This piece measures 0.25 inches thick, 2.5 inches wide, and 18 inches long, with a weight of 3.19 pounds. A2 tool steel offers excellent dimensional stability during air hardening and good wear resistance, making it a practical choice for punches, dies, gauges, and general toolroom applications. Thickness and squareness tolerances are held to plus or minus 0.001 inches, ensuring consistent stock removal and predictable fit-up during machining operations.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is suited for toolroom and manufacturing environments where close-tolerance blanks are required before machining, grinding, or heat treatment. Typical applications include fabricating custom dies, jigs, fixtures, and cutting tools. The 18-inch length provides useful working stock for most single-piece toolroom jobs without requiring further parting before roughing. Trade professionals working in tool and die, industrial maintenance, and precision machining will find this stock dimensionally consistent and ready for immediate layout work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI A2 air-hardening tool steel for stable, low-distortion heat treatment\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance held to plus or minus 0.001 inches for precise stock removal\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches ensures controlled fit-up\u003c\/li\u003e\n  \u003cli\u003eSquare tolerance of plus or minus 0.001 inches supports accurate layout and machining\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of plus 0.250 inches provides clean, usable ends with material for facing\u003c\/li\u003e\n  \u003cli\u003e3.19 pounds — manageable single-piece flat bar for bench and machine work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose A2 tool steel flat stock blank compatible with standard toolroom machining, grinding, and heat treatment processes used in die making, fixture fabrication, and precision maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachining and grinding of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate coolant and feeds for tool steel. Always follow established shop safety practices when cutting, grinding, or handling stock material with sharp edges.
