Starrett 57565 A2 Tool Steel Flat Stock 5/32x2-1/2x18in

Product Description

The STARRETT 57565 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who need a reliable, dimensionally consistent material blank. The piece measures 5/32 inches thick, 2-1/2 inches wide, and 18 inches long, with a weight of 2.01 pounds. A2 tool steel offers good toughness and wear resistance with minimal distortion during air-hardening heat treatment, making it a practical choice for punches, dies, gauges, and general tooling applications. This stock arrives in the annealed condition, ready for machining before hardening.

This flat stock is suited for use in tool and die shops, maintenance machine shops, and precision fabrication environments. It is a standard choice when fabricating or repairing tooling components that require subsequent hardening and finishing. The 18-inch length provides enough material for multiple smaller blanks depending on the layout. Thickness, width, and squareness tolerances are held tight, which reduces setup and dressing time at the machine.

Key Features

Compatibility

Designed as a general-purpose A2 tool steel flat stock blank for use in tooling, die making, and precision machining applications requiring air-hardening material.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with tool steel handling. Always follow applicable shop safety practices and equipment manufacturer guidelines when cutting, grinding, or heat-treating this material. Secure the stock firmly in a vise or fixture before machining to prevent movement. Do not attempt to harden this material without proper heat-treating equipment and temperature control.
