Boneham P4016JN Press Fit Headless Drill Bushing

Product Description

The BONEHAM P4016JN is a press fit headless drill bushing used to guide drill bits and cutting tools with precision in jig and fixture applications. Classified as a P-type bushing per industry standards, it features an inside diameter of 0.368 inches with a tight tolerance of +0.0001 to +0.0005 inches, ensuring consistent hole location and repeatability across production runs. The body outside diameter measures 5/8 inches with an overall length of 1 inch. Constructed from steel, this bushing is designed for permanent installation in drill jigs and is not intended to be removed or replaced during service life. It is installed and serviced by machinists, toolmakers, and precision fabricators.

The P4016JN is suited for use in production drilling operations where a fixed, non-renewable bushing is required. It fits into a prepared jig plate bore and is pressed in place to maintain exact tool guidance throughout the run. Typical applications include drilling, reaming, and light boring operations in metalworking environments where repeatability and positional accuracy are critical. This bushing is appropriate for both short-run prototype fixtures and high-volume production tooling.

Key Features

• P-type headless design for permanent press fit installation in jig plates
• Inside diameter of 0.368 inches with tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Body outside diameter of 5/8 inches and overall length of 1 inch
• Steel construction for durability in repeated drilling operations
• Non-renewable design — intended as a fixed, permanent bushing
• Not counterbored — standard straight-body profile

Compatibility

Designed as an OEM-style press fit headless drill bushing for use in standard jig and fixture plates requiring a P-type bushing with a 5/8 inch body outside diameter.

Installation Notes

Installation is performed by qualified machinists or toolmakers using an arbor press or hydraulic press to seat the bushing flush into a precision-bored jig plate hole. The bore in the jig plate must be machined to the appropriate interference fit tolerance to ensure the bushing is retained without adhesive. Do not hammer the bushing in place with impact tools, as this may damage the bore or alter the inside diameter tolerance. Once pressed in, this bushing is not designed for removal or reuse.
