1-1/2 to 1-3/16
20 TPI
Coarse

In the world of router table inserts, there are 2 distinct bushing sizes… 1-3/16" (Porter Cable®) and 1-1/2" (Oak Park®, Lee Valley®). If you happen to own the 1-1/2" size (with 1-3/4" counter bore), you may have trouble finding bushings for all the jigs because most use or come with 1-3/16" bushings.

Your problem has been solved.

This bushing set converts from 1-1/2" to 1-3/16". A stepped ring is set into the 1-1/2" hole and then into it, you place the 1-3/16" bushing. A special nut supplied with the ring holds everything in place.

Please look carefully at the threads on your bushings. Two threads exist and we offer both.
