Hardness Tester File SET

Description

The TTC Hardness File Set provides an easy-to-use method for ascertaining material hardness, which can be determined by sliding the files across the surface of the material you are testing. The set includes six color coded files, which indicate hardness ranging from 40 to 65 HRC. As illustrated in the video, simply run the file across the surface of the object, starting with the hardest (65 HRC) file. If the file marks the surface, the material is less than 65 HRC. You would then proceed to the next hardest file (60 HRC) and repeat the process as needed until the hardness file is unable to mark the surface of he object you are testing. The approximate hardness of the material will be between the file that marks the surface and the most recent file to slide over the material without leaving a mark.
