Boneham AM00000712 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000712 is a press fit headless drill bushing classified under industry code PM. It is designed to guide drill bits and other cutting tools with precision during machining and fabrication operations. The bushing is manufactured from steel for durability under repeated tool contact. With an inside diameter of 8.6 inches, a body outside diameter of 15.00 millimeters, and an overall length of 20.00 millimeters, this headless style bushing seats flush with the jig plate surface without an exposed flange. It is installed by pressing directly into a drill jig or fixture and is not renewable once installed.

This bushing is suited for use in production drilling, reaming, and boring applications where a low-profile, permanent guide is required. Typical installation scenarios include metal fabrication shops, toolroom work, and assembly jig construction. The headless design keeps the bushing below or flush with the jig surface, making it appropriate for close-clearance work where a flanged bushing would interfere with the workpiece or tooling setup.

Key Features

• Press fit installation method - no threads or retaining hardware required
• Headless PM-code design seats flush with the jig plate surface
• Steel construction for wear resistance under repeated tooling contact
• Inside diameter of 8.6 inches for precise tool guidance
• Non-renewable design provides a permanent, stable fit in the bushing plate
• Weighs 0.5 pounds - compact and easy to handle during fixture assembly

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing conforming to PM industry standards for use in standard drill jig and fixture plates.

Installation Notes

Installation is performed by qualified toolmakers or machinists using an arbor press or hydraulic press to seat the bushing into a properly reamed hole in the jig plate. The receiving hole must be machined to the correct interference fit tolerance before pressing to avoid damage to the bushing or plate. Do not hammer the bushing directly without a proper press fixture, as this can distort the bore. Once pressed in, the bushing is considered permanent and is not intended for removal and reuse.
