Boneham P486JE Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P486JE is a press fit headless drill bushing used to guide drill bits and cutting tools with precision in jig and fixture applications. With an inside diameter of 0.348 inches (Letter Size S) and a body outside diameter of 3/4 inch, this bushing presses directly into a drill jig plate without the need for a retaining head. The overall length is 3/8 inch. Constructed from hardened steel at 60 to 65 HRC, it provides durable, wear-resistant tool guidance for repetitive drilling operations. Machinists, toolmakers, and precision fabricators install this type of bushing during fixture builds and production runs.

This bushing is suited for use in drill jigs and fixtures in production machining environments where consistent hole location is required. The press fit installation method seats the bushing permanently into the jig body, making it appropriate for fixed setups that do not require bushing removal between operations. It is a non-renewable design and is not counterbored. ANSI standards apply to this bushing, making it interchangeable with other ANSI-conforming P-series headless press fit drill bushings of the same dimensional spec.

Key Features

• Press fit installation — no head, seats flush with or below jig plate surface
• Inside diameter of 0.348 inches (Letter Size S) with a close-tolerance bore: +0.0001 to +0.0005 inches
• Body outside diameter of 3/4 inch, overall length of 3/8 inch
• Hardened steel construction at 60 to 65 HRC for extended wear life in high-cycle drilling
• ANSI-compliant P-series design for standardized jig and fixture compatibility
• Non-renewable, non-counterbored configuration for permanent fixture installations

Compatibility

Designed as an ANSI-compliant P-series press fit headless drill bushing for use in drill jigs and fixtures requiring a 0.348-inch bore, 3/4-inch OD, and 3/8-inch overall length.

Installation Notes

This bushing is installed by toolmakers or machinists using a press or arbor press to seat it into a prepared jig plate bore. Power down all associated machinery before working on any fixture. Ensure the receiving bore in the jig plate is machined to the correct tolerance for a proper press fit interference. Do not hammer the bushing in freehand, as this can damage the bore or misalign the bushing.
