Boneham P326IF Press Fit Headless Drill Bushing

Product Description

The BONEHAM P326IF 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, this bushing features a 19/64 inch inside diameter, a 1/2 inch outside diameter, and a 3/8 inch overall length. Constructed from steel and hardened to 60 to 65 HRC, it delivers the wear resistance and dimensional stability required in production jig and fixture applications. Installation is permanent — no locking collar or head flange is used — making it well suited for fixed drilling templates where the bushing position does not require regular replacement.

The P326IF is used in machine shop, toolroom, and production environments where close-tolerance hole guidance is required. It fits into a bored or reamed jig plate hole and is pressed in place using an arbor press or similar tooling. Typical applications include drilling fixtures for metalworking and fabrication operations. The inside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures accurate tool guidance and consistent hole location across high-volume production runs.

Key Features

• Press fit installation — no head flange or locking collar required for permanent fixture mounting
• 19/64 inch inside diameter with a tight tolerance of plus 0.0001 to plus 0.0005 inches for precise tool guidance
• 1/2 inch outside diameter and 3/8 inch overall length for compact jig plate fitment
• Steel construction hardened to 60 to 65 HRC for long-term wear resistance
• Meets ANSI standards for drill bushing dimensions and performance
• Non-renewable design suited for permanent, fixed drilling applications

Compatibility

Designed as an ANSI-standard press fit headless drill bushing for use in jig plates and drilling fixtures where a permanent, non-renewable bushing of 19/64 inch bore and 1/2 inch outside diameter is specified.

Installation Notes

Installation is performed by a machinist or toolroom technician using an arbor press — never drive this bushing in with a hammer, as uneven force can damage the bore or the jig plate. The receiving hole in the jig plate must be bored or reamed to the appropriate interference fit tolerance before pressing the bushing in place. Ensure the bushing is seated flush and square with the jig plate surface. Once pressed in, this bushing is not designed for removal and reuse.
