Boneham PT8810OP Headless Drill Bushing 63/64 in Id Steel

Product Description

The BONEHAM PT8810OP is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. This bushing features a 63/64 inch inside diameter, a 1-3/8 inch body outside diameter, and a 5/8 inch overall length. Manufactured from steel and hardened to 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling operations in production environments. The inside diameter tolerance of +0.0002 to +0.0006 inches ensures consistent tool guidance and hole location accuracy. Machinists, tool and die makers, and production shop technicians install this bushing as part of drill jig assemblies.

This bushing is suited for use in drill jigs, fixtures, and tooling plates across general metalworking, fabrication, and production machining environments. The headless, press fit design allows it to seat flush within the jig body without a protruding flange, making it appropriate for applications where clearance is limited or a smooth top surface is required. It conforms to ANSI standards and carries the Bushing Industry Code P designation, which defines its dimensional series within the standard headless press fit classification.

Key Features

• Press fit installation method — seats securely into the jig body without fasteners
• Headless design provides a flush, low-profile seating surface
• Steel construction hardened to 60 to 65 HRC for long service life under repeated tool contact
• Inside diameter tolerance of +0.0002 to +0.0006 inches for precise tool guidance
• ANSI-conforming dimensions under Bushing Industry Code P
• Not renewable — intended as a permanent press fit installation

Compatibility

Designed as a standard ANSI Bushing Industry Code P press fit headless drill bushing for use in drill jigs and fixtures requiring a 63/64 inch tool guide bore.

Installation Notes

Installation is typically performed by a machinist or tool and die technician using an arbor press to drive the bushing into a properly reamed or bored hole in the jig plate. The receiving hole must be dimensioned to achieve the correct interference fit as specified by ANSI jig bushing standards. Do not hammer the bushing directly with a steel face hammer, as this can damage the bore or distort the OD. Once pressed in, this bushing is not designed for removal and replacement.
