Drill Rod Tool Steels 03718202 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03718202 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, die makers, and machine shops requiring a dimensionally consistent, heat-treatable steel blank. Measuring 0.25 inches thick, 4 inches wide, and 36 inches long, this flat stock holds 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 wear resistance and toughness after air hardening, making it a reliable choice for punches, dies, forming tools, and similar precision tooling applications.

This flat stock is suited for fabrication environments where close dimensional control is required prior to heat treatment. Typical users include tool and die shops, machine shops, and maintenance facilities producing short-run or prototype tooling. The 36-inch length provides a practical starting blank for multiple parts. The air-hardening characteristic of AISI A2 tool steel reduces distortion during hardening compared to oil-hardening grades, which is especially advantageous for wider, flatter components like this one.

Key Features

• AISI A2 air-hardening tool steel for reduced distortion during heat treatment
• Thickness tolerance of plus or minus 0.001 inches for close-tolerance blanks
• Width tolerance of plus 0.000 to minus 0.005 inches
• Length tolerance of plus or minus 0.250 to 0.500 inches
• Square tolerance of plus or minus 0.003 inches
• Ready-to-machine flat stock - no additional surface prep required before rough machining

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock for use in general toolmaking, die making, and precision machining applications requiring pre-hardened or anneal-state blanks.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified toolmakers or machinists familiar with AISI A2 steel procedures. Always follow established shop safety practices when cutting, grinding, or machining tool steel, including the use of appropriate PPE. Heat treatment - including hardening and tempering - should follow the material manufacturer's published A2 tool steel processing guidelines. Consult applicable OSHA and shop safety standards when operating cutting and grinding equipment.
