Boneham P206FX Press Fit Headless Drill Bushing

Product Description

The BONEHAM P206FX is a press fit headless drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Manufactured from steel with a hardness of 60 to 65 HRC, this bushing resists wear under repeated tooling cycles. It features a 0.1935 inch inside diameter (equivalent to a No. 10 wire gauge drill), a 5/16 inch body outside diameter, and a 3/8 inch overall length. The inside diameter tolerance is held to +0.0001 to +0.0004 inches, ensuring consistent tool alignment across production runs. Machinists, tool and die makers, and fixture builders install this type of bushing into jig plates and drill fixtures.

This bushing is suited for jig and fixture applications in production machining environments, both light and heavy manufacturing. The headless design allows it to sit flush within the jig body, making it appropriate for close-tolerance layouts where a flanged head would interfere with workpiece contact or adjacent bushings. Industry code P identifies it as a standard headless press fit type per ANSI specifications, allowing straightforward cross-referencing on fixture drawings and procurement documents.

Key Features

• Press fit installation method — no set screw or retaining ring required
• Headless design seats flush in jig plate for unobstructed workpiece contact
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• ANSI-compliant bushing industry code P for standard fixture drawing callouts
• Non-renewable design — intended as a permanent press fit installation

Compatibility

Designed as an ANSI-standard press fit headless drill bushing suitable for use in jig plates and drill fixtures requiring a 5/16 inch body outside diameter and 0.1935 inch inside diameter tool guidance bore.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or hydraulic press. The receiving hole in the jig plate must be finish-bored or reamed to the correct interference fit tolerance before pressing the bushing in place. Power down all associated machine tooling before handling jig components. Do not drive the bushing with impact tools, as this may damage the bore geometry or crack the jig plate.
