Handle grip for a power tool

A profiler particularly adapted for finishing the surfaces and contours of dies and molds. The profiler employs a cam assembly which converts rotary input motion to reciprocating output motion for operating a reciprocating member having a suitable tool attached thereto. The profiler is designed to generate substantially lower temperatures within the bearings supporting the cam assembly, and the bearings themselves are particularly designed to be easily replaceable in a sleeve which, with the bearings, form a bearing cartridge. The use of the bearing cartridge eliminates the need to individually install each bearing within the housing of the profiler. The bearing cartridge also includes a shaft which delivers the rotary motion from an external source to the cam assembly. Both the cam assembly and the bearing cartridge are disposed within a cavity in the housing. The portion of the profiler within which the reciprocating member is housed is also designed to prevent contaminants from entering the interior of the housing. Consequently, the useful life of the profiler and its internal components is increased, while also facilitating maintenance and rebuilding procedures.
