Boneham P325HL Press Fit Headless Drill Bushing

Product Description

The BONEHAM P325HL is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision in jig and fixture applications. Built to Industry Code P, this bushing features a 0.261 inch inside diameter, a 0.5 inch outside diameter, and a 5/16 inch overall length. It is manufactured from steel for durability under repeated tooling cycles. The headless design allows the bushing to sit flush within the jig plate, making it well suited for applications where a raised flange would interfere with workpiece clearance or clamping setups. Machinists, tool-and-die makers, and precision fabricators are the primary users of this component.

This bushing is used in drill jigs and fixture plates in precision machining environments, both in production shops and toolroom settings. It accepts a G letter-size drill corresponding to the 0.261 inch bore. The press fit installation method means the bushing is driven permanently into a reamed hole in the jig plate without the use of a lock screw or liner, making it appropriate for fixed, high-volume drilling operations where the bushing position does not need to change.

Key Features

• Industry Code P headless press fit configuration for permanent jig installation
• 0.261 inch inside diameter with a tight tolerance of plus 0.0001 to plus 0.0005 inches
• 0.5 inch body outside diameter for a secure interference fit in the jig plate
• 5/16 inch overall bushing length suits thin jig plates and close-tolerance setups
• Steel construction provides resistance to wear from repeated drill passes
• Non-renewable design intended for fixed, long-run drilling applications

Compatibility

Designed as a standard Industry Code P press fit headless drill bushing for use in precision drill jigs and fixture plates where a permanent, non-renewable bushing is required.

Installation Notes

Installation is performed by a machinist or tool-and-die maker using a press to drive the bushing into a properly reamed hole in the jig plate. The receiving hole must be reamed to the correct tolerance to achieve the required interference fit. Do not hammer the bushing in place without a proper press arbor, as this can damage the bore or distort the bushing. Once pressed in, this bushing is not designed for removal or replacement.
