Boneham AM00000190 Press Fit Headless Drill Bushing Hm

Product Description

The BONEHAM AM00000190 is a press fit headless drill bushing in the HM industry classification, designed to guide drill bits and other cutting tools with precision during machining operations. Manufactured from steel, this bushing is pressed directly into a jig plate without a head or flange, providing a flush, low-profile installation. It features an inside diameter of 5.4 inches, a body outside diameter of 10.00 mm, and an overall length of 20.00 mm. Machinists, toolmakers, and production shop technicians use this part to maintain accurate hole location and tool alignment across repeated drilling cycles.

This headless press fit bushing is suited for fixed drilling applications where the bushing remains in place for the full production run. It is a non-renewable style, meaning it is intended to be permanently installed in the drill jig rather than swapped out between operations. Typical use cases include production jigs, fixture plates, and tooling setups in metal fabrication, aerospace component manufacturing, and general machining environments where consistent hole positioning is critical.

Key Features

• HM industry code classification for standard headless press fit bushing sizing
• 5.4-inch inside diameter provides tool guidance for large-diameter drilling operations
• Steel construction for durability and resistance to wear during high-cycle use
• Headless design installs flush with the jig plate surface for low-profile clearance
• Non-renewable configuration suited for permanent, fixed-location tooling setups
• Weighs 0.25 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement or original installation bushing for drill jig plates and fixture tooling that accept HM-series press fit headless bushings with a 5.4-inch inside diameter.

Installation Notes

Installation of press fit drill bushings is typically performed by toolmakers or machinist personnel using an arbor press or hydraulic press to drive the bushing squarely into the prepared jig plate bore. The receiving hole should be machined to the appropriate interference fit tolerance for the bushing outside diameter before pressing. Power down any associated equipment and secure the workpiece before pressing the bushing into place. Do not hammer the bushing directly, as this can damage the bore or misalign the bushing in the plate.
