Drill Rod Tool Steels 85998714 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85998714 is an A2 air-hardening tool steel flat stock bar sized at 2 inches thick, 2 inches wide, and 18 inches long. A2 tool steel is an air-hardening, cold-work die steel known for its good dimensional stability during heat treatment and strong wear resistance. This bar is held to tight tolerances: plus or minus 0.001 inches on thickness, plus or minus 0.003 inches on squareness, and plus 0.000 to 0.005 inches on width. It is used by tool-and-die makers, machinists, and industrial fabricators who need stock material for punches, dies, gauges, and cutting tools.

This flat stock is suited for cold-work tooling applications in job shops, tool rooms, and manufacturing environments. The A2 air-hardening specification means the material can be hardened without quenching in oil or water, which reduces distortion and cracking risk during heat treatment. The 18-inch length makes it practical for a range of die and punch blank applications. Machinists and tool makers working to close tolerances will find the controlled width, thickness, and squareness specs directly usable from stock.

Key Features

• A2 air-hardening tool steel for reduced distortion during heat treat
• Thickness held to plus or minus 0.001 inches tolerance
• Width tolerance of plus 0.000 to 0.005 inches for precise fitment
• Squareness tolerance of plus or minus 0.003 inches
• Length tolerance of plus or minus 0.062 inches on 18-inch bar
• Ready-to-machine flat stock for punches, dies, and gauges

Compatibility

Designed as a standard A2 tool steel flat stock bar conforming to AISI Type A2 air-hardening material specification, suitable for cold-work tooling applications where controlled tolerances and air-hardening properties are required.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified tool-and-die makers or machinists familiar with cold-work die steels. Always follow the material manufacturer's recommended preheat, austenitizing, and air-cooling procedures for A2 steel to achieve target hardness without cracking. Grinding and EDM operations should be completed after hardening and before finish sizing to final tolerance. Use appropriate personal protective equipment when machining or grinding tool steel stock.
