Boneham PT286HX Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT286HX is a press fit headless drill bushing used to guide drill bits and other cutting tools with precision in jig and fixture applications. Manufactured from hardened steel with a Rockwell hardness of 60 to 65 HRC, this bushing resists wear during repetitive drilling operations. It features a 9/32 inch inside diameter, a 7/16 inch body outside diameter, and a 3/8 inch overall length. The headless design allows the bushing to sit flush within a jig plate, making it well suited for close-tolerance work. Machinists, tool and die makers, and production floor technicians install this type of bushing as a fixed, non-renewable guide in drilling fixtures.

The PT286HX is intended for use in drill jigs where a permanent, flush-mount bushing is required. The headless profile eliminates any protrusion above the jig plate surface, which is useful when workpiece clearance is limited or when multiple bushings are installed in a shared plate. This bushing conforms to ANSI standards and carries the industry code P, identifying it within the standard press fit headless bushing series. It is a direct-installation component requiring no liner or locking mechanism.

Key Features

• Press fit installation method for a permanent, secure fit in the jig plate bore
• Headless design sits flush with the plate surface for low-clearance applications
• Steel construction hardened to 60 to 65 HRC for extended wear resistance
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• ANSI-compliant geometry under bushing industry code P
• Non-renewable fixed bushing — no liner required

Compatibility

Designed as an OEM-style replacement or new-installation component for drill jigs and fixtures requiring a press fit headless bushing with a 9/32 inch inside diameter and 7/16 inch outside diameter per ANSI P-series standards.

Installation Notes

Installation is performed by machinists or tool and die makers using an arbor press to drive the bushing into a precision-bored plate hole. The mating bore in the jig plate must be machined to the correct interference fit tolerance before pressing the bushing in place. Do not hammer the bushing in freehand, as this can damage the bushing bore or distort the jig plate. Once pressed in, this bushing is not intended for removal and reuse.
