Boneham AM00000789 Slip-fixed Drill Bushing 11.8mm Id

Product Description

The BONEHAM AM00000789 is a slip-fixed renewable drill bushing used to guide cutting tools with precision in jig and fixture applications. Conforming to ANSI standards and carrying a hardness rating of 60 to 65 HRC, this steel bushing resists wear through repeated drilling cycles. The inside diameter measures 11.8 mm with a tight tolerance of +0.006 to +0.017 mm, ensuring accurate tool guidance. The body outside diameter is 18 mm, and the length under the head is 28 mm. The counterbored head design and slip-fixed installation method allow the bushing to be removed and replaced without disturbing the liner bushing seated in the jig plate.

This bushing is suited for production drilling, reaming, and boring operations in manufacturing and machining environments. The renewable design makes it practical for high-cycle tooling fixtures where bushings require periodic replacement. Machinists, toolmakers, and fixture builders working in metal fabrication, aerospace component production, or general industrial manufacturing will find this bushing compatible with standard liner bushings of the same body diameter. It is classified under industry codes SF and SFM.

Key Features

• Slip-fixed installation method allows quick removal and replacement in production fixtures
• Renewable bushing design extends fixture service life by replacing worn guides without full fixture rework
• Hardness of 60 to 65 HRC provides long wear life in repetitive cutting-tool guidance applications
• Inside diameter tolerance of +0.006 to +0.017 mm delivers consistent tool alignment
• Counterbored head seats securely and resists rotation under load
• Meets ANSI standards for drill bushing dimensions and performance

Compatibility

Designed as an OEM-style replacement renewable drill bushing for use with standard ANSI slip-fixed liner bushings accepting an 18 mm body outside diameter. Industry codes SF and SFM apply.

Installation Notes

Installation is performed by toolmakers or machinists as part of drill jig assembly or maintenance. Ensure the liner bushing bore in the jig plate is clean and free of burrs before inserting the slip-fixed bushing. A locking mechanism appropriate to the fixture design should be used to secure the bushing against rotation during cutting operations. Always de-energize and secure any associated machine before servicing fixture components.
