Gimex MWKc/A3 Arc Gauge 15.5–25 mm Radius Gauge (model 318.007)

The Gimex MWKc/A3 Arc Gauge (model 318.007) is a compact radius measuring template designed for accurately checking and marking convex and concave arcs with a scale range of 15.5–25 mm. Made for workshop, fabrication and repair environments, this gauge helps inspect curved workpieces, verify radial dimensions and assist in layout and quality control where repeatable radius measurement is required.

Advantages

The arc gauge provides a simple, durable and precise method to measure small radii without complex setup. Its compact form factor allows easy handling and placement on a variety of curved surfaces. The clear scale range of 15.5–25 mm covers common small-radius applications, enabling quick comparison and marking directly on the workpiece. The tool is suitable for frequent use in production and repair settings where repeatability and straightforward verification are important.

Suitable for

• Inspection and verification of curved profiles and fillets in metalworking and fabrication
• Layout and marking of radii on sheet metal, tubing and molded parts
• Repair work where matching or checking existing radii is required
• Quality control checks during small-batch production and finishing

Key specifications

• Radius measurement range: 15.5–25 mm
• Function: template for checking and marking convex and concave arcs
• Application area: workshop, fabrication, repair and quality control
• Form factor: compact, hand-held gauge suitable for direct placement on workpieces

How to use

Select the portion of the gauge that corresponds to the required radius within the 15.5–25 mm range and place it against the curved surface to be checked or marked. Ensure the gauge sits flush along the arc to confirm a match or identify deviation. For marking, align the gauge at the intended position and scribe along the template edge. Use light, controlled pressure to avoid damaging delicate surfaces and repeat checks at multiple points along the curve to verify consistency.

Usage recommendations

Keep the gauge clean and free of burrs or debris to maintain measurement accuracy. Store it in a dry place to prevent corrosion and avoid bending or dropping the template to preserve its shape. When working on finished surfaces, protect the part and the gauge contact edge with a thin protective layer or use fine scribing to prevent surface damage.
