Abstract
A bit-removal assembly includes a first ring coupled to an output shaft for co-rotation therewith, a second ring supported on the lower retaining ring of the output shaft, a frusto-conical surface on at least one of the first or second rings, and a wedge positioned between the first and second rings and engaging with the frusto-conical surface. A collar defines a cam surface located radially outward of the wedge. The collar is movable between a locked position, in which the cam surface is engaged with the wedge to displace the wedge radially inward on the frusto-conical surface to separate the second ring from the first ring, and a released position, in which the cam surface is misaligned with the wedge to permit the wedge to move radially outward on the frusto-conical surface. A biasing member urges the collar towards the locked position.
