These unique instruments are the most economical way of grading and checking various metals in equivalent Rockwell C range of 20HRC to 67HRC and Rockwell B range from 40HRB to 100 HRB.

The chassis is made from aerospace aluminum, which houses a high precision displacement gauge. The shank at the top is used to hold the instrument in a mill, drill press, or lathe chuck. The lower end contains the indenter and mainspring.

The impression made The impression made by the indenter in the metal being tested is very small and is equivalent to a superficial examination in size. The travel of the indenter, caused by the resistance of the metal sample surface, results in the dial readout in equivalent Rockwell B Scale. Minimum sample thickness is 0.025" for most materials. If the indenter does not make a dimple on the opposite side, the material is thick enough for accurate testing.


The instruments come complete with two test blocks (high and low ranges), conversion chart, and carrying case.
