Boneham P405JH Press Fit Headless Drill Bushing

Product Description

The BONEHAM P405JH is a press fit headless drill bushing used to guide drill bits and other cutting tools with precision during machining and fabrication operations. Manufactured from steel, this bushing features an inside diameter of 0.358 inches, a body outside diameter of 5/8 inches, and an overall bushing length of 5/16 inches. 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 tool travel. Machinists, toolmakers, and jig-and-fixture technicians install this type of bushing in drill jigs to maintain hole location accuracy across repeated operations.

The P405JH is intended for use in drill jig fixtures in both production and maintenance machining environments. It is pressed directly into a bored jig plate hole without the need for a liner bushing, making it appropriate for fixed-location, high-volume drilling applications where the bushing is not expected to be frequently replaced. The steel construction provides the hardness and wear resistance needed to withstand repeated tool contact in industrial shop settings.

Key Features

• Press fit installation — no liner bushing required
• Headless design sits flush with jig plate surface for unobstructed tool travel
• Steel construction for wear resistance and durability in production drilling
• Inside diameter tolerance of +0.0001 to +0.0005 inches for close tool guidance
• Bushing Industry Code P for straightforward cross-reference and replacement
• Non-renewable design optimized for fixed-location jig applications

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for press fit headless applications conforming to Bushing Industry Code P specifications.

Installation Notes

Press fit bushings are installed by toolmakers or machinist technicians using an arbor press to drive the bushing into a precision-bored hole in the jig plate. The receiving hole must be bored to the correct interference fit tolerance before installation. Never drive the bushing with a hammer directly against the bore face, as this can damage the inside diameter or distort the bushing. Ensure the jig plate and bushing are free of chips and burrs before pressing to seat.
