Boneham AM00000659 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000659 is a press fit headless drill bushing conforming to the PM industry code standard. It is designed to guide drill bits accurately and consistently during drilling operations, providing a hardened steel bore that resists wear over repeated use. With an inside diameter of 7.25 inches, this bushing is pressed directly into a jig plate or fixture without a head flange, creating a flush, low-profile installation. Machinists, toolmakers, and fixture builders install this type of component in production drilling jigs where hole-location repeatability is critical and vertical clearance above the workpiece is limited.

This bushing is suited for use in drill jig fixtures found in machine shops, manufacturing production lines, and tool rooms. The headless press fit design eliminates the need for a locking collar or shoulder, making it appropriate for thin jig plates where a flanged bushing would be impractical. Its steel construction withstands the heat and abrasion generated during high-cycle drilling. The PM designation identifies its dimensional series within standard drill bushing classification systems used across industrial tooling applications.

Key Features

• Press fit installation — no collar or locking mechanism required
• Headless design provides flush, low-profile seating in jig plates
• PM industry code conforms to standard drill bushing dimensional classification
• 7.25 inch inside diameter for consistent bit guidance
• Steel construction for wear resistance under high-cycle drilling conditions
• Non-renewable design — intended as a permanent press fit fixture component

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for standard PM-series press fit headless drill jig fixtures.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing into a properly toleranced hole in the jig plate. The receiving hole in the jig must be machined to the correct interference fit tolerance for press fit bushings per applicable tooling standards before installation. Inspect the bore and seating surface for burrs or debris prior to pressing. Once installed, the bushing is not intended to be removed and reused.
