Hardened Undersized High-Speed M2 Tool Steel Rod Sets
- Hardness: Rockwell C60 (Very Hard)
- Yield Strength: Not Rated
Supplied in a metal index case with fold-out panels, these rods, also known as drill blanks, have an undersized diameter for machining your own jobbers'-length drill bits. They are hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.
