Boneham AM00000236 Drill Bushing Hm 6.7 Inch Id

Product Description

The BONEHAM AM00000236 is a press fit headless drill bushing manufactured to HM industry code standards. It is designed to guide drill bits, reamers, and other cutting tools with precision during machining and fabrication operations. The bushing features a 6.7-inch inside diameter and a steel body, providing the hardness and wear resistance required in production drilling fixtures and jig plate applications. This type of bushing is installed without a locking collar or head flange, making it suitable for flush-mount applications where a low-profile installation is required. Machinists, tool-and-die makers, and precision fabricators install these components as part of drill jig assemblies.

This bushing is used in industrial machining environments where repeatable hole location accuracy is critical. It fits into drill jig plates and fixtures used across metal fabrication, aerospace component production, and general manufacturing. The headless press fit design allows the bushing to be driven flush into the jig plate bore, making it well suited for high-volume production drilling operations where clearance above the workpiece surface is limited. It is not a renewable bushing, meaning it is intended for permanent installation in the jig body.

Key Features

• HM industry code classification for standard headless press fit drill bushing dimensions
• 6.7-inch inside diameter for precise tool guidance
• Steel construction provides hardness and wear resistance in repetitive drilling applications
• Headless press fit design allows flush installation in jig plates
• Non-renewable fixed installation for permanent jig assemblies
• Compact body supports close-tolerance fixture layouts

Compatibility

Designed as an OEM-style replacement or original-equipment component for drill jig and fixture assemblies requiring an HM-code headless press fit drill bushing with a 6.7-inch inside diameter.

Installation Notes

Press fit drill bushings are installed by machinists or toolmakers using an arbor press or hydraulic press to drive the bushing into a precision-reamed bore in the jig plate. The bore in the jig plate must be machined to the correct interference fit tolerance for the bushing outside diameter before installation. Never hammer the bushing directly without a proper press arbor, as this can distort the bore geometry. Once pressed in, this bushing is not designed for removal and reuse.
