Boneham P168CY Press Fit Headless Drill Bushing

Product Description

The BONEHAM P168CY is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision in jig and fixture applications. Built to Industry Code P standards, this bushing features a 0.098 inch inside diameter, a 1/4 inch body outside diameter, and a 1/2 inch overall length. Constructed from steel hardened to 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling operations. The inside diameter is held to a tight tolerance of +0.0001 to +0.0004 inches, ensuring consistent hole location and minimal tool runout across production runs.

This bushing is suited for use in drill jigs, tooling plates, and fixture assemblies found in machine shops, fabrication facilities, and manufacturing environments. The headless design allows the bushing to sit flush within the jig body, making it appropriate for applications where a protruding flange would interfere with workpiece clearance or clamping. It is installed permanently by press fitting into a prepared bore and is classified as non-renewable. Machinists, tool and die makers, and fixture builders are the primary installers.

Key Features

• Inside diameter of 0.098 inches (wire size 40) with tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for extended wear life in high-cycle drilling applications
• Press fit installation method for permanent, secure seating in jig bodies and tooling plates
• Headless design allows flush installation where flange clearance is a constraint
• Meets ANSI standards for drill bushing dimensional and performance requirements
• Bushing Industry Code P for straightforward cross-reference and replacement identification

Compatibility

Designed as an OEM-style replacement or original-fit drill bushing for standard ANSI-compliant jig and fixture assemblies requiring a press fit headless bushing with a 0.098 inch inside diameter and 1/4 inch outside diameter.

Installation Notes

Installation is performed by machinists or tool and die makers using an arbor press or hydraulic press to seat the bushing into a precision-bored hole in the jig body. The receiving bore must be machined to the appropriate interference fit tolerance before installation. Do not use a hammer directly on the bushing face, as this can distort the inside diameter and compromise tool guidance accuracy. Once pressed in, this bushing is not designed for removal and reuse.
