Abstract
A rotary tool mandrel includes a shaft, locking projections, a collar, and a fastener. The shaft extends along a longitudinal axis and includes a distal end. The locking projections protrude radially relative to the longitudinal axis and positioned on opposite sides of the longitudinal axis from one another. Each of the locking projections define a locking projection outer profile that is rectilinear. The collar is coupled to the shaft and includes a pair of coupling projections protruding from a surface of the collar adjacent the distal end of the shaft. The coupling projections are angularly offset from the locking projections with respect to the longitudinal axis. Each of the coupling projections define a coupling projection that is rectilinear. The fastener is coupled to the shaft and movable relative to the shaft along the longitudinal axis, and movement of the fastener causes the locking projections to move toward the coupling projections.
