Boneham AM00000273 Press Fit Headless Drill Bushing Hm

Product Description

The BONEHAM AM00000273 is a press fit headless drill bushing in the HM industry classification, manufactured from steel for use in jig and fixture tooling applications. It installs without a head flange, seating flush or below the plate surface to guide drill bits and other cutting tools with precision. The bushing measures 7.7 inches inside diameter, with a body outside diameter of 12.00 millimeters and an overall length of 16.00 millimeters. Machinists, tool and die makers, and fixture builders install this component when consistent hole location accuracy is required across repeated operations.

This bushing is suited for production drilling, reaming, and boring setups where a renewable or removable bushing is not required. The headless design makes it appropriate for applications where surface clearance is limited or where the bushing must sit below the jig plate surface. It is pressed directly into the liner or jig plate bore. Typical applications include both small-batch and production machining environments in industrial manufacturing settings.

Key Features

• HM industry bushing classification for standardized fitment in drill jig systems
• Press fit installation method seats the bushing permanently in the liner bore
• Steel construction provides wear resistance under repeated tool guidance cycles
• Headless design allows flush or sub-surface mounting in jig plates
• Non-renewable fixed bushing eliminates the need for a locking mechanism

Compatibility

Designed as an OEM-style replacement or new-installation component for standard HM-series drill jig fixture plates requiring a press fit headless drill bushing.

Installation Notes

Installation is performed by machinists or toolmakers using a press or arbor press to drive the bushing into a properly sized liner or jig plate bore. The bore in the receiving plate must be machined to the correct interference fit tolerance before pressing to avoid bushing damage or misalignment. Power down any associated machine tooling before servicing or replacing jig components. This is a permanent installation — the bushing is not designed for field removal or replacement once pressed in place.
