Boneham P105AY Press Fit Headless Drill Bushing

Product Description

The BONEHAM P105AY is a press fit headless drill bushing engineered for precision hole-guiding applications in metalworking and machining operations. Built from steel, this Type P bushing features an inside diameter of 0.041 inches (Wire Size 59) with a tight tolerance of +0.0001 to +0.0004 inches, a body outside diameter of 5/32 inches, and an overall length of 5/16 inches. The headless design allows flush installation in jig plates where a protruding head would interfere with workpiece seating or fixture clearance. Machinists and toolmakers rely on this style of bushing to guide drill bits, reamers, and other cutting tools with repeatable accuracy across production runs.

This bushing is intended for use in drill jigs and fixture plates in both production and toolroom environments. Its press fit installation method means it is driven or pressed directly into a prepared hole in the jig body without additional fasteners or locking hardware. The Type P classification and industry-standard dimensions make it a direct fit in applications that call for a permanent, non-renewable liner bushing. Typical users include machinists, tool and die makers, and fixture builders working in job shops or manufacturing facilities.

Key Features

• Press fit installation — no locking hardware required for secure seating in jig plate
• Headless design allows flush mounting where head clearance is restricted
• Inside diameter tolerance of +0.0001 to +0.0004 inches for consistent drill guidance
• Steel construction provides durability under repeated drilling cycles
• Type P industry code ensures interchangeability with standard jig bushing specifications
• Non-renewable (permanent) design suited for fixed, high-repeat drilling locations

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jig fixtures requiring a Type P press fit headless bushing with a 0.041-inch inside diameter and 5/32-inch outside diameter.

Installation Notes

Installation is typically performed by a machinist or toolmaker using an arbor press or similar controlled-force pressing equipment to seat the bushing flush in a properly toleranced jig plate bore. The receiving hole in the jig plate must be machined to the correct interference fit per the bushing outside diameter tolerance before installation. Once pressed in, this non-renewable bushing is not designed for removal and reinstallation. Always verify bore preparation and bushing alignment before applying press force to avoid damage to the bushing or jig body.
