The Bosch PS42 is the first EC brushless impact driver from Bosch in the 12V class. The EC brushless motor provides improved motor efficiency, which results in longer runtime, a more compact size, and lighter weight. The EC brushless motor also provides 2x the life of the previous generation due to less heat generated and fewer components that can wear down. The PS42 also sports the Bosch Performance Control System, which allows you more control by adjusting your maximum speed and torque. An included belt clip provides quick and easy storage, while the 3 ring LED light illuminates even the darkest work spaces.
