Drill Rod Tool Steels 03718251 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03718251 is an A2 air-hardening tool steel flat stock bar cut to 5/16 inches thick, 3/4 inches wide, and 36 inches long. A2 tool steel is an oil- and air-hardening cold-work die steel valued for its dimensional stability during heat treatment and its balance of toughness and wear resistance. This flat stock is held to a thickness tolerance of plus or minus 0.001 inches and a square tolerance of plus or minus 0.003 inches, making it suitable for precision tooling applications. Machinists, tool-and-die makers, and industrial fabricators use this material for punches, dies, gauges, and similar precision components.

This flat stock is intended for cold-work tooling and precision machining applications in machine shops, tool rooms, and industrial fabrication environments. The 36-inch length provides enough stock for multiple small tooling blanks or a single long component. A2 tool steel in flat bar form is a standard choice for applications requiring good machinability in the annealed state followed by air hardening to achieve service hardness. This stock is typically purchased by toolmakers, maintenance machinists, and industrial supply operations.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified tool-and-die makers or machinists familiar with cold-work die steels. Always follow the material manufacturer's recommended annealing and hardening temperature cycles for A2 steel. Use appropriate personal protective equipment when cutting, grinding, or machining tool steel stock. Consult applicable shop safety standards before beginning any heat-treatment operations.
