-02 12V Max EC Brushless Impact Driver

I got this month ago this little guy has enough power to do lot around the job site puts 4 inch screws without problem. Ec brushless motor will outlast any other impactor on the market.
The torque is so much, that there are 2 settings - with high and low option.
I love the power and speed of this thing as well as the battery meter and the adjustable clutch which will suddenly turn into an Impact drill.
I liked the fact that it was a brushless unit. I also like that you can change it from low torque to high torque with the push of a button.
The torque is so much, that there are 2 settings - with high and low option.

What customers say about "Features"

Bosch PS41-2A 12-Volt Max Lithium-Ion 1/4-Inch Hex

The PS41-2A is a great improvement on an already great tool. Brighter LED lights, a built in battery meter, a longer running battery, more torque, more speed, all inside an even smaller casing to get in those tight spaces.
This is one of the lightest yet most powerful impact drivers you will find. Fits into tight spots where the LED light really comes in handy. The battery level indicator is really nace as well.
I received a 12v cordless impact driver this past Xmas, it is unbelievable! I work in the maintenance field and it is so versatile. It can do most jobs that a larger drill, but it is compact and very ergonomic.
My favorite features are relatively high torque, battery meter, and overall ergonomics. Automatic impact "kick-in" is also nice!
Unit is durable and the battery life is exceptional.
My only complaint is the trigger. When you first pull it there is a slight hesitation before it reacts.

Bosch PS42-02 12V Max EC Brushless Impact Driver

Battery life is amazing and it’s powerful enough for what I use it for. Compact and comfortable.
The light is bright, and can be controlled with a button. There is a battery charge indicator.
I prefer the compact size of the 12v over the larger varieties. It allows you to get into tighter spots and use the driver longer with less fatigue.
Well balance prefect grip for allday long holding. Lights on the impactor makes you see the work piece.
Battery last very long it's small and ergonomic little tool every dyi guy should have it at the arsenal. Will replace your current impactors.
