Boneham P4016KE Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P4016KE is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured from steel, this bushing features a 0.404 inch inside diameter, a 5/8 inch body outside diameter, and a 1 inch overall length. The inside diameter tolerance of +0.0001 to +0.0005 inches ensures accurate, repeatable tool guidance across production runs. The headless design sits flush with the jig plate surface, making it well suited for applications where a protruding head would interfere with workpiece clearance or tooling access. Installation is permanent — this bushing is not renewable once pressed in place.

This bushing is intended for use in drill jigs and machining fixtures in manufacturing, toolroom, and production environments. Industry code P identifies the bushing type within the standard drill bushing classification system. It is installed by toolmakers, machinists, and fixture builders wherever precise hole location and consistent tool guidance are required. The 1 inch overall length provides adequate bearing surface for common drill and reamer diameters in the 0.404 inch range.

Key Features

• Press fit installation method — no locking collar or fastener required
• Headless design for flush, low-profile seating in jig plates
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Steel construction for durability in production drilling applications
• Non-renewable fixed bushing — intended as a permanent fixture component
• Industry code P classification for standard bushing identification

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing for use in standard drill jigs and machining fixtures requiring a 0.404 inch inside diameter and 5/8 inch outside diameter bushing per industry code P.

Installation Notes

Installation is performed by a machinist or toolmaker using an arbor press or hydraulic press to seat the bushing flush and square in the jig plate bore. The receiving bore in the fixture plate must be machined to the correct interference fit tolerance before installation. Once pressed in, the bushing is permanent and cannot be removed without damaging the plate or bushing. Follow standard toolroom fixture-building practices and verify bore alignment before pressing.
