A tool adaptable for use with a power drill for the duel purpose of sanding and cutting a work piece without changing tools. The tool includes two components, one for cutting and one for abrading, which are reduced in diameter as required in order to provide suitable cutting and abrading surfaces for future use.

1. A reducible diameter abrade and cut disc for finishing of a work surface, said disc comprising: an abrading pad having a center, a perimeter, a diameter, a rear surface, a front surface, and abrasive material disposed upon said front surface substantially extending outward from said center to said perimeter; and a cutting plate having a front surface, a perimeter, a diameter, and a substantially smooth cutting plate edge along said cutting plate perimeter, said cutting plate edge being substantially free of projections, said cutting plate front surface being juxtaposed to said abrading pad rear surface, whereby said diameters are capable of being reduced by an amount sufficient to eliminate consumed said abrasive material thereby restoring the abrading functionality of said disc. 2. The disc as recited in claim 1, wherein said cutting plate is made of graphite. 3. The disc as recited in claim 1, wherein said abrasive material is generally a compound mixture of sand-like, abrasive particles of varying grain sizes adhered to said abrasive pad. 4. The disc as recited in claim 1, wherein said abrasive pad is sandpaper. 5. The disc as recited in claim 1, wherein said disc further includes an externally threaded connection fixedly attached to said rear surface of said abrading pad, whereby said externally threaded connection engages a drive mechanism. 6. The disc as recited in claim 5, wherein said cutting plate further comprises a hole through its center of rotation, said hole having a predetermined diameter for said externally threaded connection to fit securely within said hole of said cutting plate, whereby said externally threaded connection passes through said hole to engage the drive mechanism. 7. The disc as recited in claim 1, wherein said cutting plate is generally planar and circular in shape. 8. The disc as recited in claim 1, wherein said abrasive pad is generally planar and circular in shape. 9. The disc as recited in claim 1, wherein said cutting plate is attached to said abrading pad. 10. The disc as recited in claim 1, wherein said cutting plate is made of a material of predetermined hardness, whereby said cutting plate edge is capable of being radially cut back when said cutting plate edge contacts an object made of material harder than said predetermined hardness. 11. A reducible diameter abrade and cut disc, said disc comprising: a cutting plate, said cutting plate being generally planar and circular in shape, said cutting plate having an edge surface being substantially free of projections and a center hole along an axis of rotation of said disc; an abrading pad, said abrading pad being generally planar and circular in shape, having an edge surface, an abrading surface and a rear surface; and connection means for attaching said disc to a drive mechanism, said connection means being attached to said abrading pad rear surface and having peripheral dimensions sufficiently sized to be received by said cutting plate center hole, such that said cutting plate is capable of being dispose between said abrading pad and the drive mechanism, whereby said edge surfaces are capable of being worked to eliminate consumed said abrading surface thereby restoring the abrading functionality of said disc. 12. The abrade and cut disc as recited in claim 11, wherein said connection means comprises an externally threaded member attached to said rear surface perpendicular to said planar abrading pad, said threaded connection having a predetermined diameter to fit securely within said cutting plate hole. 13. The abrade and cut disc as recited in claim 11, wherein said abrading pad is sandpaper.
