Abstract
A power tool having a plastics material housing and a power output spindle is provided with a tube-like metal member in the front end of the housing. A bearing is received within the tube-like member for supporting the spindle. The tube-like member has at the front end thereof radially outwardly extending tabs for dissipating heat therefrom. The tabs are preferably partially embedded in the plastics material of the front end of the housing for anchoring the member therein, alternate tabs preferably being angled rearwardly. The member may also support ratchet teeth of a hammer drill. A fan may be mounted on the spindle in the region of the front end of the member for facilitating dissipation of heat from the radial tabs.
