About Tool Steel

Yield Strength: Not Rated
Hardness: Rockwell C60 (Very Hard)

These rods, also known as drill blanks, have an undersized diameter for machining your own jobbers'-length drill bits. They're 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.

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.
