ABSTRACT:
The deburring and reaming tool of this invention has a housing with a rotatable driven or supporting member that engages one end of a torsional-compression spring, the other end of which engages a reciprocatable, rotatable intermediate member having radially off-set lugs or projections that are engagable with slots in a pair of side-by-side cutter members slidable carried transverse the other end of the housing for simultaneous extension and retraction. Means are provided in the housing to adjust and limit the degree of rotation of the intermediate member and to extend and retract the intermediate member and its lugs or projections into and out of engagement with the slots in the cutter members. The tool provides a controllable and substantially constant resilient force holding the cutter members into engagement with the bore of the work piece, irrespective of changing diameters of the bore and controllable and substantially constant rigid force on the cutter members in the presence of burrs to be removed in the first and last portions of the bore to be reamed.
