Abstract
A portable torque power tool is disclosed herein and includes: a motor to generate a turning force; a drive to transfer the turning force; a turning force multiplication mechanism assembly to multiply the turning force; a shifter assembly to shift the tool between a lower speed/higher torque (LSHT) mode and a higher speed/lower torque (HSLT) mode; a torque transducer to measure torque output from a portion of the turning force multiplication mechanism assembly; wherein torque output is controlled by the torque transducer in LSHT mode; and wherein torque output is controlled by motor current in HSLT mode.
