Boneham HL3216IM Hl Drill Bushing Liner with Head

Product Description

The BONEHAM HL3216IM is an HL-series drill bushing liner with a headed flange, designed to guide drill bits with precision in jig and fixture applications. It features a 5/16 inch inside diameter, a 1/2 inch body outside diameter, and a 1 inch overall liner length. The head outside diameter measures 5/8 inch with a head height of 3/32 inch. Constructed from alloy steel for durability under repeated drilling cycles, it installs via press fit into a mating slip or lock bushing. This part is used by machinists, toolmakers, and fixture builders in metalworking and production drilling operations.

This HL drill bushing liner is suited for use in drill jigs where renewable bushing liners are required. The headed design provides a positive stop during installation, keeping the liner seated at a consistent depth in the jig plate. It is appropriate for both low-volume prototype work and higher-volume production environments where accurate hole location is critical. The press fit installation method makes it compatible with standard slip and lock bushing systems used across general machining and fabrication shops.

Key Features

• 5/16 inch inside diameter for precise drill bit guidance
• Headed flange design provides positive seating depth control
• Press fit installation into standard mating slip or lock bushings
• Alloy steel construction for wear resistance under repeated use
• 1 inch overall liner length suits standard jig plate thicknesses
• 5/8 inch head outside diameter with 3/32 inch head height

Compatibility

Designed as an OEM-style replacement or direct-fit HL-series drill bushing liner for use in standard slip and lock bushing drill jig systems.

Installation Notes

Installation is performed by qualified machinists or toolmakers using a press or arbor press to seat the liner flush into the mating bushing bore. Ensure the mating bore is clean and free of burrs before pressing in the liner to avoid misalignment or damage to the fit surfaces. Do not hammer the liner in directly without a proper driver or press block, as this may deform the head or body. Always verify inside diameter clearance is appropriate for the drill bit or cutting tool being guided.
