Mitutoyo 186-903 Radius Gage Set 1/64-17/64 Inch 17 Leaves Concave/Convex

The Mitutoyo 186-903 is a precision radius gage set designed for accurate measurement of concave and convex radii in machining, inspection, layout, and pattern-making applications. This 17-leaf set covers radius dimensions from 1/64 inch to 17/64 inch in increments of 1/64 inch, providing comprehensive coverage for common small radius measurements.

Key Features:

• 17 individual leaves ranging from 1/64 inch to 17/64 inch by 64ths
• Each leaf measures both concave and convex radii for versatile inspection capabilities
• Precisely finished measuring surfaces with smooth, accurate edges for reliable measurements
• Individual gages for each dimension enable faster, easier, and more accurate radius and fillet verification
• Compact set design allows quick selection of the correct gage size

This radius gage set is an essential tool for machinists, inspectors, and toolmakers who need to verify radius dimensions on machined parts, fillets, and rounded edges. The individual leaf design eliminates the need for interpolation between sizes and ensures precise go/no-go checking of critical radius specifications.
