Boneham AM00000315 Press Fit Drill Bushing Hm 8.9in

Product Description

The BONEHAM AM00000315 is a press fit headless drill bushing manufactured to HM industry code standards. It is designed to guide drill bits and cutting tools with precision in jig and fixture applications. Made from steel with a hardness rating of 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. It installs directly into a prepared hole in a drill jig plate without a head flange, making it well-suited for applications where a flush or near-flush surface is required. The inside diameter is 8.9 inches with a tolerance of plus 0.005 to plus 0.014 mm, ensuring consistent tool guidance. Machinists, tool and die makers, and fixture builders typically work with this component.

This drill bushing is intended for use in precision drilling fixtures, jig plates, and production tooling setups where repeatable hole location is critical. The headless press fit design allows the bushing to be permanently installed in a jig body without protruding hardware interfering with workpiece clamping or fixturing. It is appropriate for both one-off fixture builds and higher-volume production tooling environments requiring dimensional consistency.

Key Features

• HM industry code classification for standardized jig bushing interchangeability
• Press fit installation method for secure, permanent seating in jig plates
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Headless design provides a flush profile that does not interfere with workpiece fixturing
• Inside diameter tolerance of plus 0.005 to plus 0.014 mm for precise tool guidance
• Meets ANSI standards for drill bushing dimensional requirements

Compatibility

Designed as an OEM-style replacement or direct-fit bushing for drill jig plates and fixture tooling applications conforming to ANSI HM bushing standards.

Installation Notes

Installation is typically performed by a machinist or tool and die maker using an arbor press to seat the bushing flush into the prepared jig plate bore. The receiving hole must be machined to the appropriate press fit tolerance before installation. Never drive the bushing in with an impact tool, as this can damage the bushing bore or distort the jig plate. Once pressed in, the bushing is not intended for removal and reuse.
