This makes the tool easy to use and ideal for applications in confined spaces. The wh36dc is the highest performance in the industry. It provides the highest operating parameters throughout the battery discharge cycle. The 36v lithium-ion battery voltage means full performance is maintained for longer even when the battery is running low and slows down the motor temperature rise. The screwdriving speed of this tool is approximately 5% faster than its predecessor.thanks to the brushless motor with a very high torque (215 nm) and the triple hammer impact system (a hammer with three lugs reduces vibrations by performing 3 blows per revolution instead of the conventional 2) the device provides greater comfort and less backlash (slippage of the bit from the screw head) which is perfect for even in light applications such as short or thin screws. Additionally to adapt to various applications a 4-stage screwdriving mode selection function is also included.the device is equipped with a durable lightweight and handy aluminum housing with ip56 technology four operating programs a perfectly profiled handle made with soft touch technology a post-type switch for precise and quick change of rotation direction a battery charge level indicator an electric brake a hook-shaped latch and a workspace lighting (led).thanks to multi volt 36v technology the screwdriver can continuously drive long large-diameter screws twice as long as its 18v counterpart.**
