Boneham AM00000397 Headless Lm Drill Bushing Liner 8mm

Product Description

The BONEHAM AM00000397 is a headless LM-style drill bushing liner designed to guide drill bits and cutting tools with precision in jig and fixture applications. Manufactured from steel and hardened to 60 to 65 HRC, this liner provides the wear resistance required for repetitive drilling operations. With an 8mm inside diameter and a 12mm body outside diameter, it installs via press fit into a master bushing or directly into a jig plate. The overall liner length is 16mm. Tooling and fixture shops, machinists, and maintenance technicians working with drill jigs rely on this type of component to maintain hole-location accuracy across production runs.

This liner is suited for use in drill jig applications where a renewable or slip-renewable bushing system is not required. The headless design sits flush with the jig plate surface, making it appropriate for close-tolerance work where a headed bushing would interfere with part clearance or chip removal. It is appropriate for use in both light-production and maintenance repair settings where consistent hole positioning is critical.

Key Features

• Hardened steel construction rated 60 to 65 HRC for extended wear life
• Headless design sits flush with jig plate surface
• Press fit installation method for secure, repeatable seating
• LM industry code classification for standard interchangeability
• 8mm inside diameter accommodates common metric drill sizes
• Compact 16mm overall length suits thin jig plates and close-clearance fixtures

Compatibility

Designed as an OEM-style replacement or new-installation liner for standard LM-series headless drill bushing applications in metric drill jig fixtures.

Installation Notes

Installation is performed by machinists or tooling technicians using a press or arbor press to seat the liner into a properly reamed hole in the jig plate or master bushing. Ensure the receiving hole is reamed to the appropriate tolerance before pressing the liner into place. Do not hammer the liner directly without a driver to avoid distorting the bore. Verify the inside diameter is clear of burrs or debris before use.
