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.
