Boneham LT5616XMH Headless L Drill Bushing Liner

Product Description

The BONEHAM LT5616XMH is a headless L-type drill bushing liner used in jig and fixture setups to guide drill bits with precision. It features a 5/8 inch inside diameter, a 7/8 inch body outside diameter, and a 1 inch liner length. Constructed from alloy steel with a hardness rating of 60-65 HRC, this liner is built to resist wear in high-cycle drilling operations. Installation is accomplished via press fit, seating the bushing securely into a jig plate or fixture block. It is suited for machine shops, toolrooms, and production environments where accurate hole location is critical.

This liner is used in drill jig applications across manufacturing and fabrication environments. The headless L-type profile allows it to sit flush within a jig plate without a head protruding above the surface, making it appropriate for setups where clearance is limited or a flush-mount configuration is required. Machinists, toolmakers, and fixture builders working in both low-volume prototype and high-volume production settings will find this liner fits standard L-series bushing applications.

Key Features

• 5/8 inch inside diameter for consistent drill guidance
• 7/8 inch body outside diameter for press fit into standard L-series jig plate bores
• 1 inch liner length for adequate bushing support depth
• Alloy steel construction rated at 60-65 HRC for extended wear life
• Headless L-type profile allows flush mounting in jig plates
• Press fit installation method for secure, non-rotating seating

Compatibility

Designed as an OEM-style replacement or direct-use component for standard L-series headless drill bushing liner applications in drill jig fixtures and tooling plates.

Installation Notes

Installation is performed by a machinist or toolmaker using an arbor press to achieve the required press fit into the jig plate bore. Ensure the receiving bore is clean, dimensionally correct, and free of burrs before pressing the liner into place. Do not hammer the bushing in directly without a press tool, as this can damage the bore or distort the bushing. Verify alignment and seating depth before proceeding with drilling operations.
