Hardened Undersized High-Speed M2 Tool Steel Rods

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.

Tight-Tolerance Multipurpose Air-Hardening A2 Tool Steel Rods

Precision ground and held to a strict straightness tolerance, these rods are ready for turning in your lathe. They’re also known as drill rod. A2 tool steel is more wear resistant than O1 and it keeps a sharper cutting edge. This air-hardening material is widely used for punches, broaches, and dies.
