Produced to AISI A2 specifications, this flat stock measures 3\/16 inches thick, 1-1\/4 inches wide, and 18 inches long, and weighs 1.19 pounds. A2 tool steel is known for its good wear resistance and dimensional stability during heat treatment, making it a practical choice for punches, dies, gauges, and similar precision tooling applications.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for machine shops, tool rooms, and fabrication environments handling light to medium tooling work. The 18-inch length accommodates a wide range of blanking and machining operations without requiring initial resizing. Its air-hardening designation means it can be hardened in still or forced air, reducing distortion compared to oil-hardening grades. Trade professionals in precision machining and die work will find this bar ready for layout, milling, and grinding operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for reduced distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of +\/- 0.001 inches for consistent stock removal calculations\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of +0.000 to +0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of +0.250 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of +\/- 0.001 inches\u003c\/li\u003e\n\u003cli\u003eReady-to-machine flat stock at 1.19 pounds per piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock suitable for punches, dies, gauges, and general precision tooling fabrication where air-hardening grades are specified.\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 A2 material requirements. Always follow proper personal protective equipment protocols when cutting or grinding tool steel. Heat treatment, including hardening and tempering, should be performed according to the material specification and applicable shop procedures. Allow material to reach ambient temperature before taking final dimensional measurements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: +\/- 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: +0.000 to +0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: +\/- 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.19 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: 54611\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540852146482,"sku":"54611","price":123.01,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_875bbfe9-74cd-4159-9bc4-a42e3b0d26eb.jpg?v=1785865039","url":"https:\/\/voomisupply.com\/products\/starrett-54611-a2-tool-steel-flat-stock-3-16x1-1-4x18in","provider":"Voomi Supply","version":"1.0","type":"link"}
