A pivoting split thread chasing die for rethreading and cleaning damaged or inhibited studs or bolts; and a method of manufacturing the die. The identical main body halves of the pivoting split die, when assembled together with an assembly pin form a pivoting split die with opposing front and rear faces and a hexagonal outside periphery. Threads are formed on the inside periphery of the pivoting split die allowing for engagement with the threads of a stud or bolt. One or more material reliefs are formed on the inside periphery of the pivoting split die to enhance the cleaning and rethreading ability of the pivoting split die threads. These reliefs also serve as points for which debris can escape while performing a rethreading procedure. To rethread or clean a damaged or inhibited bolt or stud, apply an appropriate lubricant to the area to be rethreaded or cleaned. Open up the pivoting split die and install around existing good threads of the stud or bolt and close pivoting split die until minimal closure gap exists. Select the appropriate wrenching tool and work the pivoting split die back and forth (counter-clockwise and clockwise) over the damaged or inhibited threads until the pivoting split die begins to move about the threads freely.
