Boneham P4022IU Press Fit Headless Drill Bushing

Product Description

The BONEHAM P4022IU is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. With an inside diameter of 21/64 inches, a body outside diameter of 5/8 inches, and an overall length of 1-3/8 inches, this bushing provides accurate, repeatable hole location in production drilling operations. Manufactured from steel, it is pressed directly into a drill jig plate without a locking head, making it well suited for permanent or dedicated fixture installations. Machinists, tool and die makers, and production shop personnel are the primary installers of this component.

The P4022IU is used in metal fabrication, machining, and tooling environments where consistent hole placement across multiple workpieces is required. It is appropriate for both light and medium-duty drilling jigs in industrial and manufacturing settings. The headless design keeps the bushing flush or recessed within the jig body, which is preferred when head clearance is limited or when a clean jig surface is required. This bushing is a non-renewable type, intended for fixed installation rather than field replacement under production conditions.

Key Features

• Press fit installation method for secure, permanent seating in drill jig plates
• Headless design provides a flush or recessed profile in the jig body
• Inside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures precise drill guidance
• Steel construction for durability in production drilling applications
• Non-renewable bushing rated for fixed, dedicated fixture use
• Bushing industry code P for standardized interchangeability reference

Compatibility

Designed as an OEM-style press fit headless drill bushing for use in standard drill jig plates and machining fixtures requiring a 5/8 inches outside diameter bore.

Installation Notes

Installation is typically performed by a machinist or toolmaker using an arbor press to drive the bushing into a precision-bored hole in the jig plate. The receiving bore in the jig should be machined to the appropriate press fit tolerance before installation to avoid damage to the bushing or plate. Once pressed in, the bushing is not intended for removal or reuse. Always verify the bore diameter and bushing dimensions before pressing to ensure proper fit and alignment.
