Tight-Tolerance Air-Hardening A2 Tool Steel Bars
 |
These bars, also known as flat stock, are precision ground to a tight thickness tolerance. 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.

Air-Hardening A2 Tool Steel Bars
|
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. The thickness, length, and width are oversized for finishing to your exact requirements. These bars are also known as flat stock.
If you don't see the size you're looking for, check out our Made-to-Order A2 Tool Steel Bars.
Precision Ground—Precision-ground bars have less stock to remove on the top, bottom, and sides for achieving a finished piece faster.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Tight-Tolerance Air-Hardening A2 Tool Steel Rods
 |
Precision ground and held to a strict straightness tolerance, these rods are ready for turning in your lathe. Also known as drill rod, this A2 tool steel is more wear resistant than O1 and keeps a sharper cutting edge. It’s air-hardening, so it doesn’t require baths or quenching after heat treatment. This tool steel is often used for punches, blades, and hammers.

Air-Hardening A2 Tool Steel Rods
Made of A2 steel, they are more wear resistant than O1 rods and discs. They also keep a sharper cutting edge. When heat treated for added wear resistance, they don’t require baths or quenching and can be air-hardened. A2 tool steel is widely used for punches, blades, and hammers. These rods and discs are decarb-free, which means any surface flaws created during the manufacturing process have been removed. This makes them more machinable and leads to better results from heat treating or finishing. With an oversized diameter, these rods and discs let you finish to your exact requirements.

Tight-Tolerance Air-Hardening A2 Tool Steel Sheets
 |
These sheets, also known as flat stock, are precision ground to a tight thickness tolerance. 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.

Made-to-Order A2 Tool Steel Rods
 |
When an off-the-shelf size won't do, we'll get you the exact dimensions you need.
Made of A2 steel, they are more wear resistant than O1 rods and discs. They also keep a sharper cutting edge. When heat treated for added wear resistance, they don’t require baths or quenching and can be air-hardened. A2 tool steel is widely used for punches, blades, and hammers. These rods are decarb-free, which means any surface flaws created during the manufacturing process have been removed. This makes them more machinable and leads to better results from heat treating or finishing. With an oversized diameter, these rods and discs let you finish to your exact requirements.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Hardened Tight-Tolerance Air-Hardening A2 Tool Steel Rods
|
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.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
