The optional West Cerchar specialty indenters are a set of additional tools for use with the West Cerchar Abrasivity Index Tester. The set includes one hundred (100) sharp steel indenters, also referred to as stylus pins.

Each indenter features a tip with a conical angle of 90°. These indenters are vital components of the tester, playing a key role in performing the abrasivity test. They are used to scratch the rock sample, and the degree of wear on the indenter’s tip after the test provides an indication of the sample’s abrasivity.

Having additional indenters at hand can be beneficial for a variety of reasons. For instance, in situations where testing needs to be conducted rapidly or in high volumes, having spare indenters can reduce downtime associated with stylus sharpening. Moreover, in cases where an indenter gets excessively worn or damaged, a replacement can be readily available. Hence, while these specialty indenters are optional, they can significantly enhance the efficiency and convenience of the abrasivity testing process.
