Boneham HL326IM Hl Drill Bushing Liner with Head

Product Description

The BONEHAM HL326IM is an HL-series headed drill bushing liner designed for use in jig plates and tooling fixtures that require repeatable, accurate hole guidance during drilling operations. The liner features a 5/16-inch inside diameter, a 1/2-inch body outside diameter, and a 3/8-inch liner length, making it a compact press-fit component suited for close-tolerance tooling applications. A 3/32-inch head height and 5/8-inch head outside diameter provide a positive seating surface against the jig plate. Constructed from alloy steel, this liner delivers the hardness and wear resistance expected in production drilling environments. Installation is accomplished via press fit, requiring no fasteners or adhesives.

The HL326IM is used in drill jig assemblies where a headed liner is needed to accept renewable drill bushings or to serve as a fixed guide. Typical applications include metalworking shops, aerospace, and general manufacturing tooling. The headed design seats flush against the top face of a jig plate, preventing the liner from being pushed through during use. This part is appropriate for machinists, toolmakers, and fixture designers working with standard HL-series tooling layouts.

Key Features

• 5/16-inch inside diameter for standard drill bushing sizing
• 1/2-inch body outside diameter for press-fit installation into jig plate bores
• 3/8-inch liner length suits medium-thickness jig plates
• 3/32-inch head height with 5/8-inch head outside diameter provides positive axial stop
• Alloy steel construction for high wear resistance and long service life
• Press fit installation method — no fasteners required

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard HL-series drill bushing liner applications in metalworking jig and fixture assemblies.

Installation Notes

Installation is performed by a machinist or toolmaker using a press or arbor press to drive the liner into the jig plate bore. Ensure the receiving bore is machined to the appropriate tolerance for a press fit before installation. Do not hammer the liner in without a proper driver to avoid distorting the head or bore. Verify liner seating is flush and square before mounting any renewable bushings or proceeding with drilling operations.
