Boneham P648MH Press Fit Headless Drill Bushing

Product Description

The BONEHAM P648MH is a press fit headless drill bushing conforming to ANSI Industry Code P. It is designed to guide drill bits and other cutting tools with precision during machining and fabrication operations. The bushing features a 5/8 inch (0.6250 inch) inside diameter, a 1 inch outside diameter, and a 1/2 inch overall length. Manufactured from steel and hardened to 60 to 65 HRC, it delivers the wear resistance required for repeated tooling cycles. The inside diameter tolerance is held to +0.0001 to +0.0005 inches, ensuring accurate tool guidance. Machinists, tool-and-die workers, and maintenance technicians install these bushings in jig plates and fixture bodies.

This bushing is suited for use in drill jigs, fixture plates, and production tooling setups across general metalworking, tool-and-die, and MRO applications. The headless, press fit design seats flush within the jig plate, making it appropriate for applications where a protruding head would interfere with the workpiece or clamping setup. It is a non-renewable bushing, intended as a permanent installation once pressed into the receiving hole.

Key Features

• Press fit installation method for secure, permanent seating in jig plates
• Headless design sits flush with the jig plate surface
• Inside diameter: 0.6250 inches with tight tolerance of +0.0001 to +0.0005 inches
• Hardened steel construction at 60 to 65 HRC for high wear resistance
• Conforms to ANSI Industry Code P standards
• Non-renewable, permanent-style bushing

Compatibility

Designed as an ANSI Code P press fit headless drill bushing for use in standard drill jig plates and fixture bodies that accept a 1 inch outside diameter bushing bore.

Installation Notes

Installation is performed by pressing the bushing into a precision-bored receiving hole using an arbor press or hydraulic press. Power down all machinery and secure the workpiece or fixture before pressing the bushing into place. The receiving hole should be bored to the appropriate tolerance to achieve the interference fit required for a permanent installation. Because this is a non-renewable bushing, removal after installation is not recommended and may damage the jig plate.
