Mitutoyo 186-901 Radius Gauge Set, Range 1/64″-1/2″

The Mitutoyo Radius Gauges are recommended for checking or laying out concave or convex radii. An individual gauge for each dimension makes it possible to verify radius or fillet dimensions easier, faster, and more accurately in machining, layout, inspection, and pattern-making work. The measuring surfaces are precisely finished with smooth, accurate edges.
