Boneham P208FF Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P208FF is a headless, press fit drill bushing used to guide cutting tools with precision during drilling, reaming, and boring operations in jig and fixture setups. Manufactured from steel, this bushing features a 0.1695 inch inside diameter, a 5/16 inch body outside diameter, and a 1/2 inch overall length. The inside diameter is held to a tight tolerance of +0.0001 to +0.0004 inches, ensuring accurate tool guidance and repeatable hole location across production runs. It installs without hardware, pressed directly into a jig plate or fixture body for a clean, flush-mounted fit. Machinists, toolmakers, and fixture builders are the primary users of this component in both job shop and production environments.

This bushing is suited for use in drill jigs, machining fixtures, and tooling plates where a permanent, non-renewable guide is required. The headless design keeps the top face of the fixture surface unobstructed, making it well suited for close-tolerance layouts where adjacent bushings or workpiece clearance is limited. Its steel construction handles standard drilling and reaming loads in light to medium production applications.

Key Features

• Headless design for flush, low-profile installation in drill jigs and fixtures
• Press fit installation method — no fasteners or locking rings required
• 0.1695 inch ID with tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• 5/16 inch body outside diameter, 1/2 inch overall length
• Steel construction for durability under repeated drilling and reaming cycles
• Non-renewable design intended as a permanent fixture component

Compatibility

Designed as a P-series OEM-style press fit headless drill bushing for use in standard drill jig and fixture plates accepting a 5/16 inch outside diameter bushing bore.

Installation Notes

Installation is performed by toolmakers or machinists using a bushing press or arbor press to seat the bushing flush with the fixture plate surface. Ensure the receiving bore in the jig plate is machined to the correct interference fit tolerance before pressing. Do not use a hammer directly on the bushing face, as this can damage the bore geometry or crack the surrounding plate material. Follow applicable shop floor safety procedures and de-energize any powered fixtures before servicing.
