Diamond hardness tester indenter: Diamond indenters are suitable for various instruments such as Rockwell hardness tester, Vickers hardness tester, Knoop hardness tester, etc.

It is a process of grinding a high-quality natural diamond of a specified weight into a standard geometric shape with certain technical requirements, using a conical indenter (cone angle of 120 degrees) and a regular quadrangular pyramid indenter (with three types of relative angular angles: 130 degrees, 136 degrees, 172 degrees, and 30 minutes).
