Boneham P648NC Press Fit Headless Drill Bushing

Product Description

The BONEHAM P648NC is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to Industry Code P, this bushing features a 0.75-inch (3/4 inch) inside diameter and a 1-inch outside diameter, with an overall length of 0.5 inches. Manufactured from hardened steel with a Rockwell hardness of 60 to 65 HRC, it delivers consistent bore alignment and resistance to wear under repeated drilling cycles. Machinists, tool-and-die makers, and production technicians install this type of bushing where accurate, repeatable hole location is required.

This bushing is suited for use in drill jigs and production fixtures across light manufacturing, metalworking, and machine shop environments. The headless design allows the bushing to sit flush within the jig plate, making it appropriate where a protruding flange would interfere with the workpiece or adjacent tooling. The press fit installation method ensures the bushing is retained securely in the jig body without additional fasteners. It conforms to ANSI standards for drill bushing geometry and tolerances.

Key Features

• Press fit installation — no fasteners required for retention in the jig plate
• Headless design sits flush with the jig plate surface for unobstructed workpiece contact
• 0.75-inch ID with a tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Hardened steel construction at 60 to 65 HRC for long service life under repeated drilling cycles
• Meets ANSI standards for drill bushing dimensions and tolerances
• Industry Code P for straightforward cross-referencing and replacement

Compatibility

Designed as an ANSI-standard Industry Code P press fit headless drill bushing, suitable for use in drill jigs and fixtures that accept a 1-inch outside diameter press fit bushing with a 0.75-inch bore.

Installation Notes

Installation is performed by pressing the bushing into a precisely reamed or bored hole in the jig plate using an arbor press or hydraulic press — never drive with a hammer directly on the bushing bore. Ensure the receiving hole diameter and finish match the press fit tolerance requirements before installation. Power down all machinery and secure the workpiece before servicing or replacing bushings in an active fixture. Removal typically requires a bushing driver or extraction tool to avoid damaging the jig plate bore.
