Radius Gauge B This radius gauge has an internal and external radius on each leaf. This means each leaf can measure a concave and convex surface. This type of gauge is used by toolmakers and inspectors to measure the edges and corners of work pieces, usually made from metal.
Radius gauge 25mm increments Both ends of the gauge support leaves containing both concave and convex measuring capabilities.
Leaves suitable for checking a concave or convex radius As each leaf has a separate measurement, this means a wider range can be covered compared to the other radius gauge set with single function blades at either end of the tool.
Outside and inside radius on one blade Each leaf is stamped with a size which refers to both the internal and external radius in imperial or metric.
Using the inside of a leaf to measure a convex radius A multi-function radius gauge blade can be used to check a convex radius. To do this, use the internal side of the gauge.
Use the external side of the leaf to measure a concave radius A multi-function radius gauge blade can be used to measure a concave radius. This may also be referred to as a fillet or a shoulder. To do this use the external side of the tool.

What are the advantages?

Radius gauge B advantages The advantage is that it is suitable for checking edges and corners of work pieces in any position, including in corners known as ‘shoulders’ (bends created for added structural strength).

What are the disadvantages?

Radius gauge B disadvantages The disadvantage is that locating the correct part of the double sided blade to use for each application may not be as simple as having a blade with a single designated function.
