Abstract
A power tool includes a drive mechanism, a housing enclosing at least a portion of the drive mechanism, a spindle rotatable in response to receiving torque from the drive mechanism, a first drive element coupled for co-rotation with the spindle, the first drive element including a first sliding contact surface, and a second drive element rotationally fixed to the housing, the second drive element including a second sliding contact surface engageable with the first sliding contact surface while the spindle rotates. At least one of the first drive element or the second drive element includes an amorphous metal material.
