Boneham AM00000197 Drill Bushing Hm 5.75 in Id

Product Description

The BONEHAM AM00000197 is a press fit headless drill bushing conforming to the HM industry code designation. This bushing is manufactured from hardened steel and is designed to guide drill bits, reamers, and other cutting tools with precision during machining and fabrication operations. It installs without a head flange, seating flush within the jig plate for applications where a low-profile installation is required. The inside diameter measures 5.75 inches with a tolerance of +0.004/+0.012 mm, and hardness is rated at 60 to 65 HRC for extended wear resistance. Machinists, toolmakers, and fixture builders are the primary installers of this component.

This drill bushing is suited for use in drill jigs, fixture plates, and tooling setups in industrial manufacturing, metalworking shops, and precision machining environments. The headless press fit design makes it appropriate for jig applications where the bushing must sit flush with the work surface and remain permanently fixed without a locking collar. It is a non-renewable bushing, meaning it is intended for permanent installation rather than field replacement under normal service conditions. Compliance with ANSI standards applies to this component.

Key Features

• HM industry code designation for standardized drill jig bushing compatibility
• Press fit installation method for permanent, secure seating in jig plates
• Hardened steel construction rated at 60 to 65 HRC for wear resistance
• Inside diameter tolerance of +0.004/+0.012 mm for precise tool guidance
• Headless design provides flush, low-profile installation
• Meets ANSI standards for drill bushing dimensional conformance

Compatibility

Designed as an OEM-style replacement or new-installation component for ANSI-compliant HM-series press fit drill jig bushing applications in standard fixture plates.

Installation Notes

Installation is performed by toolmakers or machinist trades using a press or arbor press to seat the bushing into a precision-bored hole in the jig plate. Ensure the receiving bore is machined to the correct interference fit tolerance before pressing to avoid bushing damage or bore distortion. This is a non-renewable bushing and is not designed for removal and reinstallation once pressed in. Follow applicable ANSI B94.33 guidelines for drill bushing installation and jig design.
