Starrett 55811 Radius Gage 10mm Stainless Steel

Product Description

The STARRETT 55811 is a radius gage leaf designed to measure both convex and concave radii up to 10mm. Machined from stainless steel with a satin chrome finish, the leaf delivers consistent dimensional readings in shop and field conditions. The satin chrome surface reduces glare under work lighting, making it easier to read the fit between the gage and workpiece. This type of gage is standard equipment for machinists, tool-and-die workers, fabricators, and quality-control technicians who need to verify radii on turned, milled, or stamped components.

This gage leaf is suited for use in machine shops, fabrication facilities, and quality inspection settings where radius verification is part of the workflow. The convex-and-concave configuration on a single leaf allows the technician to check both inside and outside radii without switching tools. It is appropriate for use on metal, plastic, and other rigid materials where a 10mm radius specification must be confirmed.

Key Features

• Measures both convex and concave radii on a single leaf
• Maximum radius capacity: 10mm
• Stainless steel construction for corrosion resistance and long service life
• Satin chrome finish reduces glare during inspection
• Compact leaf form factor fits easily into a toolbox or inspection kit

Compatibility

Designed as an OEM-style radius gage leaf suitable for general-purpose radius inspection on rigid materials in machining and fabrication environments.

Installation Notes

No installation is required for this hand-tool gage leaf. To use, hold the appropriate radius profile firmly against the workpiece surface and check for light gaps to confirm fit. Keep the leaf clean and dry to prevent corrosion and maintain measurement accuracy. Store in a protective case or pouch away from abrasive materials that could damage the gage profile.
