Boneham HL8816OR Hl Drill Bushing Liner with Head

Product Description

The BONEHAM HL8816OR is an HL-series drill bushing liner with a head, designed to serve as a renewable liner installed into a master bushing or jig plate for precision drill guidance. The liner accepts a 1-inch inside diameter slip or fixed renewable bushing and is manufactured from alloy steel for wear resistance and dimensional stability under repeated drilling operations. With a body outside diameter of 1.375 inches, an overall liner length of 1 inch, and a head outside diameter of 1.5 inches, this liner is sized to standard HL industry specifications. Installation is accomplished by press fit, seating the liner permanently into the jig plate. Machinists, toolmakers, and fixture builders working in production or toolroom environments are the primary installers.

This liner is suited for use in drill jigs, fixture plates, and tooling setups requiring a standardized HL-series liner interface. The headed design retains the liner flush against the top face of the jig plate, resisting axial push-through during drilling operations. It is appropriate for both light-production and high-cycle jig tooling in metalworking, fabrication, and machining shops where consistent hole location is required across multiple workpieces.

Key Features

• HL industry-standard liner code for interchangeability with HL-series renewable bushings
• 1-inch inside diameter accommodates standard HL slip and fixed renewable bushings
• Alloy steel construction provides wear resistance and dimensional stability
• Press fit installation method for secure, permanent seating in jig plates
• Headed design prevents axial push-through during drilling operations
• Head outside diameter of 1.5 inches sits flush at the jig plate surface

Compatibility

Designed as an OEM-style HL-series drill bushing liner compatible with jig plates and master bushings accepting a 1.375-inch outside diameter press-fit liner per HL industry standards.

Installation Notes

Installation of this liner requires pressing it into a correctly bored jig plate hole sized to achieve the proper interference fit for press-fit bushings. A drill press or arbor press with appropriate tooling should be used to drive the liner squarely into the plate without cocking or distorting the bore. Ensure the jig plate hole is clean, free of burrs, and dimensionally verified before pressing. Once installed, a press-fit liner is not intended for routine removal and replacement.
