Measuring 0.125 inches thick, 1.25 inches wide, and 36 inches long, this bar is cut to a consistent rectangular profile with tight dimensional tolerances held throughout. Thickness and squareness are controlled to plus or minus 0.001 inches, and width is held to a plus 0.000 to 0.005 inch tolerance. The AISI A2 tool steel composition provides good wear resistance and dimensional stability through the air-hardening heat treatment process, making it a reliable choice for toolroom stock.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabricating punches, dies, gauges, jigs, and fixtures in job shops, tool and die operations, and precision manufacturing environments. The 36-inch length provides a practical starting blank for layout and machining before hardening. Machinists and toolmakers working in annealed condition will find the stock dimensioned consistently enough to go directly to layout. The weight of 1.83 pounds makes it easy to handle at the bench or on a surface plate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for good wear resistance and stability after heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches held across the full length\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches ensures full usable length\u003c\/li\u003e\n\u003cli\u003e36-inch bar length suitable for multiple toolroom blanks per piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard toolroom flat stock blank compatible with conventional milling, grinding, EDM, and heat-treating processes used in A2 tool steel fabrication workflows.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or toolmakers familiar with AISI A2 specifications. Always follow the steel manufacturer's recommended annealing, hardening, and tempering temperature ranges for A2 material. Use appropriate personal protective equipment when cutting or grinding tool steel. Consult applicable shop safety codes and material data sheets before beginning thermal processing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 Tool Steel (AISI Type A2 Air-Hardening)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness (Edge)\u003c\/strong\u003e: 0.003 inches per inch, all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.83 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 54547\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542212968754,"sku":"54547","price":165.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_ff789b80-50a6-4d6a-afb8-abab72ab0bbe.jpg?v=1785895286","url":"https:\/\/voomisupply.com\/products\/starrett-54547-a2-tool-steel-flat-stock-0-125x1-25x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
