- The DeWALT, RIDGID impact driver, or any other model brings convenience when screws tightening. Due to a low level of resistance, the tool is able to operate in a shockless mode, developing the continuous force necessary for twisting. If the resistance increases, the tool switches to shock mode when tightening is performed with a high moment. - The tool eliminates the reliance on large pressing forces, which allows you to save the surface of the screw hats from damaging. This feature of the tool makes it possible to unscrew the screws, the head of which has already begun to tear out. - It helps reduce torque load on the user's wrist.
