Boneham P888OR Press Fit Headless Drill Bushing 1in Id

Product Description

The BONEHAM P888OR is a headless drill bushing designed for press fit installation in drill jigs and fixture plates. It carries an industry code of P and accepts a 1-inch inside diameter with a 1-3/8-inch outside diameter, providing a robust wall section for accurate drill guidance. The overall length is 1/2 inch. Manufactured from steel hardened to 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. It is a non-renewable, permanent-installation type, meaning it is pressed directly into the jig body without a locking liner. Machinists, toolmakers, and fixture builders working in production or job-shop environments are the primary installers of this component.

This bushing fits applications where a flush, headless profile is required — situations where a headed bushing would interfere with part seating or clamping. It is suited for ferrous and non-ferrous drilling operations in both manual and CNC drill-jig setups. The 1-inch bore accommodates standard drill shanks and step drills of matching diameter. Its ANSI-standard dimensions make it a straightforward replacement or new-build component for any fixture designed to that specification.

Key Features

• Press fit installation — no retaining ring or liner required
• Headless profile eliminates interference with workpiece clamping surfaces
• Hardened steel construction at 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.0002 to +0.0006 inches for precise drill guidance
• ANSI-standard dimensions for compatibility with standard jig plate designs
• Non-renewable design — permanent press-in installation

Compatibility

Designed as an ANSI-standard press fit headless drill bushing for use in drill jigs and fixture plates requiring a 1-inch bore, 1-3/8-inch OD, and 1/2-inch overall length.

Installation Notes

Press fit bushings are installed by toolmakers or machinists using an arbor press or hydraulic press. The receiving hole in the jig plate must be machined to the correct interference fit tolerance before pressing the bushing into place. Once pressed in, the bushing is not intended for removal or replacement. Always verify bore alignment and hole finish before installation to avoid damage to the bushing or jig body.
