Starrett 57568 A2 Tool Steel Flat Stock 5/32x5x18 in

Product Description

The STARRETT 57568 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Measuring 5/32 inches thick, 5 inches wide, and 18 inches long, this flat stock is cut to size and ready for heat treatment or machining operations. A2 tool steel offers excellent dimensional stability during air hardening, moderate toughness, and good wear resistance, making it a reliable choice for punches, dies, and gauges. Tolerances are tightly held: thickness and width run +0.010 to 0.015 inches, square tolerance is +0.010 to 0.015 inches, and length tolerance is +0.25 inches. The piece weighs 4.02 pounds.

This flat stock is suited for tool and die shops, machine shops, and maintenance repair operations requiring A2 tool steel in a pre-cut flat bar form. Typical applications include blanking dies, forming dies, punches, wear plates, and precision gauging components. The 18-inch length provides enough stock for most small-to-medium tooling jobs without significant material waste. It is used by tool and die makers, machinists, and maintenance machinists in both job shop and production environments.

Installation Notes

A2 tool steel flat stock is machined and heat treated by qualified tool and die makers or machinists. Always follow established shop safety procedures when cutting, grinding, or machining tool steel, including use of appropriate personal protective equipment. Heat treatment should be performed according to AISI A2 specifications by a qualified heat treating operation. Allow stock to fully cool and inspect dimensions before finish machining to final tolerances.
