Drill Rod Tool Steels 03718558 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03718558 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die fabrication, and precision machining applications. Measuring 0.5 inches thick, 6 inches wide, and 36 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 0.250 to 0.500 inches on length. The AISI A2 designation indicates an air-hardening, medium-alloy cold-work tool steel known for its dimensional stability during heat treatment and good wear resistance. Machinists, tool-and-die makers, and industrial fabricators work with this material to produce punches, dies, gauges, and cutting tools.

This flat stock is suited for shops and job sites requiring precision-ground tool steel in standard bar form. A2 tool steel is a common choice for cold-work tooling applications where dimensional accuracy after hardening is critical. The 0.5-inch by 6-inch cross-section supports a range of blanking, forming, and machining operations. It is appropriate for both production toolrooms and prototype die shops requiring reliable, consistent material stock.

Key Features

• AISI A2 air-hardening tool steel for stable dimensions during heat treat
• Thickness tolerance of plus or minus 0.001 inches for precision fitment
• Width tolerance of plus 0.000 to 0.005 inches for close-tolerance applications
• Square tolerance of plus or minus 0.003 inches
• 36-inch length provides full bar stock for multiple blanks per piece
• Ships as a single bar with no minimum quantity beyond one unit

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for cold-work tooling, die making, and precision machining applications requiring close dimensional tolerances.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or tool-and-die makers using appropriate personal protective equipment. A2 steel is air-hardened and should not be quenched in water or oil unless the specific heat treatment process calls for it. Consult the material data sheet for proper austenitizing and tempering temperatures before any heat treatment operation. Secure the workpiece properly before any machining or sawing operation.
