  • Tool bit or tool holder for power tool
    Patent number: 8641536
    Abstract: A tool holder for use with a power tool includes an input shaft with a rear portion couplable to a power tool, and an output shaft with a front portion couplable to a tool bit. A clutch assembly releasably non-rotationally couples a front portion of the input shaft to a rear portion of the output shaft, and includes a recess in the front portion of the input shaft or the rear portion of the output shaft, an aperture in the other of the front portion of the input shaft or the rear portion of the output shaft, a roller received in the aperture, and a spring that biases the roller radially inwardly toward the recess. The spring enables release of the roller radially outwardly from the recess when a predetermined torque threshold is exceeded, such that torque is not transmitted from the input shaft to the output shaft.
