Boneham P568LK Press Fit Headless Drill Bushing

Product Description

The BONEHAM P568LK is a press fit headless drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. 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. With a 0.5 inch inside diameter and 0.875 inch outside diameter, it installs flush with the jig plate surface, leaving no protruding head to interfere with workpiece positioning. The 0.5 inch overall length suits compact fixture designs. This is a non-renewable, permanent-installation bushing conforming to ANSI standards.

This bushing is used in machining and fabrication environments where repeatable hole location accuracy is critical. It seats permanently into a jig plate or fixture body via press fit, making it appropriate for high-volume production runs where the bushing position is fixed for the life of the tooling. Typical applications include drill jigs, assembly fixtures, and inspection fixtures in metalworking shops, tool rooms, and manufacturing facilities. Installation is performed by toolmakers, machinists, and fixture builders working to ANSI-compliant tooling standards.

Key Features

• Hardened steel construction at 60 to 65 HRC for extended wear life under repeated tool contact
• Press fit installation method provides a permanent, non-renewable mount in the jig plate
• Headless design sits flush with the fixture surface, eliminating interference with workpieces
• Inside diameter tolerance of +0.0001 to +0.0005 inches ensures close tool guidance
• Conforms to ANSI standards for industry-compatible fitment
• Bushing Industry Code P for straightforward replacement and cross-referencing

Compatibility

Designed as an ANSI-standard press fit headless drill bushing suitable for jig plates and fixtures bored to accept a 0.875 inch outside diameter press fit bushing seat.

Installation Notes

Press fit bushings are installed by toolmakers or machinists using an arbor press or hydraulic press. The receiving bore in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing is considered permanent and is not designed for removal or replacement in service. Always verify bore dimensions with gauging before pressing the bushing into the fixture to avoid damage to the plate or bushing.
