The VALUE COLLECTION 615-4809 is a chrome-coated steel radius gage used to measure and verify concave or convex radius profiles during fabrication, machining, and inspection work. At 9/64 inch radius, this gage serves as a go/no-go reference for checking fillets, chamfers, and rounded edges on machined components. The chrome coating provides corrosion resistance and surface durability. Weighing just 0.003 pounds, it is a lightweight, single-piece inspection tool suited for shop floor or bench use.
This radius gage is used in metal fabrication shops, machine shops, and maintenance environments where consistent radius verification is required. It is appropriate for inspecting tooling, castings, stampings, and machined parts. Machinists, tool and die makers, and quality control technicians typically use radius gages as part of dimensional verification workflows.
Designed as a standard 9/64 inch radius gage suitable for general-purpose dimensional inspection of machined, cast, or stamped components requiring radius profile verification.
Radius gages are inspection tools and require no installation. Clean the gage and the workpiece surface before use to ensure accurate contact and reading. Store the gage in a protected case or pouch to prevent edge damage and maintain measurement accuracy. Handle with care to avoid dropping, which can deform the profile edge and compromise gage accuracy.
