Boneham P648MP Press Fit Headless Drill Bushing

Product Description

The BONEHAM P648MP is a headless, press fit drill bushing manufactured from steel and used to guide drill bits with precision during machining and fabrication operations. With an inside diameter of 43/64 inches and a body outside diameter of 1 inch, this P-series bushing seats flush into a jig plate with no protruding head, keeping the work surface clear. The overall length is 1/2 inch. It is a non-renewable bushing, meaning it is permanently pressed into the jig rather than designed for field replacement. Machinists, toolmakers, and production fabricators install this component when setting up drill jigs for repeatable hole placement.

This bushing is suited for use in drill jig fixtures across general machining, metalworking, and production fabrication environments. The headless design makes it appropriate for applications where a flush mounting profile is required and the bushing will remain fixed for the life of the jig. The P-series industry code designation identifies the bushing type within standard tooling catalogs, allowing straightforward cross-referencing when building or repairing drill jig setups.

Key Features

• Press fit installation method for permanent, rigid seating in jig plate bores
• Headless design provides a flush, unobstructed work surface
• 43/64 inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for accurate drill guidance
• 1 inch body outside diameter for positive press fit retention
• Steel construction for durability in repetitive drilling operations
• Industry code P for straightforward catalog and cross-reference identification

Compatibility

Designed as an OEM-style press fit headless drill bushing for use in standard drill jig fixtures requiring a P-series bushing with a 43/64 inch inside diameter and 1 inch outside diameter.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing into the jig plate bore. The mating bore in the jig plate must be machined to the appropriate interference fit tolerance before pressing to avoid cracking or distorting the plate. Do not hammer the bushing in directly without a proper pressing tool, as this can damage the bushing bore or alter its roundness. Once pressed in, this bushing is not designed for removal and reuse.
