The IDH182 impact driver features the Bosch Performance Control System, which allow users to adjust tool speed and torque with a push of a button to match the tool's performance to the application at hand. This feature helps tradesmen across the board eliminate screw cam-out in screwdriver mode and screw shearing in the self-tapping screw mode while generating max output in general purpose mode. An EC brushless motor provides 2X motor life, increased performance and improved runtime.
