Provides a quick, efficient and inexpensive means to check steel hardness
Eliminates the need to bring the material to the hardness testing machine
Hardness testing files can reach into and test previously inaccessible areas.
The HARDNESS TESTING FILE SET comprises 6 colour coded files ranging from 40HRC to 65HRC in a protective plastic CASE.
The accompanying chart shows colour codes and file hardness.

To test material hardness start with the black handled file (65HRC) and run the file over the material.
If the file marks the material, the material is softer than the file. Repeat the procedure with the next , blue, file (60HRC) and continue the procedure until a file does not mark the material. The material hardness is then between the hardness of the two files that will and will not mark the material.
