Quick-Ship Serrata-Groove Bushings (SG)

Drill Bushings

Product Information

This bushing can be cast in place or potted, just like a Diamond-Groove Bushing, or can be pressed into an installation hole. The straight knurl provides excellent resistance to rotation, but provides less resistance to axial forces than a diamond knurl. Since the bushing's OD is not ground, the ID must be accurately located during casting or potting to ensure accuracy in the finished tool.

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.

No-Counterbore Option on Long Bushings*
