Boneham P2622HJ Headless Drill Bushing 0.257 in Id Steel

Product Description

The BONEHAM P2622HJ is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built from steel, this bushing features a 0.257 inch inside diameter, a 13/32 inch body outside diameter, and an overall length of 1-3/8 inches. The headless design allows flush or recessed installation where a flange would interfere with the workpiece or fixture plate. The counterbored construction provides added flexibility for stacked or renewable bushing configurations. Machinists, toolmakers, and production fixture builders install this type of component when consistent drill guidance and hole location accuracy are required across repeated operations.

This bushing suits precision drilling and reaming operations in production and toolroom environments. It is sized to industry code P, with a letter drill designation of F and a decimal inside diameter of 0.2570 inches. The press fit installation method makes it appropriate for permanent fixture applications where the bushing is not intended to be field-replaced during a production run. Both light manufacturing and heavy industrial tooling setups use press fit headless bushings of this type in steel jig plates.

Key Features

• Press fit installation for permanent, secure seating in jig plates
• Headless design allows flush or below-surface mounting where flanges are not suitable
• Counterbored construction supports stacked bushing arrangements
• Steel construction for durability in high-cycle drilling and reaming applications
• Inside diameter tolerance of plus 0.0001 to plus 0.0005 inches for consistent tool guidance
• Conforms to industry bushing code P for standardized interchangeability

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard press fit headless drill bushing applications using industry code P bushings in steel jig and fixture plates.

Installation Notes

Press fit bushings are installed by qualified toolmakers or machinists using an arbor press or hydraulic press — never hammer directly onto the bushing body, as this can damage the bore or alter the fit. Ensure the receiving hole in the jig plate is machined to the correct press fit tolerance before installation. De-energize and lock out any associated equipment before servicing or replacing drill bushings in an active fixture. Consult applicable shop standards and fixture engineering documentation for correct press fit interference specifications.
