SPI 98-724-Rockwell Hardness Testing File: Light Green Handle, 50 RC
Specially-shaped file has a nonslip-grip, color-coded handle with the Rockwell value printed for easy identification
A curved file tip can reach into internal slots, grooves, and bores that cannot otherwise be tested with conventional types of fixed or portable hardness testers
Convenient and portable, the hardness testing file can be taken to out-of-factory sites to test for hardness on large structures or segments of machinery
