Boneham AM00000559 Drill Bushing Pm 4.3 in Id Steel

Product Description

The BONEHAM AM00000559 is a press fit headless drill bushing manufactured from steel and designed to guide drill bits with precision in jig and fixture applications. With an inside diameter of 4.3 inches and an overall bushing length of 16.00 millimeters, this bushing installs directly into a drill jig plate using an interference press fit, requiring no locking flange or liner bushing. It carries the industry designation PM, which identifies it as a headless, non-renewable style. Machinists and toolmakers rely on this type of bushing for high-volume production setups where permanent installation is acceptable and repeatable drill location accuracy is required.

This bushing is suited for use in drill jig plates in industrial machining and metalworking environments, including tool rooms and production machine shops. The press fit installation method makes it appropriate for permanent fixture builds where the bushing will not need to be replaced during the service life of the jig. It is typically installed by toolmakers or machinist-level trades using a hydraulic or arbor press to achieve proper seating without damage to the bore.

Key Features

• Steel construction for durability and wear resistance in drill guiding applications
• 4.3 inch inside diameter provides a precise guide bore for compatible drill bit sizes
• PM industry code designates headless, press fit style with no retaining flange
• Non-renewable design intended for permanent installation in drill jig plates
• Overall bushing length of 16.00 millimeters suits standard jig plate thicknesses

Compatibility

Designed as an OEM-style PM headless press fit drill bushing for use in drill jigs and fixtures requiring a permanently installed, unflanged guide bushing with a 4.3 inch inside diameter.

Installation Notes

Installation is performed by toolmakers or machinists using a hydraulic press or arbor press to drive the bushing into the prepared jig plate bore. The receiving bore should be machined to the appropriate interference fit tolerance before pressing. Never use a hammer directly on the bushing face, as this can damage the bore or distort the bushing. Verify drill bit clearance through the bushing ID before committing the fixture to production use.
