Drill Rod Tool Steels 03720117 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03720117 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, die makers, and fabricators who require a dimensionally consistent, machinable steel blank ready for heat treatment. This bar measures 0.75 inches thick, 2.5 inches wide, and 36 inches long, with a shipping weight of 19.74 pounds. A2 tool steel is an air-hardening, cold-work grade known for its good dimensional stability during hardening and strong wear resistance after heat treatment, making it a standard choice for dies, punches, gauges, and cutting tools in production and toolroom environments.

This flat stock is suited for fabrication of cold-work tooling components in job shops, tool-and-die operations, and maintenance departments. The 36-inch length provides enough stock for multiple tooling blanks from a single piece. The material arrives in the annealed condition, ready for machining before hardening. It is appropriate for applications where moderate toughness and good wear life are required, such as forming dies, blanking punches, shear blades, and gauging fixtures.

Key Features

• AISI A2 air-hardening cold-work tool steel for stable, distortion-controlled heat treatment
• Thickness tolerance of +0.010 to 0.015 inches for consistent stock removal planning
• Width tolerance of +0.010 to 0.015 inches
• Length tolerance of +0.250 to 0.500 inches
• Square tolerance of +/- 0.003 inches for reliable setup and fixturing
• Supplied in annealed condition, machinable before hardening

Compatibility

Designed as a standard A2 tool steel flat stock blank suitable for cold-work tooling applications requiring air-hardening material per AISI A2 specification.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with cold-work tool steel procedures. Follow established shop practices for annealed tool steel machining, and consult the material specification for recommended hardening and tempering cycles before applying heat treatment. Always allow stock for finish grinding after hardening to achieve final dimensional tolerances. Use appropriate personal protective equipment when cutting or grinding tool steel.
