401108 Radius Measuring Gauge Variation
Radius gauges require a bright light behind the object to be measured. The gauge is placed against the edge to be checked and any light leakage between the Plates and edge indicates a mismatch that requires correction.
Metric set, very usefull gauge for Tool & Die makers, machinists, screw machine operators, patternmakers, layout men and other mechanics to lay out and check the radii of tools, dies, patterns etc
All gauges have locking device
Specialy shaped so the can measure fillets and radii in corners or against shoulders
Each leaf is marked
