With the YOUWE 12V cordless impact driver you can easily screw small and large screws. It has a compact and light weighted design, which makes it the perfect tool for screwing and unscrewing in hard to reach places. With the use of an impact driver, you do not need any strength to screw long and large screws in different materials. The technology, which is used in an impact driver, allows you to screw long and large screws with a high torque, without using any strength and with a low kick-back. The low kick-back prevents the impact driver from spinning in a certain direction. You can also always see where you are screwing, thanks to the LED working light.
