Boneham L8822OR Headless L Drill Bushing Liner 1in Press Fit

Product Description

The BONEHAM L8822OR is a headless L-type drill bushing liner designed for use in jig plates and tooling fixtures where repeatable hole location is critical. This liner accepts a removable drill bushing and is installed into the jig body via press fit, creating a permanent seat for interchangeable slip-renewable bushings. Manufactured from alloy steel with a hardness rating of 60 to 65 HRC, the L8822OR measures 1 inch inside diameter and 1-3/8 inches body outside diameter, with a liner length of 1-3/8 inches. It is installed by machinists, tool-and-die makers, and precision fabricators building or maintaining drill jigs.

This liner is suited for production drilling, reaming, and boring operations where fixed jig tooling is required. The headless design sits flush with the jig plate surface, making it appropriate for applications where a protruding flange would interfere with workpiece clamping or part travel. Press fit installation ensures the liner remains stationary under repeated use without additional fasteners. Typical applications include fixture plates in machine shops, assembly jigs in manufacturing lines, and tooling setups in metalworking and aerospace fabrication environments.

Key Features

• 1 inch inside diameter accommodates standard drill bushing OD sizes in the L series
• 1-3/8 inch body outside diameter for press fit installation into jig plate bores
• 1-3/8 inch liner length provides sufficient engagement depth for stable bushing retention
• Alloy steel construction hardened to 60 to 65 HRC for wear resistance under repeated tooling cycles
• Headless design sits flush with jig surface, eliminating flange interference during fixturing
• Press fit installation method locks liner in place without secondary fasteners

Compatibility

Designed as an OEM-style replacement or new-installation liner for L-series headless drill bushing systems used in standard jig plate tooling applications.

Installation Notes

Press fit installation requires an arbor press or hydraulic press sized to the liner OD. The receiving bore in the jig plate must be machined to the appropriate tolerance for an interference fit before installation. Do not drive the liner with a hammer or impact tool, as this can damage the bore seat or distort the liner ID. Verify liner seating is fully flush or to specified depth before installing the renewable drill bushing.
