Drill Rod Tool Steels 86463957 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 86463957 is an A2 air-hardening tool steel flat stock bar sized at 1.5 inches thick, 3.5 inches wide, and 36 inches long. A2 tool steel offers excellent dimensional stability during heat treatment, making it a reliable choice for dies, punches, and precision tooling applications. The bar ships in an annealed condition, ready for machining before hardening. Machinists, tool-and-die makers, and industrial fabricators work with this stock to produce components that require good wear resistance and moderate toughness. At 54.75 pounds per bar, this is a solid, full-sized blank suitable for heavy-duty tooling work.

This flat stock is suited for tool-and-die shops, precision machining operations, and industrial manufacturing environments. A2 air-hardening steel is commonly used for blanking dies, forming dies, trim dies, shear blades, and punches where distortion during heat treat must be minimized. The 36-inch length provides enough material for most medium-sized tooling blanks without requiring additional piecing. This grade performs well in applications where D2 would be too brittle and O1 does not provide sufficient air-hardening stability.

Key Features

• A2 air-hardening tool steel - minimal distortion during hardening compared to oil-hardening grades
• Thickness tolerance of +0.010 to 0.015 inches for consistent machining stock removal
• Width tolerance of +0.010 to 0.015 inches
• Length tolerance of +0.250 to 0.500 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Single-bar minimum order quantity - no bulk commitment required

Compatibility

Designed as a standard A2 air-hardening tool steel flat bar for general tooling and die-making applications requiring AISI A2 material specification.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified tool-and-die makers or machinists familiar with A2 steel processing. Always rough-machine before hardening and leave adequate grinding stock for finish work after heat treat. Follow the material manufacturer's recommended hardening and tempering cycles for A2 tool steel. Wear appropriate PPE when cutting or grinding tool steel stock.
