Boneham P486LR Press Fit Headless Drill Bushing

Product Description

The BONEHAM P486LR is a press fit headless drill bushing designed to guide cutting tools accurately during drilling, reaming, and related machining operations. It carries a 17/32 inch inside diameter and a 3/4 inch body outside diameter, with an overall length of 3/8 inch. Manufactured from steel and hardened to 60 to 65 HRC, this bushing provides the wear resistance and dimensional stability required in production jig and fixture work. The headless design sits flush with the jig plate surface, making it well suited for close-tolerance applications where a head would interfere with the workpiece or fixture setup.

This bushing is used in drill jigs and tooling fixtures in metalworking and manufacturing environments. It is appropriate for production runs where consistent hole location is critical. The press fit installation method locks the bushing permanently into the jig body, making it a non-renewable fixed liner. Machinists, tool and die makers, and jig and fixture builders install this type of component during fixture fabrication or scheduled tooling replacement.

Key Features

• 17/32 inch inside diameter with a tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• 3/4 inch body outside diameter and 3/8 inch overall length for compact jig plate integration
• Hardened steel construction at 60 to 65 HRC for extended wear life in high-cycle applications
• Headless design allows flush seating in the jig plate without surface protrusion
• Press fit installation method provides a permanent, non-renewable fit in the jig body
• Conforms to ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed as an OEM-style fixed liner for drill jigs and tooling fixtures requiring a press fit headless bushing with a P industry code designation per ANSI standards.

Installation Notes

Installation is performed by tool and die makers or machining professionals using an arbor press or hydraulic press to seat the bushing flush into the prepared jig plate bore. The receiving bore must be machined to the correct press fit tolerance before installation, as the bushing is non-renewable once pressed in. Power down and lock out any associated machine before performing fixture maintenance or bushing replacement. Do not use impact tools to drive the bushing, as this can damage the bore or distort the bushing geometry.
