Boneham PT2812HN Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT2812HN is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. With an inside diameter of 17/64 inches, a body outside diameter of 7/16 inches, and an overall length of 3/4 inches, this bushing provides a tight, consistent bore guide in hardened steel. Manufactured from steel hardened to 60 to 65 HRC, it resists wear under repeated drilling cycles. The headless design allows the bushing to sit flush within a jig plate, making it well suited for applications where a protruding flange would interfere with part clearance or surface contact.

This bushing is used in production drilling jigs, tooling fixtures, and precision machining setups where repeatable hole location is required. It is installed permanently into a jig plate using a press fit method, eliminating the need for additional fasteners or locking hardware. Typical applications include metalworking, machine shops, and manufacturing environments where tight tolerances on hole location are critical. The P industry code designation indicates bushing geometry conforming to ANSI standards for this series.

Key Features

• Press fit installation method — no fasteners or retaining rings required
• Headless design sits flush with jig plate surface for unobstructed workpiece contact
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.0001 to +0.0005 inches for consistent drill guidance
• Conforms to ANSI standards for drill bushing geometry and fit
• Non-renewable, permanent installation style suited for fixed production tooling

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing conforming to ANSI P-series geometry for use in standard jig plates and tooling fixtures.

Installation Notes

Press fit drill bushings are typically 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 installation. Do not hammer the bushing in directly without a proper driver or press to avoid damaging the bore geometry. Once pressed in, this bushing is not designed for removal and reinstallation.
