Boneham PT284HX Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM PT284HX is a headless, press fit drill bushing manufactured from steel and classified under industry code P. It features a 9/32-inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches, a 7/16-inch body outside diameter, and an overall length of 1/4 inch. This bushing is designed to guide drill bits and other cutting tools with precision during metalworking and machining operations. It is pressed directly into a jig or fixture plate without a head, keeping the top surface flush. Machinists, tool-and-die makers, and production shop technicians typically install and work with this component in jig boring and drilling fixture applications.

The PT284HX is suited for use in drill jigs where a low-profile, flush-mount bushing is required. Its headless design makes it appropriate for applications where clearance above the jig plate is limited or where a smooth top surface is necessary for workpiece contact. This bushing is a non-renewable type, meaning it is pressed permanently into the jig plate rather than being designed for repeated removal and replacement. It fits standard P-series bushing applications in both production and prototype fixture setups.

Key Features

• Headless press fit design seats flush with the jig plate surface
• 9/32-inch inside diameter with tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• 7/16-inch body outside diameter for standard P-series hole preparation
• 1/4-inch overall length suits thin jig plates and tight-clearance fixtures
• Steel construction provides durability in repetitive drilling operations
• Non-renewable, permanent installation type

Compatibility

Designed as an OEM-style replacement and standard fit for P-series press fit headless drill bushing applications in machining jigs and drilling fixtures.

Installation Notes

Installation is performed by pressing the bushing into a properly sized and toleranced hole in the jig plate using an arbor press or similar pressing equipment. The receiving hole must be machined to the correct diameter and finish to achieve proper interference fit. Once pressed in, this bushing is not intended for removal or reuse. Power down all associated equipment before servicing or replacing jig components.
