A Radius Gauge sometimes called a Fillet Gauge is a tool used for measuring the radius of an object. The hand-held tools are made up of thin metal, (usually stainless steel) precision blades or leaves with rounded curves. The thin blades are screwed together and held together by a lock screw. RS offer a range of high-quality precision gauges from leading brands including Kleffmann & Weese and of course our own trusted RS PRO brand.
The gauges are available in metric or imperial types and have the capability to check convex and concave profiles. A convex radius curve outwards and a concave radius curves inward.
Radius gauges are used in many industrial and commercial pattern-making, precision machining and part inspection and measuring applications.
