Quick-Ship Head Press-Fit Bushings (H)

Drill Bushings

Product Information

H Bushings are similar to P bushings, but with a head to resist heavy axial loads. H bushings are permanently pressed into the jig plate. They are generally used for single-operation drilling or reaming, when you do not expect to replace bushings during the tooling's lifetime. The head can be left exposed, or recessed by counterboring the installation hole.

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 H bushings are listed in the tables below.
