Boneham P268HJ Press Fit Headless Drill Bushing

Product Description

The BONEHAM P268HJ is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to ANSI standards, this bushing features a 0.257 inch (Letter F) inside diameter and a 13/32 inch body outside diameter, with an overall length of 1/2 inch. Constructed from hardened steel rated at 60 to 65 HRC, it delivers consistent bore alignment and long service life under repeated drilling cycles. The headless design keeps the bushing flush with the jig plate surface, making it well suited for close-tolerance work where a flange would interfere with tooling clearance.

This bushing is used in drill jig assemblies across metalworking, machining, and manufacturing environments. The press fit installation method seats the bushing permanently into the jig body without a retaining collar, making it appropriate for fixed-location applications where the bushing is not intended to be rotated or replaced during a production run. Typical users include tool and die makers, machine shop technicians, and manufacturing engineers working with precision drill fixtures.

Key Features

• Press fit installation method for permanent, rigid seating in jig plates
• Headless design allows flush mounting with no flange protrusion
• Hardened steel construction rated at 60 to 65 HRC for wear resistance
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Meets ANSI standards for drill bushing dimensions and performance
• Non-renewable design optimized for fixed, high-volume drilling setups

Compatibility

Designed as an ANSI-standard press fit headless drill bushing suitable for use in precision drill jig fixtures requiring a 0.257 inch bore guide.

Installation Notes

Installation is performed by pressing the bushing into a prepared hole in the jig plate using an arbor press or hydraulic press — never drive with a hammer, as this can distort the bore or damage the bushing seating surface. Ensure the receiving hole is reamed to the appropriate press fit tolerance before installation. Once seated, this bushing is not intended for removal; use a renewable bushing design if serviceability is required. Follow applicable shop safety procedures and confirm bore alignment before beginning production drilling.
