The Mitutoyo Radius Gauge Set (Model 186-105) is a precision tool designed to quickly verify radii on parts, edges, and contoured features. This 17-pair leaf set covers a practical range from 1.0 mm to 7.0 mm, with 0.25 mm steps from 1.0 to 3.0 mm and 0.5 mm steps from 3.5 to 7.0 mm. Each gauge is stamped with its exact radius size for fast reading, and the set includes both concave and convex leaves to measure internal and external radii with a single, compact tool.

  • Broad, precise radius range: covers 1.0–3.0 mm in 0.25 mm steps and 3.5–7.0 mm in 0.5 mm steps, with all sizes clearly stamped on the leaves for quick identification.
  • Concave and convex leaves in one set: enables internal and external radius checks without changing tools, streamlining your workflow.
  • Locking clamp for secure, repeatable measurements: locks the gauge in place during inspection, reducing drift and ensuring consistent readings over multiple checks.

This radius gauge set helps you verify fillets and round features faster, improving measurement reliability and reducing rework in machining, fabrication, inspection, and maintenance tasks. The combination of clearly stamped sizes, dual-radius profiles, and a locking clamp supports accurate, repeatable results across a wide range of applications—so you can trust your measurements and keep projects moving smoothly.

Buying experience
Phone requests are handled quickly and without any fuss. The website is easy to use and straightforward to order from. It’s especially helpful that it shows real‑time availability, so we don’t need to call to confirm whether parts will arrive.
