Boneham P4028JB Headless Drill Bushing 11/32 Id 5/8 Od Steel

Product Description

The BONEHAM P4028JB is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Classified under industry code P, this bushing features an 11/32-inch inside diameter and a 5/8-inch outside diameter, with an overall length of 1.75 inches. Manufactured from steel, it provides the hardness and wear resistance required for repetitive drilling operations in production environments. The press fit installation method holds the bushing securely in the jig plate without a locking head, keeping the working surface flush. Machinists and toolmakers install this component when building or maintaining drill jigs used in metalworking and fabrication shops.

This bushing is suited for use in drill jig plates where a headless, flush-mount profile is required. The P industry code designates a standard press fit style commonly used in fixed-location drilling applications where the bushing is not intended to be frequently replaced. It is appropriate for light-to-medium production runs in machine shops, tool rooms, and manufacturing facilities where consistent hole location accuracy is critical. The tight inside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures reliable tool guidance across repeated operations.

Key Features

• Press fit installation for secure, permanent seating in the jig plate
• Headless design provides a flush working surface with no protruding flange
• 11/32-inch inside diameter with a tolerance of plus 0.0001 to plus 0.0005 inches for precise tool guidance
• 5/8-inch outside diameter and 1.75-inch overall length for standard jig plate fitment
• Steel construction delivers hardness and durability for repetitive drilling cycles
• Non-renewable bushing type - intended for fixed, long-term installation

Compatibility

Designed as a standard P-code press fit headless drill bushing for use in drill jigs and fixtures requiring an 11/32-inch inside diameter and 5/8-inch outside diameter bore.

Installation Notes

Press fit bushings are installed by machinists or toolmakers using an arbor press or hydraulic press - never drive them in with a hammer, as that can damage the bushing bore or distort the jig plate. Ensure the receiving hole in the jig plate is reamed to the correct interference fit diameter before installation. The bushing should be pressed in squarely and seated fully to its shoulder depth. Once pressed in, this non-renewable bushing is not designed for removal and reinstallation.
