Boneham L6416NC Headless L Drill Bushing Liner

Product Description

The BONEHAM L6416NC is a headless L-style drill bushing liner designed to guide drill bits with precision in jig and fixture applications. It features a 3/4-inch inside diameter and a 1-inch body outside diameter, with an overall liner length of 1 inch. Constructed from alloy steel hardened to 60-65 HRC, this liner provides the wear resistance needed for repetitive drilling operations. Installation is by press fit, seating the liner securely into a drill jig plate or receiver bushing without the need for a locking head. Licensed machinists, toolmakers, and CNC setup technicians typically handle this type of component during fixture assembly or tooling maintenance.

This liner is suited for use in drill jigs, fixtures, and tooling plates where a renewable or slip-fixed bushing system is required. The headless L-series liner seats flush or below the jig plate surface, making it appropriate for close-tolerance hole patterns where a flanged head would interfere with workpiece clearance. It is well-suited to production environments where consistent hole location and repeatability are critical. Weighing 0.125 pounds, the part ships individually.

Key Features

• 3/4-inch inside diameter for precise drill bit guidance
• 1-inch body outside diameter for standard receiver bushing fitment
• 1-inch overall liner length for typical jig plate depths
• Alloy steel construction hardened to 60-65 HRC for extended wear life
• Press fit installation method for secure, tool-free seating in the receiver
• Headless L-series design allows flush or sub-flush mounting in jig plates

Compatibility

Designed as an OEM-style replacement or new-install liner for standard L-series drill bushing receiver systems used in industrial jig and fixture tooling.

Installation Notes

Press fit installation requires a drill press or arbor press to seat the liner evenly into the receiver bushing without cocking or galling the bore. Ensure the receiver bushing bore and the liner outside diameter are clean and free of burrs before pressing. Do not use a hammer directly on the liner face, as this can distort the inside diameter and affect drill guidance accuracy. Follow applicable shop safety procedures and consult tooling engineering documentation for interference fit tolerances.
