Measuring tool INSIZE 4801-15 radius gauge set 15.5–25 mm

INSIZE 4801-15 radius gauge set 15.5–25 mm is a precision instrument kit for verifying concave and convex radii within the 15.5 to 25 mm range. The set provides a series of accurately formed profiles that serve as a tactile and visual reference when checking curved surfaces, tool radii, dies and formed parts. Designed for workshop and inspection use, this radius gauge set supports metalworking, quality control and maintenance processes where consistent radius measurement is required.

Advantages

The radius gauge set offers a compact and durable solution for fast radius verification without the need for complex instruments. Each blade is formed to a specific radius to provide direct comparison against the inspected surface, reducing measurement uncertainty. The gauges are easy to handle and arrange, enabling efficient transition between different radii. The set’s dimensional range covers common mid-sized radii used in machining and forming operations.

Suitable for

• Checking concave and convex radii on machined parts
• Verifying tool and cutter radii
• Inspecting formed sheet metal and dies
• Quality control and incoming inspection
• Maintenance and on-machine checks

Key specifications

• Measuring range: 15.5–25 mm radius
• Set type: multiple profile blades covering the stated range
• Application: concave and convex radius comparison
• Material: hardened/form-stable gauge blades (manufacturing material provides stable reference profiles)
• Storage/organization: compact set for workshop use

How to use

Select the blade from the set that most closely matches the target radius, then place the profile against the part surface to check for full contact along the curve. For convex radii, apply the convex side of the gauge; for concave radii, use the matching concave profile. Observe any gaps or rocking to identify deviation from the nominal radius and move to adjacent blades if a finer match is required. Use in a clean environment and wipe surfaces before checking to avoid false readings due to debris or burrs.

Usage recommendations

Store the gauges in their case to protect profiles from damage and periodicy clean and inspect blades for wear. Use the set in combination with calipers or micrometers where dimensional traceability or numerical documentation is required.
