Boneham PT5610LZ Headless Drill Bushing 37/64 in Id Steel

Product Description

The BONEHAM PT5610LZ is a press fit headless drill bushing designed to guide drill bits with precision during machining and fabrication operations. With an inside diameter of 37/64 inches and a body outside diameter of 7/8 inches, this bushing installs flush into a jig plate without a protruding head, keeping the work surface clear. The overall bushing length is 5/8 inches. Constructed from steel with an inside diameter tolerance of +0.0001 to +0.0005 inches, it holds tight dimensional control for repeatable hole location across production runs. Machinists and tool-and-die professionals install this type of bushing in drill jigs and fixtures where a low-profile, permanent-mount solution is required.

This bushing is suited for use in drill jig plates and fixture bodies in both job-shop and production environments. The headless, press fit design makes it appropriate for applications where the bushing must sit flush with or below the jig surface, such as close-clearance drill guides or stacked fixture assemblies. Industry code P identifies its dimensional series for cross-reference purposes within standard bushing catalogs. It is not a renewable bushing, meaning it is intended as a permanent installation rather than a slip-renewable replacement.

Key Features

• 7/8 inch body outside diameter and 5/8 inch overall length
• Steel construction for durability under repeated drilling cycles
• Bushing industry code P for standard catalog cross-reference

Compatibility

Designed as an OEM-style permanent press fit drill bushing for use in steel or cast-iron jig plates and fixture bodies requiring a 7/8 inch outside diameter bore.

Installation Notes

Press fit bushings are typically installed by a machinist or tool-and-die technician using an arbor press or hydraulic press to seat the bushing flush into a precision-bored hole in the jig plate. The receiving bore in the fixture should be dimensionally matched to the bushing outside diameter to achieve proper interference fit. Always de-burr and clean the bore before pressing the bushing to avoid damage to the bushing or the fixture. Because this is a non-renewable bushing, removal will likely require destruction of the bushing or the surrounding material.
