Abstract: A rotary impact tool includes a housing, an electric motor, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece of at least 900 ft-lbs of fastening torque. An anvil has a bore defining a hexagonal cross-sectional shape and having a nominal width of 7/16 inches. A hammer is rotationally and axially movable relative to the anvil for imparting the consecutive rotational impacts upon the anvil. A spring biases the hammer in an axial direction toward the anvil. A battery pack has a nominal voltage of at least 18 Volts and a nominal capacity of at least 5 Ah. The rotary impact tool has an overall weight including the battery pack that is less than or equal to 7.5 pounds. A ratio of the fastening torque to the overall weight is greater than or equal to 120 ft-lbs per pound.

Abstract: System for cooling a power tool. One exemplary power tool includes a housing including an air intake and an air exhaust. The power tool further includes a motor and a fan configured to pull cooling air into the housing through the air intake, and exhaust the cooling air out of the housing through the air exhaust. The power tool further includes a plurality of field-effect transistors (FETs). The FETs couple the stator coils to a power source. The power tool further includes a FET board within the housing. The power tool further includes a heat sink within the housing. The heat sink includes a first mounting portion and a second mounting portion. Each of the mounting portions includes a horizontal fin extending toward a respective side of the housing. A plurality of vertical fins extends from a top surface of each of the horizontal fins.
