Drill Rod Tool Steels 85997559 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85997559 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Cut to 5/16 inches thick, 3 inches wide, and 72 inches long, this flat stock is manufactured to tight dimensional tolerances: plus or minus 0.001 inches on thickness, plus 0.000 to 0.005 inches on width, and plus or minus 1 inch on length. AISI A2 tool steel offers excellent dimensional stability during air hardening and is a standard material for blanking dies, forming tools, and gauges. Machinists and tool and die makers source this stock for annealed-condition work before heat treatment.

This flat stock is suited for fabrication of precision tooling components in job shops, tool rooms, and manufacturing facilities. Typical applications include punch and die sets, shear blades, lathe centers, master gauges, and forming rolls. The 72-inch length allows multiple parts to be laid out and cut from a single bar, reducing material waste. The annealed condition of A2 flat stock allows conventional machining prior to hardening and tempering to final hardness.

Key Features

• AISI A2 air-hardening tool steel - stable dimensions during heat treat, low distortion
• Thickness tolerance of plus or minus 0.001 inches for precision fit-up
• Width tolerance of plus 0.000 to 0.005 inches
• Length tolerance of plus or minus 1 inch on 72-inch bar
• Squareness: edge 0.003 inches and ends 0.004 inches per inch of thickness
• Full 72-inch bar length supports multi-part layout and cut-off

Compatibility

Designed as a standard AISI A2 tool steel flat stock suitable for general toolmaking, die making, and precision machining applications requiring air-hardening tool steel in flat bar form.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate metal-cutting equipment. Follow all shop safety practices when sawing or grinding, including eye protection and proper workholding. Heat treatment - hardening and tempering - should be performed according to AISI A2 specifications and should not be attempted without appropriate furnace equipment and temperature controls. Allow stock to reach ambient temperature before taking final dimensional measurements.
