Boneham CB00001281 Press Fit Headless Drill Bushing

Product Description

The BONEHAM CB00001281 is a press fit headless drill bushing manufactured from steel, designed to guide drill bits and other cutting tools with precision in jig and fixture applications. Classified as a P-type bushing, it features an inside diameter of 0.1285 inches (Wire Size 30) with a tight tolerance of +0.0001 to +0.0004 inches, an outside diameter of 5/16 inches, and an overall length of 1 inch. 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. Installation is permanent - the bushing is pressed directly into a prepared hole and is not renewable.

This bushing is used in precision machining, toolmaking, and fabrication environments where repeatable hole location is required across multiple workpieces. P-type press fit headless bushings are a standard component in drill jigs across metalworking and general manufacturing. They are typically installed in hardened jig plates or fixture bodies where the bushing must remain fixed during high-volume drilling operations. Machinists, toolmakers, and fixture builders will encounter this bushing in production and prototype setups alike.

Key Features

• P-type press fit design for permanent, fixed installation in jig plates
• Inside diameter of 0.1285 inches (Wire Size 30) with +0.0001 to +0.0004 inch tolerance for precise tool guidance
• Outside diameter of 5/16 inches, overall length of 1 inch
• Headless body sits flush with the jig plate surface, eliminating head interference
• Steel construction provides durability under repeated drilling cycles
• Non-renewable - intended for permanent press fit installation

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard P-type press fit headless drill bushing applications in machining jigs and fixtures.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing flush into a prepared, reamed hole in the jig plate. The mating hole in the fixture should be machined to the appropriate interference fit tolerance before pressing. Do not drive the bushing in with a hammer, as uneven force can distort the bore. Once pressed in, this bushing is not designed to be removed and replaced.
