Boneham P4816LK Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P4816LK is a headless, press fit drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to Industry Code P, this bushing features a 0.5-inch inside diameter, 0.75-inch body outside diameter, and a 1-inch overall length. Manufactured from steel hardened to 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling operations. The press fit design locks the bushing permanently into the jig plate without a locking collar. It is a non-renewable type, intended for permanent installation. Machinists and toolmakers working in production or job-shop environments install this component as part of drill jig assemblies.

This bushing is suited for use in drill jigs, fixtures, and tooling plates where a permanent, flush-mounted guide bushing is required. The headless profile sits flush with or below the jig plate surface, making it appropriate for applications where a protruding head would interfere with workpiece clamping or part clearance. Typical installations are found in metalworking production environments, aerospace tooling, and general machining operations requiring repeatable hole location accuracy.

Key Features

• Industry Code P headless press fit design for permanent jig installation
• 0.5-inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for accurate tool guidance
• 0.75-inch body outside diameter and 1-inch overall length
• Steel construction hardened to 60 to 65 HRC for extended wear life
• No locking collar required — installs directly into the jig plate bore
• Meets ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed as an OEM-style replacement or new-installation component for ANSI-standard drill jig assemblies requiring an Industry Code P headless press fit bushing with a 0.5-inch bore.

Installation Notes

Press fit bushings are installed by a machinist or toolmaker using an arbor press or hydraulic press — never hammer directly on the bushing face. The receiving bore in the jig plate must be machined to the mating tolerance for a Code P press fit bushing. Verify bore cleanliness and alignment before pressing. Once installed, this is a non-renewable bushing and is not intended for removal and reuse.
