Drill Rod Tool Steels 86212156 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 86212156 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. This flat stock measures 3/16 inches thick, 1-1/2 inches wide, and 18 inches long, with close-tolerance grinding on all dimensions. Manufactured to AISI A2 specification, this material offers excellent dimensional stability during heat treatment, making it a reliable choice for punches, dies, and cutting tools. The piece ships ready to cut, grind, or machine to final dimensions. It weighs 1.43 pounds per piece.

A2 tool steel flat stock is used primarily in tool and die shops, machine shops, and maintenance departments where air-hardening steel is required for moderate-wear applications. The A2 grade is suited for cold-work tooling, blanking dies, forming dies, and precision gages. This bar size is a common starting blank for small die components and is appropriate for both production shops and toolroom use. Its air-hardening characteristic reduces distortion risk compared to oil-hardening grades.

Key Features

• AISI A2 air-hardening tool steel for reduced distortion during hardening
• Thickness tolerance of plus or minus 0.001 inches for close-fit toolroom applications
• Width tolerance of plus 0.000 to minus 0.005 inches
• Length tolerance of plus or minus 0.062 inches
• Square tolerance of plus or minus 0.003 inches
• Ready-to-machine flat stock - no additional surface prep required before layout

Compatibility

Designed as a standard A2 tool steel flat bar suitable for use in cold-work tooling, die making, and precision machining applications requiring AISI A2 air-hardening material.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by a qualified toolmaker or machinist familiar with air-hardening steel procedures. Follow the material supplier's recommended preheat, austenitizing, and tempering temperatures for AISI A2 before hardening. Always allow the steel to reach room temperature before precision grinding after heat treatment. Eye protection and appropriate cutting fluids should be used during machining operations.
