CR-DJ-PETERSON DRILL JIG

The Peterson CR-DJ. Drill jig for Corbi/Russwin LFIC cores. Drill out the IC core shear line. Or shear off the I-CORE locking lug from within the core profile on all brands of LFIC core cylinders, with no damage to door hardware. An untouched pin stack means that the core can be decoded for control and master keys.
