Mitutoyo 186-902 Radius Gauge Set, 0.5 to 13mm
Available
A radius gauge checks the radius of an inside or outside corner. Each Mitutoyo Series 186 leaf has a concave (inside) and a convex (outside) radius of the same size, and the size is stamped on the leaf. You match a leaf to the corner and read the radius off it. Toolrooms, machinists, inspectors and pattern makers use them to check fillets and rounded edges.
There are five metric sets. The 186-110 covers 0.4 to 6mm, the 186-105 covers 1 to 7mm, the 186-106 covers 7.5 to 15mm and the 186-107 covers 15.5 to 25mm. The 186-902 is a 26-leaf set that runs from 0.5 to 13mm in 0.5mm steps. Choose by the radius sizes you check most. Each gauge has a locking clamp and five measuring locations.
