Starrett Individual Radius Gage - Millimeter, Steel

The Starrett Individual Radius Gage is a precision steel radius gauge (also called a radius gage or fillet gauge) for checking and measuring the radius of inside and outside corners, edges, and fillets. This metric version is graduated in millimeters. It suits machine shops, tool rooms, inspection departments, and fabrication work.

Key Features:

• Steel construction for durability and long-term wear resistance
• Millimeter sizing for metric part inspection
• Individual gage design so you can buy only the radius you need or replace a single worn gage
• Precisely ground radius profiles for accurate visual and tactile comparison against the part
• Made by Starrett, a trusted name in precision measuring tools

Use it to quickly check machined radii against print specifications, verify tooling, and support quality control. Hold the gage against the edge or corner and look for light gaps to see whether the radius matches. Wipe it clean and store it dry after use to keep it accurate.
