About Tool Steel

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.

Oversized Multipurpose Air-Hardening A2 Tool Steel Rods and Discs

Yield Strength: 55,000 psi
Hardness: Rockwell B95 (Medium)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Rockwell C64

An oversized diameter allows for finishing to your exact requirements. 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. These rods and discs are decarb-free for a uniform surface that will consistently accept heat treating.

If you don't see the size you're looking for, please specify a length under additional rod lengths.

Hardened Tight-Tolerance Multipurpose Air-Hardening A2 Tool Steel Rods

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

Hardened for increased abrasion and impact resistance, these rods are precision ground with a tight diameter tolerance. Also known as drill rod, they're all set for turning applications in your lathe. 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.
