Boneham P324GW Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P324GW is a press fit headless drill bushing manufactured from steel and designed to guide cutting tools with precision during drilling operations. Assigned industry code P, this bushing features a 0.234 inch inside diameter with a tight inside diameter tolerance of plus 0.0001 to plus 0.0004 inches, ensuring accurate hole location and repeatable tool guidance. The outside diameter measures 0.5 inches and the overall length is 0.25 inches. It is installed by pressing directly into a jig plate or fixture body without a locking head, making it suited for applications where a flush or recessed installation is required. Licensed machinists, toolmakers, and fixture builders typically specify and install this component.

This bushing is used in drill jig fixtures for production machining environments where controlled hole placement is critical. The headless design makes it appropriate for installations where the bushing must sit flush with or below the fixture surface. Its compact 0.25 inch length suits thin jig plates. It is not renewable, meaning it is pressed in permanently and is not intended for field replacement without re-pressing. Typical applications include metalworking production jigs in both light industrial and precision machining settings.

Key Features

• Press fit installation method seats the bushing permanently into a jig plate without fasteners or locking collars
• Headless design allows flush or sub-flush mounting in fixture bodies
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches provides precise tool guidance
• Steel construction offers durability and wear resistance under repeated drilling cycles
• Compact 0.25 inch overall length suits thin or space-constrained fixture plates
• Industry code P designation for straightforward cross-reference with standard bushing catalogs

Compatibility

Designed as an OEM-style press fit headless drill bushing for use in standard drill jig fixtures requiring a 0.5 inch outside diameter press fit seat and a 0.234 inch inside diameter tool guide bore.

Installation Notes

Installation is performed by toolmakers or fixture builders using a press to drive the bushing flush into a properly sized receiver hole in the jig plate. The receiver hole should be machined to the appropriate interference fit tolerance before pressing to avoid deformation of the bushing bore. Because the bushing is non-renewable, the jig plate must be replaced or re-bored if the bushing needs removal. Follow applicable shop safety practices and ensure the press is aligned with the bushing axis before applying force.
