Drill Rod Tool Steels 03717816 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03717816 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, punches, and precision machined components. Measuring 0.125 inches thick, 2 inches wide, and 36 inches long, this flat stock is manufactured to tight dimensional tolerances, including a thickness tolerance of plus or minus 0.001 inches and a square tolerance of plus or minus 0.003 inches. A2 tool steel offers good toughness and wear resistance with minimal distortion during air-hardening heat treatment, making it a reliable choice for toolroom applications. Machinists, tool and die makers, and fabricators commonly work with this material in both production and maintenance settings.

This flat stock is suited for annealed tool steel applications where the material will be machined to final shape and then heat treated in-house. Typical uses include blanking dies, form tools, gauges, and general-purpose tooling components. The 36-inch length provides sufficient stock for most single-piece tooling jobs. The 2-inch width reduces material removal compared to square bar when making flat or plate-style tools. AISI Type A2 designation confirms the air-hardening alloy composition, which is appropriate for applications requiring moderate impact resistance alongside good dimensional stability after hardening.

Compatibility

Designed as a general-purpose A2 tool steel flat stock for toolroom, die shop, and precision fabrication applications requiring air-hardening alloy material.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified tool and die makers or machinists familiar with AISI A2 alloy requirements. Follow established shop practices for annealed tool steel machining, including appropriate cutting speeds and coolant use. Heat treatment, including hardening and tempering, should be performed according to the material manufacturer specifications for A2 tool steel and should not be attempted without proper furnace equipment and temperature controls. Handle flat stock carefully to avoid surface damage that could affect finished part tolerances.
