Starrett Reading Fillet or Radius Gage - Versatile Concave & Convex Measurements - 0.020-inch to 0.400-inch Range, 20 Leaves - 279

The Starrett 279 Inch Reading Fillet or Radius Gauge has 20 leaves to measure 0.02" to 0.40" concave or convex radii in woodworking, metalworking, machining, layout, and pattern-making applications. The 20 shaped leaves measure at any angle and are stamped with the radius size for accurate sizing. It measures concave or convex radii from 0.02" to 0.40", inclusive, in varied increments. It has an eccentric mounting that provides clearance between the leaf and the case when the gauge is open.Nine leaves measure concave and convex radii from 0.020" to 0.10" inclusive by 0.010". Four leaves measure concave and convex radii from 0.125" to 0.20" inclusive by 0.025". One leaf measures concave and convex radii of 0.250". Three leaves measure concave radii only from 0.3" to 0.4" inclusive by .050" and three leaves measure convex radii only from .300 to .400 by .050"The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company, founded in 1880, is headquartered in Athol, MA.

• Precise Measurement Capability - Measures both concave and convex surfaces with radii from 0.020-inch to 0.400-inch, ensuring accuracy for a wide range of applications.
• Versatile and Easy to Use - Specially shaped leaves allow for use at any angle, making it easy to measure fillets and radii in corners or against shoulders.
• Comprehensive Range - Includes 20 leaves with detailed increments for precise measurements: nine leaves from 0.020-inch to 0.10-inch, four from 0.125-inch to 0.20-inch, and others up to 0.400-inch.
• Durable and Reliable - Each leaf is stamped with the radius size and eccentrically mounted, providing long-lasting durability and easy identification during use.
