Product Information
P bushings are the most-popular and least-expensive type of drill bushing. P bushings are permanently pressed into the jig plate, usually flush with the top surface. They are generally used for single-operation drilling or reaming, when you do not expect to replace bushings during the tooling's lifetime. P bushings can be mounted closer together than headed bushings, but offer less resistance to heavy axial loads. Quick-Ship Drill Bushings are popular bushing sizes that we do our best to keep in stock and ready for same-day shipment 100% of the time. These bushings include most common ID drill sizes. Complete part numbers for all quick-ship P bushings are listed in the tables below.
