Boneham P405IR Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P405IR is a press fit headless drill bushing used to guide drill bits and other cutting tools with precision in jig and fixture applications. It carries a P-series industry code and features a 0.323 inch inside diameter, a 5/8 inch outside diameter, and an overall bushing length of 5/16 inches. Machined from steel, this headless style bushing seats flush into a drill jig plate without a flange, making it suited for applications where a low-profile installation is required. It is a permanent, non-renewable bushing installed by press fit into a prepared bore. Machinists, toolmakers, and fixture builders are the primary installers.

This bushing is used in metalworking and machining environments where repeatable hole location accuracy is critical. It fits into drill jig plates, fixture blocks, and tooling bodies that require a steel guide bushing with tight inside diameter tolerances. The inside diameter tolerance is held to a range of plus 0.0001 to plus 0.0005 inches, making it suitable for precision drilling, reaming, and light boring operations. It is appropriate for production and job-shop environments using standard P-series jig bushing tooling layouts.

Key Features

• Press fit installation for permanent, interference-fit seating in jig plates
• Headless design provides flush, low-profile mounting with no flange
• P-series bushing industry code for standardized tooling compatibility
• Inside diameter tolerance of plus 0.0001 to plus 0.0005 inches for precision guidance
• Steel construction for durability in repeated drilling cycles
• Non-renewable design — intended as a fixed, single-installation bushing

Compatibility

Designed as an OEM-style replacement or direct-fit addition for P-series press fit headless drill jig bushing applications in standard drill fixture tooling systems.

Installation Notes

Installation is performed by pressing the bushing into a precision-bored receiver hole in the jig plate using an arbor press or hydraulic press — never drive with a hammer directly on the bushing bore. The receiver bore must be machined to the appropriate interference fit for a press fit bushing before installation. Once seated, this bushing is not intended to be removed and reused. Follow applicable shop safety and tooling standards when preparing fixture bores and pressing components.
