Boneham AM00000657 Drill Bushing Pm 7.1 in Id

Product Description

The BONEHAM AM00000657 is a press fit headless drill bushing with an industry code designation of PM, manufactured from hardened steel for precision tooling applications. It features a 7.1-inch inside diameter and is designed to guide cutting tools accurately during drilling operations. With a hardness rating of 60 to 65 HRC, the bushing provides excellent wear resistance under repeated use. Installation is accomplished by pressing the bushing directly into a jig or fixture plate without a retaining head, making it suitable for flush-mount setups where a low-profile configuration is required. This component is typically installed by machinists, toolmakers, and maintenance professionals working with drill jigs.

This bushing is suited for use in drill jig fixtures across manufacturing, fabrication, and maintenance environments. The PM industry code identifies it within the standard headless press fit bushing series, conforming to ANSI standards. It is appropriate for applications where a permanent or semi-permanent bushing installation is needed and where precise hole location and tool guidance are critical to part quality. The non-renewable design means it is pressed in and replaced as a complete unit rather than relying on a liner bushing system.

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing for use in standard drill jig fixtures requiring a PM-series bushing per ANSI specifications.

Installation Notes

Installation is performed by toolmakers or machinists using a press or arbor press to drive the bushing into a properly reamed jig plate bore. Ensure the receiving bore is sized and finished to the bushing's outside diameter tolerance before pressing to avoid bushing damage or bore distortion. Do not use a hammer directly on the bushing face. Once pressed in, this non-renewable bushing is not designed for removal and reinstallation.
