Starrett 57607 A2 Tool Steel Flat Stock 0.5x1.25x18 in

Product Description

The STARRETT 57607 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who need a reliable, consistent blank for tooling, fixtures, dies, and punches. Manufactured from AISI A2 tool steel, this flat stock measures 0.5 inches thick, 1.25 inches wide, and 18 inches long, weighing approximately 3.19 pounds. A2 tool steel offers good wear resistance and dimensional stability through the air-hardening process, making it a practical choice for medium-run tooling applications where oil-hardening grades may introduce warping risk.

This flat stock is suited for machine shops, tool and die operations, and maintenance departments that fabricate or replace tooling components. The 18-inch length provides enough material for a range of small-to-medium tooling blanks without significant waste. It ships at a package quantity of one piece, with a minimum order quantity of one, making it practical for single-component jobs or prototype work in job shop environments.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with tool steel handling procedures. Follow the steel supplier and relevant industry guidelines for pre-heat, austenitizing, and air-quench cycles to achieve target hardness without cracking. Use appropriate cutting fluids and speeds for tool steel when milling, grinding, or turning this stock. Always allow the bar to reach ambient temperature before precision measurement or final grinding operations.
