Boneham AM00000254 Drill Bushing Hm 7.2 in Id

Product Description

The BONEHAM AM00000254 is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. Carrying the HM industry code, this bushing features a 7.2-inch inside diameter and a steel body construction that resists wear and deformation under repeated drilling operations. It installs without a head flange, seating flush within the jig plate for applications where a low-profile installation is required. Machinists, toolmakers, and production shop technicians install this bushing as part of drill jig setups to maintain accurate hole location across multiple workpieces. The part weighs 0.37 pounds.

This drill bushing is suited for use in fixed drill jig assemblies in both job-shop and production environments. Its press fit installation method locks it permanently into the jig plate, making it appropriate for high-volume applications where the bushing does not need to be replaced between runs. The HM designation identifies the body outside diameter and length in accordance with standard drill bushing industry classifications, allowing direct cross-reference when replacing worn bushings in existing jig tooling.

Key Features

• HM industry code classification for standard cross-reference compatibility
• Press fit installation method for permanent, fixed seating in jig plates
• Headless design allows flush mounting in applications with height or clearance restrictions
• Steel body construction provides wear resistance under continuous drill guidance loads
• Non-renewable design suitable for permanent jig configurations

Compatibility

Designed as an OEM-style replacement or new-build component for drill jig and fixture assemblies requiring an HM-coded press fit headless bushing with a 7.2-inch inside diameter.

Installation Notes

Press fit drill bushings are typically installed by toolmakers or machinist personnel using an arbor press to seat the bushing flush and square within the jig plate bore. The receiving bore must be machined to the appropriate interference fit tolerance before installation. Once pressed in, the bushing is not intended for removal without damaging the jig plate. Always verify bore alignment before pressing to final depth.
