Grobet Inox Files are the hardest files in the world. Heat treated and hardened to Rockwell 72 to provide superior performance on hard-to-file surfaces. Their durability makes them resistant to clogging; a simple tap is enough to remove chips. They’re high performance files for use on platinum, stainless steel, hard plastics, and other hard-to-file materials. All file tangs are colored in yellow to distinguish them from your other files. Cut 00 is the coarsest, cut 6 is the finest. Made in Italy.
