Drill Rod Tool Steels 03718392 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03718392 is an A2 air-hardening tool steel flat stock bar measuring 3/8 inches thick, 1-1/4 inches wide, and 36 inches long. A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and its resistance to wear and deformation under load. This flat stock is suited for toolmakers, machinists, and die shops that need a reliable, machinable blank before heat treat. At 4.78 pounds per piece, it offers a solid, ready-to-machine section with tight tolerances held on thickness, width, and squareness.

A2 air-hardening flat stock is commonly used in the production of dies, punches, jigs, fixtures, and gauges in both job shop and production environments. Its air-hardening characteristic reduces distortion compared to oil- or water-hardening grades, making it a preferred choice for precision tooling applications. Machinists and tool and die makers typically rough machine this stock to near-net shape before sending it to heat treat, then finish grind to final dimension.

Key Features

• AISI A2 air-hardening tool steel construction for dimensional stability during hardening
• Tight thickness tolerance of plus or minus 0.001 inches for precision blanks
• Width tolerance held to plus 0.000 to 0.005 inches
• Square tolerance of plus or minus 0.003 inches across the section
• Length tolerance of plus or minus 0.250 to 0.500 inches
• Ready-to-machine flat bar format eliminates initial stock removal from round bar

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock for use in toolmaking, die making, and precision machining applications requiring AISI A2 material specification.

Installation Notes

Machining and heat treating of tool steel should be performed by qualified toolmakers or machinists familiar with A2 steel requirements. Always relieve residual stresses with a proper stress-relief cycle before finish machining. Heat treatment, including hardening and tempering, should follow the material supplier's recommended thermal cycles for A2 tool steel. Use appropriate personal protective equipment and follow shop safety protocols when cutting, grinding, or handling sharp-edged stock.
