Boneham L17616 Headless L Drill Bushing Liner 2.25in Id

Product Description

The BONEHAM L17616 is a headless L-series drill bushing liner designed for use in jig and fixture applications requiring precise hole location and repeatable drilling accuracy. With a 2.25-inch inside diameter and a 2.75-inch body outside diameter, this liner accepts slip-renewable or fixed drill bushings and is installed into the jig plate via press fit. Manufactured from alloy steel and hardened to 60-65 HRC, the L17616 provides a durable wear surface that extends fixture service life in production drilling environments. Machinists, tool-and-die makers, and fixture builders are the primary installers.

This liner is suited for production drilling jigs and fixtures in metalworking, fabrication, and machining operations. 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. With a 1-inch liner length and press fit installation, it is compatible with standard jig plate thicknesses common in industrial tooling setups. No specific OEM system compatibility data was provided with this part.

Key Features

• 2.25-inch inside diameter accommodates standard drill bushing OD sizes in the L series
• Alloy steel construction hardened to 60-65 HRC for long wear life under repeated drilling cycles
• Headless design sits flush with jig plate surface, eliminating flange interference
• Press fit installation provides secure, non-rotating retention in the jig plate bore
• 1-inch liner length suits standard jig plate thicknesses used in production tooling
• Industry liner code L for straightforward cross-reference and replacement identification

Compatibility

Designed as an OEM-style replacement or new-build component for industrial drilling jigs and fixtures requiring a headless L-series liner with a 2.25-inch inside diameter and press fit retention.

Installation Notes

Press fit installation requires an arbor press or hydraulic press sized appropriately for the liner OD and jig plate bore. Ensure the receiving bore is machined to the correct interference fit tolerance before installation. Do not drive the liner in with impact tools, as this can distort the bore geometry. Follow applicable shop safety and tooling standards when pressing components into hardened jig plates.
