Boneham P208FK Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P208FK is a press fit headless drill bushing manufactured from steel and designed to guide drill bits with precision in jig and fixture applications. With an inside diameter of 0.177 inches (wire gauge 16) and a body outside diameter of 5/16 inches, this bushing provides consistent bore alignment during repetitive drilling operations. The overall bushing length is 1/2 inches. The headless profile allows flush installation in close-clearance fixture plates. It is a non-renewable, fixed installation component intended for machining setups where permanent bushing placement is required. Machinists and tool-and-die technicians install this type of bushing using a press.

This bushing is suited for use in drill jigs, fixture plates, and production tooling where accurate hole location and drill guidance are critical. The press fit installation method secures the bushing firmly in the fixture body without requiring a retaining ring or locking mechanism, making it appropriate for high-volume drilling operations in both job shop and manufacturing environments. The steel construction supports standard twist drill and step drill applications across a wide range of workpiece materials.

Key Features

• Press fit installation method provides a secure, permanent fixture without additional hardware
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches ensures accurate drill guidance
• Steel construction offers durability for repeated drilling cycles
• Non-renewable design for permanent fixture applications
• Bushing Industry Code: P for straightforward catalog cross-reference

Compatibility

Designed as an OEM-style replacement or new-installation component for standard drill jigs and fixture tooling requiring a press fit headless bushing with a P industry code designation.

Installation Notes

Installation is performed by pressing the bushing into a pre-machined hole in the fixture plate using an arbor press or hydraulic press — never drive with a hammer directly on the bushing face. Ensure the receiving bore is clean, free of burrs, and machined to the correct press fit tolerance before installation. Once pressed in, the bushing is not intended to be removed and reused. Always verify bushing inside diameter alignment with the intended drill size before committing to final fixture assembly.
