Boneham P406JQ Press Fit Headless Drill Bushing 3/8in Id

Product Description

The BONEHAM P406JQ is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in metalworking and machining applications. Built to ANSI standards, this bushing features a 3/8-inch inside diameter and a 5/8-inch outside diameter with a 3/8-inch overall length. Constructed from steel hardened to 60-65 HRC, it delivers consistent dimensional stability under repeated use. The inside diameter tolerance of +0.0001 to +0.0005 inches ensures close control of tool alignment, making it a reliable choice for jig and fixture work where positional accuracy is critical.

This bushing is suited for press fit installation in drill jigs used across production machining, tool and die, and fabrication environments. The headless, non-renewable design makes it appropriate for permanent installations where the bushing is pressed directly into the jig plate and is not intended for field replacement. It carries Bushing Industry Code P, consistent with standard catalog tooling for shops sourcing to common jig-building specifications.

Key Features

• 3/8-inch inside diameter with tight tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• 5/8-inch body outside diameter for secure press fit retention in jig plate
• 3/8-inch overall length - compact profile for thin jig plate applications
• Steel construction hardened to 60-65 HRC for wear resistance under high-cycle use
• Headless, non-renewable design for permanent press fit installations
• Meets ANSI standards - compatible with standard jig bushing specifications

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixtures requiring a permanent press fit headless bushing with Bushing Industry Code P designation and ANSI-compliant dimensioning.

Installation Notes

Installation is performed by machinists or tool and die makers using a hydraulic or arbor press to seat the bushing flush in the prepared jig plate bore. Ensure the mating bore is machined to the correct interference fit tolerance before pressing. Do not hammer the bushing directly without a proper driver to avoid deformation of the bore or bushing face. Once pressed in, this bushing is not designed for removal or reuse.
