Convex Concave Radius Gauge Silver Tone R15-25mm Measure Tool by Uxcell

Crafted from robust carbon steel, this tool boasts a chrome-plated surface for rust resistance, high hardness, and excellent wear resistance. Its non-deformable design features a user-friendly notched shell and a 360-degree locking screw for easy folding and release. Ideal for measuring items with rounded corners, one side measures convex surfaces while the other measures concave surface radii. Laser-engraved scales ensure clear readability, even after prolonged use. Primarily used for arc surface radius measurement, such as shaft processing surfaces, steel pipes, and ceramic pipe inspections. To maintain tool longevity, avoid stacking with other metal tools and clean with a soft cloth post-use.
