A match drilling system comprising:
- a match drilling tool comprising:
- a body comprising a drilling leg and a fixing leg, said drilling leg being separated from said fixing leg by a gap, wherein said drilling leg defines a cutter guide opening, and wherein said fixing leg defines an alignment pin opening, said alignment pin opening being concentric with said cutter guide opening;
- and
- an alignment pin received in said alignment pin opening;
- a part assembly positioned in said gap, said part assembly comprising at least a pre-drilled part, a target part and a shim positioned between said pre-drilled part and said target part, said pre-drilled part comprising a pre-drilled hole, wherein said alignment pin is biased into said pre-drilled hole;
- a cutter extending through said cutter guide opening into engagement with said target part, said cutter comprises a shoulder axially opposed from a tip, and defining a length from said tip to said shoulder, wherein said length exceeds a combined thickness of said drilling leg and said target part, and wherein said length is less than a combined thickness of said drilling leg, said target part and said shim, thereby ensuring said cutter is capable of forming a through hole in said target part without said cutter contacting said pre-drilled part;
- and
- a screw threadingly engaged with said fixing leg and in contact with said part assembly.
