Radius Gauge Set 5.5-13mm Keyring

This precision radius gauge set is designed for engineers and machinists who need quick and accurate radius checks. It includes 16 metric blades covering 5.5mm to 13mm in 0.5mm increments, suitable for both internal (concave) and external (convex) radii.

Made from durable stainless steel, each blade is clearly marked for easy identification and long-lasting performance in workshop environments. The blades are neatly mounted on a compact ring, making it convenient to carry, store, and use on-site or at the bench.

Ideal for checking fillets, tool sharpening, re-machining, and general inspection work.
