Specimen Marking Punches
Gauge point punches are used to punch mark a metallic specimen with a set gauge length before testing so that specimen elongation can be measured either during or after the test. Manual punches are available for a range of different gauge lengths.
Principle Of OperationManual gauge point punches require a strike with a hammer to punch mark the specimen. Standard punches consist of either a single set of punch points or a combination of two different sets of punch points. The punches are checked at the factory to provide punch marks at a predetermined, fixed gauge length. Special punches that provide multiple punch points spaced at fixed increments can also be purchased.
