ABSTRACT:
A portable device (10) for excising an axial slot (8) into the boundary surface (16) of an aperture (15). The device (10) includes a guide (11), a machining implement (12) and a power source (13). The guide (11) has proximal and distal ends (19 and 20) with an exterior configuration including at least a horn surface (26) and a transitional surface (30). A reaction flange (21) extends radially outwardly from the proximal end (19) of the guide (11). A slideway (35) extends longitudinally within the guide (11), and a tracking channel (36) extends radially outwardly from the slideway (35) to penetrate the guide (11) along the axial extent thereof. The machining inplement (12) includes a drive shaft (40) that is axially translatable within the slideway (35) and a plurality of teeth (45) that are progressively stepped with the shortest tooth (45 A) being located in proximity in the medial portion (46) of the shaft (40) and with the highest tooth (45N) being located in proximity to the distal end (48) of the shaft (40). The power source (13) is connected to, and selectively protracts and retracts, the shaft (40). When the machining implement (12) is protracted relative to the guide (11) the assembled combination can be operable received through an aperture (15) in a workpiece (14) to excise a slot (81) in the boundary surface (16) of the aperture (15) with access to only one side of the workpiece (14).
