Starrett 279 radius gage set with 20 precision-ground leaves covering .020 to .400 inches. Each leaf measures fillet and radius profiles accurately. The set is organized in a holder for convenient selection and storage.

Fillet or Radius Gage is an external and internal radius on each leaf permits both concave and convex surfaces to be measured. The leaves are specially shaped for use in any position at any angle to measure fillets and radii in corners or against shoulders.

Features

• Provides twenty leaves with radii from 0.020 to 0.400 in inclusive
• Includes nine leaves have concave and convex radii from 0.02 to 0.1 in inclusive by 0.01 in
• Includes four leaves with concave and convex radii from 0.125 to 0.2 in inclusive by 0.025 in
• One leaf with concave and convex radii of 0.25 in from 0.3 to 0.4 inclusive by 0.05 in and three leaves with convex radii from 0.3 to 0.4 by 0.05 in
• Includes three leaves with concave radii only
• Leaves are specially shaped for use in any position at any angle to measure fillets and radii in corners or against shoulders
• Each leaf is stamped with the radius size and has an eccentric mounting for clearance between the leaf and the case when the gage is opened
• Inch system of measurement
