Drill Rod Tool Steels 06320055 A2 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 06320055 is an A2 air-hardening tool steel flat stock bar cut to 5/16 inches thick, 1/2 inch wide, and 18 inches long. A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and good wear resistance. This flat stock is precision-ground to close tolerances, making it well-suited for toolmakers, machinists, and die-makers who need reliable raw material for punches, dies, gauges, and similar tooling components. Weight is 0.8 pounds per piece.

A2 air-hardening flat stock is used in metalworking shops, tool-and-die operations, and maintenance departments requiring pre-cut tool steel in standard sizes. The 18-inch length is a common intermediate stock length used for fabricating short-run tooling and fixtures. Its air-hardening characteristic reduces quench distortion compared to oil- or water-hardening grades, which is a key advantage when tight dimensional control after heat treat is required.

Key Features

• A2 air-hardening tool steel per AISI designation - reduced distortion during hardening compared to oil-hardening grades
• Precision-ground flat stock with close thickness tolerance of +0.010 to 0.015 inches
• Width tolerance of +0.010 to 0.015 inches for consistent fit in tooling applications
• Length tolerance of +0.062 inches ensures usable stock after facing
• Square tolerance of +/-0.003 inches supports accurate layout and machining
• Ready-to-machine condition suitable for punches, dies, gauges, and fixture components

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat bar suitable for general cold-work tooling fabrication applications requiring precise ground stock.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified toolmakers or machinists following established shop practices. Always wear appropriate PPE when cutting, grinding, or heat-treating tool steel. Heat treatment of A2 tool steel requires controlled austenitizing and air-quench procedures - consult the material manufacturer's heat treat data sheet for proper cycles. Handle ground stock edges with care as precision-ground surfaces can be sharp.
