Boneham P488LA Press Fit Headless Drill Bushing

Product Description

The BONEHAM P488LA is a press fit headless drill bushing designed to guide cutting tools with precision in metalworking and fabrication applications. With an inside diameter of 15/32 inches and a body outside diameter of 3/4 inches, this Type P bushing installs flush with the jig plate surface and requires no fasteners or locking rings to retain. The overall bushing length is 1/2 inch. Constructed from steel with an inside diameter tolerance of +0.0001 to +0.0005 inches, the P488LA provides the tight guidance required for consistent hole location in production drilling operations. Machinists, tool and die makers, and jig builders are the typical installers of this component.

This bushing is suited for use in drill jigs and fixtures where a permanent, headless installation is required. The press fit design means the bushing is driven or pressed directly into a reamed hole in the jig body, seating flush with the surface to allow unobstructed drill travel. It is commonly specified for production runs where repeatable hole placement across multiple workpieces is critical. The Type P industry code classifies it within the standard fixed drill bushing family, making it a recognized size in toolroom and production environments.

Installation Notes

Installation is performed by machinists or tool and die professionals. The receiving hole in the jig plate must be precision-reamed to the correct interference fit dimension before pressing the bushing into place. Use an arbor press or hydraulic press to seat the bushing - do not hammer directly on the bushing face. Once pressed in, the bushing is considered permanent and is not renewable or removable without rework of the jig body.
