Fowler 52-760-000-0 Hardness Tester File Set - 40 to 65 HRC

The Fowler 52-760-000-0 Hardness Tester File Set provides an inexpensive and easy-to-use method for determining material hardness. By simply sliding the file across an object's surface, you can quickly identify hardness levels. This professional toolset features six color-coded files that cover a range from 40 to 65 HRC. To use, run the Black file (65 HRC) over your test material; if it marks the surface, the material is less than 65 HRC, and you can proceed to the Blue file (60 HRC) for more precise testing. This kit is designed for efficiency and includes a chart that shows the appropriate Vickers Hardness (HV) values. Everything is neatly organized in a portable, leather-like vinyl case with a Velcro-lined flap for secure storage.
