Boneham LT8010NW Headless L Drill Bushing Liner 7/8 in

Product Description

The BONEHAM LT8010NW is a headless L-type drill bushing liner designed to guide drill bits and boring tools with precision in jig and fixture applications. It features a 7/8-inch inside diameter and a 1-1/4-inch body outside diameter, with a 5/8-inch liner length. Manufactured from alloy steel with a hardness rating of 60-65 HRC, this bushing liner resists wear during high-cycle drilling operations. Installation is via press fit, seating the liner firmly into a pre-bored jig plate or fixture body without the need for a head flange. It is sized to the L industry standard code, which allows compatible renewable bushings to be swapped in and out during production runs.

This liner is used in precision drilling jigs across metalworking, fabrication, and machining environments. The headless design keeps the liner flush with or below the jig plate surface, making it well suited for applications where a protruding flange would interfere with workpiece seating or clamping. It is typically installed by toolmakers or machining technicians setting up drill jigs for repetitive-hole production work in both job-shop and production-floor settings.

Key Features

• 7/8-inch inside diameter sized to accept compatible renewable drill bushings per L industry code
• 1-1/4-inch body outside diameter for press-fit installation into jig plate bores
• 5/8-inch liner length for compact jig plate applications
• Alloy steel construction with 60-65 HRC hardness for extended wear life
• Headless design eliminates flange interference with workpieces or clamps
• Press fit installation method for secure, permanent seating in the jig body

Compatibility

Designed as an OEM-style L-code headless drill bushing liner for use with compatible renewable drill bushings that match the 7/8-inch inside diameter specification in standard jig and fixture assemblies.

Installation Notes

Installation is performed by toolmakers or machining technicians using a press or arbor press to seat the liner into a precision-bored hole in the jig plate. The mating bore in the jig plate must be machined to the correct interference-fit tolerance before pressing the liner into place. Do not hammer the liner in directly without a proper pressing tool, as this can distort the bore geometry. Verify inside diameter clearance with the renewable bushing before final assembly.
