Boneham P5628ME Press Fit Headless Drill Bushing

Product Description

The BONEHAM P5628ME is a press fit headless drill bushing designed to guide drill bits with precision in tooling plates, jigs, and fixtures. With a 39/64-inch inside diameter, a 7/8-inch outside diameter, and an overall length of 1-3/4 inches, this bushing installs permanently into a prepared hole without the use of a retaining head. Manufactured from steel and hardened to 60 to 65 HRC, it provides consistent bore alignment and resists wear through repeated drilling operations. The headless design allows the bushing to sit flush within the tooling plate, making it suitable for applications where surface clearance is critical.

This bushing is used in drill jig assemblies for both production and maintenance tooling in industrial, manufacturing, and machining environments. It is appropriate for applications requiring repeatable hole location accuracy across multiple workpieces. The press fit installation method ensures the bushing remains fixed in the jig plate during drilling cycles, eliminating movement under tool load. Machinists, toolmakers, and jig-and-fixture builders are the primary installers of this component type.

Key Features

• 39/64-inch inside diameter with a close tolerance of +0.0001 to +0.0005 inches for accurate drill guidance
• Hardened steel construction at 60 to 65 HRC for wear resistance in repetitive drilling
• Headless design allows flush installation in tooling plates where head clearance is not available
• Press fit installation method — no fasteners or locking mechanisms required
• Meets ANSI standards for drill bushing dimensions and tolerances
• Bushing industry code P for straightforward cross-referencing with standard jig tooling

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing conforming to ANSI standards for P-style bushings used in drill jig fixtures and tooling plates.

Installation Notes

Installation of press fit bushings requires a drill press or arbor press and a properly sized receiver hole in the jig plate to achieve the correct interference fit. The bushing should be pressed in squarely using a suitable driver — never struck directly with a hammer. Removal should be performed with a dedicated bushing driver or press to avoid damage to the surrounding plate material. Consult applicable shop standards for interference fit tolerances when preparing the receiver bore.
