Boneham CB00001211 Headless Drill Bushing 0.204 Id Steel

Product Description

The BONEHAM CB00001211 is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Carrying industry code P, this bushing features an inside diameter of 0.204 inches with a tight tolerance of +0.0001 to +0.0004 inches, ensuring accurate tool guidance and repeatable hole location. The outside diameter measures 13/32 inches and the overall length is 1 inch. Constructed from steel, it delivers the hardness and wear resistance required for production drilling operations. Machinists, toolmakers, and fixture builders install this type of bushing as a permanent component in drill jigs.

This bushing is suited for use in drill jig fixtures in light manufacturing, toolroom, and production machining environments. The headless press fit design makes it appropriate for installations where the bushing must sit flush with or below the jig plate surface, eliminating interference with drill guides or chip clearance. It is sized for a number 6 wire gauge drill or equivalent 0.204-inch tooling. No renewable liner is used, making this a fixed, non-removable installation intended for high-volume or permanent setups.

Key Features

• Industry code P headless press fit configuration for flush or sub-flush jig plate installation
• Inside diameter of 0.204 inches with tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Outside diameter of 13/32 inches for standard jig bore fitment
• Overall length of 1 inch provides full tool support through moderate plate thicknesses
• Steel construction offers hardness and wear resistance for production drilling cycles
• Non-renewable, fixed installation — no liner required

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing for use in standard drill jig fixtures requiring a P-series bushing with 0.204-inch inside diameter and 13/32-inch outside diameter.

Installation Notes

Press fit bushings are installed by toolmakers or machinist tradespeople using an arbor press or hydraulic press — never driven with a hammer, as this can damage the bushing bore or distort the jig plate. The receiving bore in the jig plate must be machined to the appropriate interference fit tolerance for the 13/32-inch outside diameter before installation. Once pressed in, this bushing is not designed for removal or replacement. Always verify bore alignment and cleanliness before pressing.
