Answer:

Two types of indenters are used: a 1/16” diameter steel ball (used for surface hardnesses of brasses, aluminum sheet, etc.) and the N-Brale penetrator. This Brale penetrator is like the one used in the standard Rockwell hardness tests except the spherical end is shaped to higher tolerances.
