A portable power tool including a power unit housing having first and second housing segments joined together in clam shell fashion includes a tool head which is mounted to extend forwardly from the power unit housing by means of a bearing plate provided with tapped holes for reception of screws extending through the tool head. The bearing plate is contained entirely within the interior of the power unit housing to avoid external seams by means of a clamping flange defining the forwardmost extent of the first and second housing segments. The bearing plate is formed with plural auxiliary handle mounts projecting from openings formed in the first and second housing segments for reception of auxiliary handles. The mounts are adjacent vents in the housing segments promoting cooling of the bearings during operation. |
