Boneham SP00008880 Press Fit Headless Drill Bushing

Product Description

The BONEHAM SP00008880 is a headless press fit drill bushing with an industry code designation of P, designed to guide drill bits and other cutting tools with precision during machining operations. Manufactured from steel, this bushing features a 55/64-inch inside diameter and a 1-3/8-inch body outside diameter, with an overall length of 5/8 inch. It is installed by pressing directly into a jig plate or fixture without a locking collar or head flange, making it suited for applications where a flush or low-profile installation is required. Machinists and tool and die tradespeople rely on this style of bushing to maintain hole location accuracy across production runs.

This bushing is used in drill jig fixtures found in metalworking, fabrication, and manufacturing environments. The headless design keeps the bushing flush with the jig plate surface, which is useful when clearance above the work surface is limited or when multiple operations share the same fixture. The P-series industry code identifies the bushing geometry and allows direct cross-referencing with standard drill bushing specifications. Sold individually, this part is appropriate for both new fixture builds and replacement of worn bushings in existing tooling setups.

Key Features

• Press fit installation method for secure, tool-free retention in the jig plate bore
• Headless design provides a flush profile with no flange above the plate surface
• 55/64-inch inside diameter guides drill bits and reamers with close dimensional control
• 1-3/8-inch body outside diameter for stable seating in the fixture
• 5/8-inch overall length suits standard jig plate thicknesses
• Steel construction provides wear resistance for repeated drilling cycles

Compatibility

Designed as an OEM-style replacement or new-installation component for drill jig fixtures requiring a P-series headless press fit bushing with a 55/64-inch inside diameter and 1-3/8-inch outside diameter.

Installation Notes

Installation is performed by pressing the bushing into a prepared bore in the jig plate using an arbor press or similar press equipment — do not drive with a hammer directly on the bushing face. Ensure the receiving bore is machined to the correct interference fit tolerance before pressing. Remove all chips and debris from the bore before installation. Removal requires a bushing press or extraction tool designed for headless bushings to avoid damaging the surrounding fixture material.
