ABSTRACT:
A quick-release mounting for a cutting wheel comprises a housing adjustably mounted in an arm, and a hollow shaft rotatably supported in the housing. The shaft has an expandable collet hub on which a wheel can be received. A mandrel extends within the shaft and has a tapered part to expand the collet hub; the mandrel is spring loaded toward expanding the hub, and a handle on the mandrel allows thrusting the mandrel in opposition to the spring load for release of a wheel. Locking members guard against accidental release of a wheel from the shaft, and an adjustable stop prevents over-tightening the collet hub. Adjustments of the mounting to mount or dismount a wheel and to change position thereof can all be accomplished without need for tools.
