Boneham AM00000643 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000643 is a press fit headless drill bushing manufactured from steel and designated under industry code PM. This bushing is designed to guide drill bits with precision during machining and fabrication operations, maintaining accurate hole location and reducing tool deflection. It installs without a head, sitting flush within the drill jig plate for low-profile tooling setups. With an inside diameter of 6.25 inches, a body outside diameter of 12.00 millimeters, and an overall length of 20.00 millimeters, it suits jig and fixture work where consistent bore alignment is critical. Machinists, toolmakers, and production floor technicians are the primary installers.

This bushing is used in drill jigs and fixture plates across general metalworking, precision machining, and fabrication environments. The headless press fit design makes it well suited for applications where the bushing must sit flush with the jig plate surface, eliminating interference from a protruding flange. It is appropriate for both bench and machine-mounted jig assemblies in light to moderate production settings where repeatable hole location is required.

Key Features

• Press fit installation method for secure, tool-free retention in jig plate bores
• Headless design allows flush mounting within the fixture surface
• Steel construction provides durability and wear resistance under repeated tooling use
• Inside diameter of 6.25 inches for precise drill guidance
• Body outside diameter of 12.00 millimeters for standard jig plate fitment
• Overall bushing length of 20.00 millimeters suits typical plate thicknesses

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixture plates requiring a PM-coded press fit headless drill bushing.

Installation Notes

Installation is performed by toolmakers or machinists using a press or arbor press to seat the bushing flush into a prepared bore in the jig plate. Ensure the receiving bore is machined to the correct interference fit tolerance before pressing to avoid bushing damage or misalignment. De-energize and secure any power equipment associated with the jig fixture before performing bushing replacement. Do not hammer the bushing directly without a proper driver to avoid deforming the bore or bushing body.
