Boneham AM00000095 Drill Bushing Hm 21.5 Inch Id

Product Description

The BONEHAM AM00000095 is a press fit headless drill bushing with an HM industry code, designed for precision hole location and drill guidance in machining and fabrication applications. Built from steel, this bushing is pressed directly into a jig plate without a head flange, allowing it to sit flush with the work surface. The inside diameter measures 21.5 inches, with a body outside diameter of 30.00 millimeters and an overall bushing length of 20.00 millimeters. It is a non-renewable style, meaning it is permanently installed rather than designed for field replacement. Machinists and toolmakers install this type of bushing when a low-profile, fixed guide is required in a drill jig or fixture.

This bushing is suited for use in drill jig and fixture assemblies across metalworking, tool-and-die, and general machining environments. The press fit installation method makes it appropriate for applications where the bushing position must remain fixed under repeated drill cycles. The HM industry code designation follows standard drill bushing classifications used in production tooling. It is typically installed by toolmakers or machinists during jig fabrication or fixture setup.

Key Features

• HM industry code press fit headless design for flush, fixed installation in jig plates
• 21.5-inch inside diameter for precise drill guidance
• Steel construction for durability under repeated machining cycles
• Non-renewable configuration — permanently pressed into the jig plate
• Low-profile headless body sits flush with the work surface

Compatibility

Designed as an OEM-style replacement or new-installation component for standard drill jig and fixture assemblies requiring an HM-code press fit headless drill bushing.

Installation Notes

Installation is performed by toolmakers or machinists using a press or arbor press to seat the bushing flush into a prepared jig plate bore. The receiving bore should be machined to the appropriate tolerance for press fit retention before installation. Once pressed in, this non-renewable bushing is not intended for removal and reinstallation. Verify bore alignment and cleanliness before pressing to avoid damage to the bushing or jig plate.
