Screw-On Pilot Assembly

This pilot assembly screws on the end of a regular Critchley Reamer in place of a nut, transforming it into an aligning reamer. If you use a pilot assembly with your GENUINE CRITCHLEY REAMER it may not be necessary to buy a special reamer for King Pins. One reamer will do both jobs.
