Boneham P486JY Press Fit Headless Drill Bushing

Product Description

The BONEHAM P486JY is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. Classified under industry code P, this bushing features a 25/64 inch inside diameter and a 3/4 inch outside diameter, with an overall length of 3/8 inch. Constructed from steel, it is pressed directly into a jig plate without a locking head, keeping the top surface flush. Machinists, tool and die makers, and precision fabricators rely on this type of bushing to maintain hole location accuracy across repeated drilling operations.

This bushing suits production drilling setups where a clean, flush-mounted guide is required. Its headless design is appropriate for jig plates where a protruding flange would interfere with workpiece seating or fixturing. The P486JY is a non-renewable style, meaning it is intended for permanent installation into the jig plate. It is well-suited for light to medium-duty drilling applications in metalworking, manufacturing, and precision assembly environments.

Key Features

• Press fit installation - no additional fasteners or locking hardware required
• Headless design provides a flush top surface for unobstructed workpiece contact
• 25/64 inch ID with a tight inside diameter tolerance of +0.0001 to +0.0005 inches for accurate tool guidance
• 3/4 inch OD and 3/8 inch overall length suit standard jig plate thicknesses
• Steel construction provides durability and wear resistance in repetitive drilling operations
• Non-renewable, permanent-fit configuration for stable long-term fixture use

Compatibility

Designed as an OEM-style press fit headless drill bushing conforming to industry code P, suitable for use in standard drill jig plates and fixtures requiring a permanent, flush-mounted bushing.

Installation Notes

Installation is performed by a machinist or toolmaker using a press - do not hammer the bushing in, as this can damage the bore or distort the OD fit. The jig plate bore must be machined to the correct interference fit specification before pressing. Once installed, this bushing is not designed for removal and replacement. Verify inside diameter clearance against the drill or reamer being guided before pressing the bushing into the plate.
