Boneham AM00000223 Drill Bushing Hm 6.3 Inch Id

Product Description

The BONEHAM AM00000223 is a press fit headless drill bushing manufactured to HM industry code standards. It is designed to guide drill bits, reamers, and other cutting tools with precision during machining and fabrication operations. Made from hardened steel with a surface hardness of 60 to 65 HRC, this bushing resists wear under repeated tool contact. The 6.3 inch inside diameter and 12.00 mm body outside diameter provide a defined tool path in jig and fixture applications. Machinists, toolmakers, and precision fabricators install these bushings in drill jigs to maintain positional accuracy across production runs.

This bushing is suited for use in drill jig assemblies in machine shops, metalworking facilities, and manufacturing environments. The headless, press fit design allows it to be seated flush within a jig plate without a flange protruding above the surface. This makes it appropriate for applications where tool clearance above the jig plate is limited or where a smooth upper surface is required. It is not a renewable bushing, meaning it is intended for permanent installation in the jig plate rather than periodic replacement during a run.

Key Features

• HM industry code classification for standardized jig and fixture compatibility
• Press fit installation method for secure, permanent seating in jig plates
• Hardened steel construction with 60 to 65 HRC surface hardness for long tool life
• Inside diameter tolerance of +0.005/+0.014 mm for precise tool guidance
• Headless, flush-mount profile for applications requiring unobstructed jig plate surface
• Meets ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed as an OEM-style replacement or new-installation component for standard drill jig and fixture assemblies requiring an HM-code press fit headless bushing with a 6.3 inch inside diameter.

Installation Notes

Installation is performed by toolmakers or machinists using a press or arbor press to seat the bushing flush in the jig plate bore. The jig plate bore must be machined to the correct interference fit tolerance before pressing to avoid bushing damage or improper seating. Do not hammer the bushing directly without a proper driver, as this can damage the bore or distort the bushing. Power down any associated machinery before servicing or replacing jig components.
