A power tool (10) for driving fasteners (12), in particular a clip applicator tool, is provided is that includes rear housing and forward head portions (24) with a piston (20) in the rear housing and a fastener driver (18) in the head portion. The rear housing preferably includes a cap member (44) and a housing member (32) with movement of a fluid admission valve (42) split between both to keep size of the cap member to a minimum. Further, guide surfaces for the fluid admission valve member can be integrated into the cap and housing members to avoid having a separate valve body therefor. The forward head portion has light weight outer walls and at least one high strength bearing insert (114) for taking the high loads generated by the tool drive assembly including the driver thereof. In one preferred form, the tool employs both the above-described rear cylinder and forward head portions to provide a balanced, light weight hand-held tool that is ergonomical to use. |
