Boneham AM00000015 Drill Bushing Hm 11.2 Inch Id

Product Description

The BONEHAM AM00000015 is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in production and tooling applications. Classified under industry code HM, this bushing features an inside diameter of 11.2 inches and a body outside diameter of 18.00 millimeters, with an overall length of 25.00 millimeters. Manufactured from steel and heat-treated to a hardness of 60 to 65 HRC, it delivers the wear resistance needed for repetitive drilling operations. The inside diameter tolerance of +0.006/+0.017 mm ensures consistent tool guidance across high-volume work. This part is installed by machinists, toolmakers, and precision metalworking professionals.

This drill bushing is suited for use in drill jigs, fixture plates, and production tooling setups where a headless, press fit design is required. The HM classification indicates a headless style bushing intended to be pressed permanently into a drill plate or jig body without a locking collar. It is appropriate for applications where the bushing must sit flush with or below the jig surface. Typical use cases include production machining environments in automotive, aerospace, and general metalworking shops.

Key Features

• Press fit installation method for permanent, secure seating in jig plates
• HM industry code headless design sits flush with jig body surface
• Steel construction heat-treated to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.006/+0.017 mm for consistent tool guidance
• Meets ANSI standards for drill bushing geometry and fit
• Non-renewable design suited for long-run production tooling

Compatibility

Designed as an OEM-style replacement or original-fit component for drill jigs and fixture plates requiring a headless, press fit HM-style bushing with an 11.2-inch inside diameter.

Installation Notes

Press fit bushings are typically installed by a toolmaker or machinist using an arbor press to seat the bushing flush and square into a precision-bored hole in the jig plate. Power down all machinery and secure the workpiece fixture before installation or removal. Bore the receiving hole to the appropriate tolerance to achieve proper interference fit per ANSI standards. Do not hammer the bushing directly without a driver to avoid distorting the bore.
