Drill Rod Tool Steels 85999795 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 85999795 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, punches, and precision machining applications. Measuring 0.5 inches thick by 3.5 inches wide by 36 inches long, this flat stock is manufactured to tight dimensional tolerances, including a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.000 to 0.005 inches. At 18.05 pounds per piece, it is suited for shop stock and custom fabrication projects where dimensional consistency and material integrity are critical. Machinists, tool and die makers, and industrial fabricators are the primary installers and users of this material.

A2 tool steel flat stock is used in a wide range of toolroom and industrial manufacturing environments. Common applications include blanking dies, forming dies, trim dies, punches, gauges, and shear blades where moderate toughness combined with good wear resistance after air hardening is required. This flat bar format is a standard shop-stock shape that can be cut, milled, ground, or drilled to finished dimensions before heat treatment. It is appropriate for both short-run production tooling and prototype work in both job shop and in-house toolroom settings.

Key Features

• AISI A2 air-hardening tool steel for stable, low-distortion heat treatment
• Thickness tolerance of plus or minus 0.001 inches for precision fitment
• Width tolerance of plus 0.000 to 0.005 inches
• Length tolerance of plus or minus 0.250 to 0.500 inches
• Squareness: edge 0.003 inches and ends 0.004 inches per inch of thickness
• Standard 36-inch bar length suitable for multiple cut-to-length applications

Compatibility

Designed as a general-purpose A2 tool steel flat stock bar for toolroom, die shop, and precision machining applications requiring AISI A2 air-hardening material in flat bar form.

Installation Notes

Cutting, drilling, and grinding operations should be performed by qualified machinists or tool and die makers using appropriate machine tooling for tool steel. Heat treatment to full hardness requires air hardening per AISI A2 specifications and should be performed by a qualified heat treater. Always use proper personal protective equipment when cutting or grinding tool steel. Inspect dimensional tolerances before machining to final size to account for stock removal.
