Boneham AM00000568 Drill Bushing Pm 4.6 Inch Id

Product Description

The BONEHAM AM00000568 is a press fit headless drill bushing with industry code PM, designed to guide drill bits with precision in metal fabrication, tooling, and machining applications. With an inside diameter of 4.6 inches, a body outside diameter of 7.00 mm, and an overall bushing length of 16.00 mm, this bushing installs directly into a jig plate without a head flange, creating a flush, clean surface. Constructed from steel, it provides durable wear resistance in high-cycle drilling operations. Machinists, toolmakers, and jig-and-fixture builders install this type of bushing in production and maintenance environments where repeatable hole location is required.

This bushing is suited for use in drill jigs and fixture plates where a headless profile is needed to avoid interference with workpiece clamping or seating. The PM industry code designates a press fit installation method, meaning the bushing is pressed directly into a reamed hole in the jig plate and is not intended to be removed and replaced in service. It is appropriate for applications requiring a permanent bushing installation in steel or hardened jig bodies.

Key Features

• Press fit installation for permanent, secure seating in jig plates
• Headless design provides a flush surface that does not interfere with workpiece contact
• PM industry code designation for standardized fitment and interchangeability
• Steel construction for wear resistance in high-cycle drilling operations
• Inside diameter of 4.6 inches for precise drill bit guidance
• Body outside diameter of 7.00 mm and overall length of 16.00 mm for compact installation footprint

Compatibility

Designed as a PM-code press fit headless drill bushing for use in standard drill jig plates and fixture tooling that accept press fit bushing installations.

Installation Notes

Installation is performed by toolmakers or machinists using a bushing press or arbor press to drive the bushing into a precision-reamed hole in the jig plate. The receiving hole must be reamed to the correct interference fit tolerance before installation. Once pressed in, PM-type bushings are not designed for removal without risk of damage to the jig plate. Ensure all workholding fixtures are secured and the press is properly aligned before pressing to avoid bushing distortion or misalignment.
