Boneham CB00001203 Headless Drill Bushing 0.213 Id

Product Description

The BONEHAM CB00001203 is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. Classified under Industry Code P, this bushing features an inside diameter of 0.213 inches with a close tolerance of +0.0001 to +0.0004 inches, ensuring accurate hole location and repeatable results. The body outside diameter measures 0.5 inches and the overall length is 1 inch. Constructed from steel, this bushing provides the hardness and wear resistance required for production drilling operations. Machinists, toolmakers, and fixture builders are the primary installers of this component.

This bushing is suited for use in drill jigs and machining fixtures in industrial, manufacturing, and fabrication environments. The headless design allows the bushing to sit flush within a jig plate without a protruding flange, making it appropriate for applications where clearance above the plate is limited or where a smooth top surface is required. It is pressed directly into a reamed hole in the jig body and is not designed for removal and replacement in service — it is a fixed, permanent installation.

Key Features

• Industry Code P classification for standardized press fit headless drill bushing sizing
• Inside diameter of 0.213 inches (wire gauge size 3) with tight tolerance of +0.0001 to +0.0004 inches
• Body outside diameter of 0.5 inches and overall length of 1 inch for adequate drill guidance depth
• Steel construction for hardness and wear resistance in production drilling applications
• Headless design for flush installation in jig plates with restricted overhead clearance
• Non-renewable fixed installation — press fit into reamed fixture hole for permanent use

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and machining fixtures requiring a press fit headless bushing with a 0.213 inch inside diameter and 0.5 inch outside diameter per Industry Code P standards.

Installation Notes

Installation is performed by toolmakers or machinist professionals using a drill press or arbor press to drive the bushing into a precision-reamed hole sized to the bushing outside diameter tolerance. The receiving hole in the jig plate must be reamed to the correct interference fit dimension before pressing the bushing in place. Do not hammer directly on the bushing bore — use a flat press tool or driver that contacts the outer face only. Once pressed in, this bushing is not designed for field removal or reuse.
