Boneham AM00000483 Drill Bushing Pm 20.5 in Id Steel

Product Description

The BONEHAM AM00000483 is a press fit headless drill bushing with industry code PM, designed to guide drill bits and cutting tools with precision in metalworking and machining applications. Manufactured from steel, this bushing installs without a head flange, sitting flush within the jig plate for unobstructed tool travel. The inside diameter measures 20.5 inches, and the body outside diameter measures approximately 30.00 millimeters with an overall length of 36.00 millimeters. It is a non-renewable fixed bushing intended for permanent or long-service installations where the bushing is pressed directly into the drill jig or fixture body.

This bushing is suited for use in production drilling jigs and fixture plates across industrial machining environments. The headless PM-style configuration is common in applications where clearance above the jig plate surface is limited or where a smooth top surface is required. Licensed machinists, tool-and-die makers, and fixture builders are the primary trades that install and service this type of tooling component. It is appropriate for both prototype and high-volume production setups.

Key Features

• Press fit installation method - no retaining ring or locking mechanism required
• Headless PM-style profile sits flush with jig plate surface
• Steel construction for durability under repeated drilling cycles
• Non-renewable design intended for fixed, long-term installations
• Inside diameter of 20.5 inches ensures consistent tool guidance
• UNSPSC Code 31171603 for procurement classification

Compatibility

Designed as an OEM-style press fit headless drill bushing conforming to PM industry code standards, suitable for use in standard drill jig and fixture plates that accept press fit bushing installations of the corresponding outside diameter.

Installation Notes

Installation is performed by tool-and-die makers or machinist tradespeople using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. The receiving bore should be machined to the appropriate interference fit tolerance before pressing to avoid bushing damage or bore distortion. Do not hammer the bushing directly without a proper press driver. Confirm the bushing is fully seated and flush before placing the jig into service.
