Frequently Asked Questions
Q: Can I use this tool to cut threads on hardened steel? A: No, the C-2 grade carbide is impact-resistant and optimized for cast iron and non-ferrous metals; it will wear rapidly if used on hard steels.
Q: Will a 12mm shank fit into a standard 1/2-inch tool post? A: Yes, 12mm is slightly smaller than 1/2 inch (12.7mm), allowing it to seat properly in holders with a 1/2-inch capacity.
