Drill Rod Tool Steels 03719457 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03719457 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, die makers, and fabricators who require a reliable, dimensionally consistent stock material for cutting tools, dies, punches, and fixtures. This piece measures 5/16 inches thick, 1-1/2 inches wide, and 36 inches long, with a shipping weight of approximately 5.08 pounds. A2 tool steel offers excellent wear resistance and dimensional stability during heat treatment, making it a preferred choice in precision tooling applications where controlled distortion after hardening is critical.

This flat stock is suited for light to medium production tooling in machine shops, tool and die shops, and industrial fabrication environments. The 36-inch length provides enough material to cut multiple blanks for punches, blades, gauges, or custom tooling inserts. The air-hardening designation means the material reaches hardness through controlled air cooling after austenitizing, reducing the risk of cracking versus oil or water-hardened grades.

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock suitable for use in tool and die applications, punch fabrication, fixture making, and precision machining wherever AISI A2 material specification is required.

Installation Notes

Cutting and grinding of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate metalworking equipment. Heat treatment, including austenitizing and air-hardening cycles, should follow published AISI A2 guidelines and be performed in a controlled atmosphere or vacuum furnace to minimize decarburization. Always allow the material to reach ambient temperature before measuring for final dimensional verification. Use appropriate personal protective equipment when cutting, grinding, or heat treating this material.
