Boneham P568LR Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P568LR is a press fit headless drill bushing designed to guide cutting tools accurately during drilling, reaming, and boring operations. Manufactured from steel, this bushing features a 17/32-inch inside diameter, a 7/8-inch body outside diameter, and an overall length of 1/2 inch. The headless profile sits flush with the jig plate surface, making it well suited for applications where a protruding head would interfere with workpiece clearance or fixture travel. Machinists and toolmakers install this bushing in drill jig plates to maintain hole location accuracy across production runs.

This bushing is intended for use in fixed drill jig applications where the bushing is permanently pressed into the jig plate and not intended for removal or replacement during normal service. The press fit installation method ensures a secure, non-rotating fit within the jig body. Typical applications include production machining environments, toolroom fabrication, and custom fixture builds where repeatable hole location is critical.

Key Features

• Press fit installation method provides a secure, permanent seat in the jig plate
• Headless design sits flush with the plate surface for unobstructed workpiece handling
• 17/32-inch inside diameter with a close tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• 7/8-inch body outside diameter and 1/2-inch overall length for compact jig plate integration
• Steel construction for durability under repeated drilling cycles
• Non-renewable bushing — designed for permanent installation, not in-service replacement

Compatibility

Designed as an OEM-style fixed drill bushing for use in drill jig plates requiring a headless, press fit bushing with a P industry code designation.

Installation Notes

Installation is performed by machinists or toolmakers using a press or arbor press to seat the bushing flush into a properly reamed jig plate bore. Power down and secure all machinery before installing or inspecting jig components. Avoid driving the bushing with impact tools, as this can damage the bore tolerance or distort the bushing body. Verify the jig plate bore diameter matches the specified press fit tolerance before installation.
