Starrett Radius Gage Concave Convex Measurement Tool

The Starrett radius gage is a precision radius gauge for checking concave (inside) and convex (outside) radii on machined parts, fillets, corners and edges. Each leaf in the set is marked with its radius, so you can quickly compare a part's profile against a known reference. Machinists, toolmakers, inspectors and fabricators use this type of gage, also called a radius template or fillet gauge, for fast go/no-go visual checks.

Key Features:

• Measures both concave and convex radii with a single tool
• Leaves are clearly marked with their radius values for easy identification
• Precision-made by Starrett, a long-established American maker of measuring and precision tools
• Durable construction suited to shop and inspection-room use
• Compact, portable design for use at the machine, bench or inspection station

Hold the correct leaf against the edge or fillet and check the fit against a light source. Any gap shows that the radius is off. Starrett's reputation for accuracy and build quality makes this line a dependable choice for quality control, machining, tool and die work, and general metalworking.
