Abstract: A hand-held power tool is provided that includes a housing assembly, an output spindle, and a motor endbell. The housing assembly supports an electric motor having a rotor configured to rotate when the electric motor is supplied with power. The output spindle protrudes from an output end of the housing assembly, and is functionally coupled to the rotor such that the output spindle rotates in response to a rotation of the rotor. The motor endbell is located on the housing assembly adjacent the electric motor and opposite the output spindle. An illustrative controller is operable to determine phases of a fastening operation in which the hand-held power tool is operating. The phases of the fastening operation of the hand-held power tool include two phases including: (1) a continuous run phase and (2) an impacting phase.
