Boneham AM00000014 Drill Bushing Hm 11.2 Inch Id

Product Description

The BONEHAM AM00000014 is a press fit headless drill bushing manufactured to HM industry standards. It is designed to guide drill bits, reamers, and other cutting tools with precision during machining and fabrication operations. Made from steel, this bushing is pressed directly into a drill jig or fixture plate without a head flange, allowing it to sit flush with the plate surface. The inside diameter measures 11.2 inches, the body outside diameter measures approximately 18 millimeters (0.709 inches), and the overall bushing length is approximately 20 millimeters (0.787 inches). Machinists, toolmakers, and fixture builders install this component in production and job-shop environments where repeatable hole location accuracy is required.

This bushing is suited for use in drill jigs and fixture plates across general metalworking, tooling, and manufacturing applications. The headless press fit design makes it well-suited for applications where a flush plate surface is required and no removable or renewable bushing is needed. It is a non-renewable bushing, meaning it is intended to remain permanently installed in the fixture once pressed into place. Typical applications include production drilling, reaming, and countersinking operations in both light and heavy fabrication settings.

Key Features

• HM industry code designation for standardized sizing and interchangeability
• Press fit installation method for secure, permanent seating in jig plates
• Headless design allows flush mounting with the fixture plate surface
• Steel construction for durability and wear resistance under repeated tool cycling
• Non-renewable bushing intended for permanent fixture installation
• Inside diameter of 11.2 inches for precise tool guidance

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixture plates requiring an HM-coded press fit headless drill bushing with an 11.2-inch inside diameter.

Installation Notes

Installation is typically performed by a machinist or toolmaker using an arbor press or hydraulic press to seat the bushing flush and square in the prepared jig plate bore. The receiving bore in the fixture plate must be machined to the appropriate press fit tolerance before installation. Once pressed in, this bushing is not intended to be removed or replaced. Always verify bore dimensions and surface finish before pressing to prevent galling or misalignment.
