Claim:
A drill bit sharpening system ( 100 ) using a typical bench grinder ( 200 ) with a sharpening table ( 300 ) for refurbishing a dull or broken drill bit ( 110 ), wherein said system ( 100 ) comprises: (a) a bench grinder ( 200 ) having a motor ( 210 ) operatively coupled to a rotating shaft ( 220 ), wherein the rotating shaft ( 220 ) comprises a sharpening wheel ( 230 ) disposed on a shaft end ( 222 ), wherein the bench grinder ( 200 ) further comprises a generally planar positioning table ( 240 ) disposed in an anterior position thereon with respect to a sharpening wheel face ( 232 ); a generally planar rigid sharpening table ( 300 ) having a top table surface ( 310 ), a bottom table surface ( 320 ) opposite to and generally parallel with the top table surface ( 310 ), a first table edge ( 330 ), third table edge ( 340 ) proximal to the sharpening wheel face ( 232 ), a fifth table edge ( 345 ), a sixth table edge ( 350 ), a fourth table edge ( 360 ), and a second table edge ( 370 ) opposite to and parallel with the sixth table edge ( 350 ) and the fourth table edge ( 360 ); and c) a positioning component ( 400 ) disposed on the table top surface ( 310 ) comprising an elongated planar wall component ( 410 ) having a first wall component edge ( 411 ) and a second wall component edge ( 412 ), wherein the positioning component ( 400 ) further comprises an elongated planar floor component ( 420 ) having a first floor component edge ( 421 ) and a second floor component edge ( 422 ), wherein the first floor component edge ( 421 ) is perpendicularly attached to the second wall component edge ( 412 ), wherein the positioning component 400 comprises a generally “L” shaped cross-section in a transverse plane; wherein for use, the sharpening table ( 300 ) is attached to the positioning table ( 240 ) of the bench grinder ( 200 ), wherein the energized motor ( 210 ) rotates the sharpening wheel ( 230 ) via the rotating shaft ( 220 ), wherein for operation the drill bit ( 110 ) is placed against the positioning component ( 400 ) on the sharpening table ( 300 ) and held against the rotating sharpening wheel face ( 232 ) for shaping, wherein the drill hit ( 110 ) is manually rotated against the sharpening wheel face ( 232 ) via a users fingers on the drill bit ( 110 ); wherein the bottom table surface ( 320 ) comprises a table mount ( 390 ) disposed thereon for removably and rigidly attaching to the positioning table ( 240 ).
