Boneham PT8810OJ Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM PT8810OJ is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. This Industry Code P bushing features a 61/64 inch inside diameter and a 1-3/8 inch body outside diameter, with an overall length of 5/8 inch. Constructed from steel, it is pressed directly into a fixture plate without a locking head, keeping the bushing flush with the work surface. Machinists, toolmakers, and maintenance technicians install this type of bushing when a permanent, low-profile guide is required in a drill jig setup.

This bushing is suited for metal fabrication shops, tool and die operations, and production machining environments where repeatable hole location is critical. The headless design is preferred when clearance above the jig plate is limited or when a smooth, unobstructed surface is needed. Its steel construction provides the hardness and wear resistance required for high-cycle drilling operations in both job shop and production floor settings.

Key Features

• Press fit installation — no retaining ring or set screw required
• Headless design keeps the bushing flush with the jig plate surface
• 61/64 inch inside diameter with a tight tolerance of +0.0002 to +0.0006 inch for accurate tool guidance
• 1-3/8 inch body outside diameter for secure seating in the fixture bore
• 5/8 inch overall length provides stable guidance depth
• Steel construction delivers durability in repetitive drilling applications
• Industry Code P designation for straightforward cross-referencing and replacement

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for standard drill jig fixtures using Industry Code P press fit headless bushings with a 61/64 inch inside diameter and 1-3/8 inch outside diameter.

Installation Notes

Press fit drill bushings are typically installed by toolmakers or machinists using an arbor press or hydraulic press — never drive with a hammer, as uneven force can damage the bore or distort the bushing. The receiving hole in the jig plate must be machined to the correct tolerance to achieve the proper interference fit. Ensure the fixture and workpiece are properly clamped and all tooling is secured before beginning drilling operations. Follow applicable shop safety and machine guarding practices during installation and use.
