Boneham AM00000395 Headless Lm Drill Bushing Liner 30mm

Product Description

The BONEHAM AM00000395 is a headless LM-style drill bushing liner designed to provide a precision-ground guide interface for interchangeable drill bushings in jig plate applications. Manufactured from hardened steel with a surface hardness of 60 to 65 HRC, this liner offers the wear resistance and dimensional stability required for high-cycle production drilling. It features a 30mm inside diameter, a 42mm body outside diameter, and an overall length of 56mm. Installation is accomplished via press fit into a prepared jig plate bore. Machinists, toolmakers, and fixture builders in production and prototype environments are the primary installers of this component.

This liner is used in drill jig fixtures where interchangeable renewable bushings must be swapped quickly without disturbing the fixture plate. The headless profile sits flush with the plate surface, making it well suited for applications where a protruding head would interfere with workpiece contact or clamping. It is appropriate for both light-duty prototype fixtures and high-volume production jig plates requiring consistent hole location accuracy across extended run cycles.

Key Features

• Liner industry code LM for compatibility with standard interchangeable bushing systems
• 30mm inside diameter provides the guide bore for renewable drill bushings
• 42mm body outside diameter for press-fit installation into jig plate
• 56mm overall liner length for adequate support depth in thicker fixture plates
• Steel construction hardened to 60 to 65 HRC for long service life under repeated bushing changes
• Headless design allows flush seating in jig plates where surface clearance is critical

Compatibility

Designed as an OEM-style replacement or new-installation liner for standard LM-series interchangeable drill jig bushing systems requiring a 30mm inside diameter headless liner.

Installation Notes

Press-fit installation requires a properly reamed or bored jig plate hole held to the tolerance specified for LM-series liner bores. Use an arbor press with an appropriate driver to seat the liner squarely and fully without damaging the bore. Verify liner seating depth and flush condition before installing renewable bushings. Consult applicable tooling standards for recommended fits and surface finish requirements on the receiving bore.
