Impact Driver Kit: 1,859 ft-lb Max. Torque, 1,500 RPM Free Speed, 3,000 Impacts per Minute, 18 V

These cordless impact drivers run on Fein batteries and use impact force to increase torque when making holes and driving fasteners. The batteries can also power other Fein tools of a compatible series and matching voltage. Tools using lower-voltage batteries are generally lighter and more compact but less powerful than tools using higher-voltage batteries. Tools using lower-capacity (Ah) batteries are less bulky but store less power than tools using higher-capacity batteries.
