A tool for interchangeable tool attachments, the tool comprising: a tool shaft having a tool attachment end for receiving the tool attachment; a sleeve movable with respect to the tool shaft between a tool attachment lock position and a tool attachment release position, wherein in the tool attachment lock position, the sleeve is moved in a direction opposite the tool attachment end, and wherein in the tool attachment release position the sleeve is moved in a direction toward the tool attachment end, the sleeve having a rearward edge and an outer periphery greater than an outer periphery of the tool shaft; a collar having a forward end and an outer peripheral portion at least about as great as the sleeve outer periphery, the collar disposed rearward of the movable sleeve wherein the collar forward end is in close proximity to the sleeve rearward end when in the tool attachment lock position so as to deflect objects away from the rearward edge of the sleeve when in the tool attachment lock position thereby preventing inadvertent release of the tool attachment during use.
