connecting a replacement cutting insert to said cutter body at a location where said worn or damaged cutting insert was removed; and shaping an unfinished cutting edge comprising said replacement cutting insert and remaining ones of said plurality of cutting inserts to form a continuous unitary finished cutting edge extending substantially entirely along said working length of said cutter body. ### Claim 2 (depends on 1) The method of claim 1 further comprising precision-grinding said continuous unitary finished cutting edge. ### Claim 3 (depends on 1) The method of claim 1 wherein said shaping said unfinished cutting edge is performed without removal of any of said plurality of cutting inserts from said cutter body. ### Claim 4 (depends on 1) The method of claim 1 wherein said shaping said unfinished cutting edge comprises forming a helical continuous unitary finished cutting edge. ### Claim 5 (depends on 1) The method of claim 1 wherein said plurality of cutting inserts are arranged in an end-to-end orientation. ### Claim 6 (depends on 1) The method of claim 1 wherein said replacement cutting insert comprises metal carbide. ### Claim 7 (depends on 1) The method of claim 1 wherein said replacement cutting insert comprises tungsten carbide. ### Claim 8 (depends on 7) The method of claim 7 wherein said replacement cutting insert further comprises cobalt. ### Claim 9 (depends on 1) The method of claim 1 wherein said cutter body comprises a flute formed therein, and wherein said connecting said replacement cutting insert comprising connecting said replacement cutting insert within said flute. ### Claim 10 (depends on 9) The method of claim 9 wherein said flute is helical. ### Claim 11 (depends on 9) The method of claim 9 wherein said replacement cutting insert and said remaining ones of said plurality of cutting inserts are arranged in an end-to-end orientation along said flute. ### Claim 12 (depends on 9) The method of claim 9 wherein cutter body comprises a plurality of pockets along said flute, and wherein said connecting said replacement cutting insert comprising connecting said replacement cutting insert within said a pocket of said plurality of pockets. ### Claim 13 (depends on 12) The method of claim 12 wherein said pocket defines cutting insert support surfaces supporting said replacement cutting insert. ### Claim 14 A method for repairing a cutting tool comprising a cutter body having a working length and a plurality of cutting inserts removably connected to said cutter body, each cutting insert of said plurality of cutting inserts comprising a first end, a second end opposite said first end, and an insert-cutting edge extending from said first end to said second end, wherein at least one cutting insert of said plurality of cutting inserts is a worn or damaged cutting insert, said method comprising: removing said worn or damaged cutting insert from said cutter body; connecting a replacement cutting insert to said cutter body at a location where said worn or damaged cutting insert was removed, said replacement cutting insert comprising a first end, a second end opposite said first end, and an insert-cutting edge extending from said first end to said second end, wherein said insert-cutting edge of said replacement cutting insert and said insert-cutting edges of remaining ones of said plurality of cutting inserts form a continuous unitary finished cutting edge extending substantially entirely along said working length of said cutter body; and precision-grinding said continuous unitary finished cutting edge. ### Claim 15 (depends on 14) The method of claim 14 wherein said connecting said replacement cutting insert is performed without removal from said cutter body of said remaining ones of said plurality of cutting inserts. ### Claim 16 (depends on 14) The method of claim 14 wherein said continuous unitary finished cutting edge is helical. ### Claim 17 (depends on 14) The method of claim 14 wherein said plurality of cutting inserts are arranged in an end-to-end orientation. ### Claim 18 (depends on 14) The method of claim 14 wherein said replacement cutting insert comprises metal carbide. ### Claim 19 (depends on 14) The method of claim 14 wherein said replacement cutting insert comprises tungsten carbide. ### Claim 20 (depends on 19) The method of claim 19 wherein said replacement cutting insert further comprises cobalt.
