PORTABLE HARDNESS TESTERS

PORTABLE HARDNESS TESTING FILE SET

PART  NO: 6499-HTF6

The set contains 6 colour coded files ranging from HRC40-HRC 65 in a protective plastic case.

This set  provides a quick inexpensive means to check steel hardness

The files allow easy testing of difficult to reach areas, eliminating  the need to bring the material to the hardness testing machine.

Testing is easy.  Start with the black handled (hardest) HRC65,  file 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 HRC60 and repeat the procedure until the 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.
