Boneham P6412LU Press Fit Headless Drill Bushing

Product Description

The BONEHAM P6412LU is a press fit headless drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Built to Industry Code P specifications, it features a 35/64 inch inside diameter, a 1 inch outside diameter, and a 3/4 inch overall length. Constructed from steel, this bushing is pressed directly into a jig plate without the use of a locking head, keeping the plate surface flush and unobstructed. It is intended for permanent or semi-permanent installations in production tooling environments where accurate hole location and consistent repeatability are required across multiple workpieces.

This bushing is suited for use in drill jigs and fixture tooling on machine shop floors, production lines, and tool rooms. It is commonly installed by toolmakers, machinists, and fixture builders who require repeatable hole positioning under sustained drilling cycles. The 35/64 inch bore accommodates standard drill rod and tooling shanks of that diameter, and the steel construction holds up under the side loads and abrasion typical of high-volume drilling operations.

Key Features

• Press fit installation — no head or collar, keeps jig plate surface flush
• 35/64 inch inside diameter with a close tolerance of +0.0001 to +0.0005 inches for accurate tool guidance
• 1 inch outside diameter for a secure interference fit in the jig plate bore
• 3/4 inch overall length provides stable tool guidance depth
• Steel construction for abrasion resistance under repeated drilling cycles
• Non-renewable design suited for permanent fixture installations

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for use in standard press fit drill jig plates conforming to Industry Code P bushing specifications.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to drive the bushing into a precision-bored jig plate hole. The jig plate bore must be machined to the correct interference fit dimension to ensure proper retention. Do not hammer the bushing in directly without a driver or press tool, as this can damage the bushing bore or distort the outer diameter. Verify inside diameter clearance to the intended drill rod or tooling shank before pressing into the fixture.
