Boneham AM00000448 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000448 is a press fit headless drill bushing manufactured from steel and classified under industry code PM. It is designed to guide drill bits and other cutting tools with precision during machining operations, providing a hardened, wear-resistant bore that maintains accurate hole location over repeated use. With an inside diameter of 16.5 inches, a body outside diameter of 26.00 mm, and an overall bushing length of 16.00 mm, this bushing is installed directly into a jig plate or fixture by pressing it into a prepared hole without the use of a head flange. It is a non-renewable type, intended for permanent installation in the workholding fixture.

This bushing is suited for use in drill jigs, fixtures, and tooling plates across metalworking and fabrication environments. The headless press fit design keeps the bushing flush with the jig plate surface, making it appropriate for close-tolerance applications where a flanged head would interfere with the workpiece or adjacent hardware. Machinists, toolmakers, and fixture builders typically specify this style when building production jigs for repetitive drilling operations in both job shop and manufacturing settings.

Key Features

• Press fit installation method for permanent, secure seating in the jig plate
• Headless design sits flush with the fixture surface, eliminating flange interference
• Steel construction provides hardness and wear resistance for extended tool guidance life
• PM industry code classification for straightforward cross-reference and replacement sourcing
• Non-renewable type intended for fixed, long-term installation

Compatibility

Designed as an OEM-style replacement or new-build component for press fit headless drill bushing applications conforming to PM industry code specifications in standard drill jig and fixture assemblies.

Installation Notes

Press fit bushings are typically installed by toolmakers or machinist tradespeople using an arbor press or hydraulic press to seat the bushing squarely and fully into the prepared bore of the jig plate. The receiving hole must be machined to the correct interference fit tolerance before installation. Do not use a hammer directly on the bushing face, as this may damage the bore or cause misalignment. Once pressed in, this non-renewable bushing is not designed for removal and reinstallation.
