Measuring 1\/8 inch thick, 7 inches wide, and 36 inches long, it is manufactured to AISI Type O1 specification and holds tight dimensional tolerances throughout. Thickness tolerance is plus or minus 0.001 inches, length tolerance is plus 0.015 inches, and width tolerance runs from 0.000 to minus 0.005 inches. Squareness on all edges is held to 0.003 per inch. At 8.94 pounds, this flat bar is stocked in a single-piece quantity for job-specific cutting and shaping needs. Tool and die makers, machinists, and metalworking shops are the primary users of this material.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock in this size range is commonly used in the fabrication of dies, jigs, fixtures, gauges, and cutting tools. The 7-inch width and 36-inch length provide sufficient stock to cut multiple blanks or fabricate larger tooling components from a single piece. O1 tool steel responds well to conventional oil-hardening heat treatment, making it a practical choice for shops that perform in-house heat treating. This flat stock is suited for both prototype and production tooling applications in machine shops and manufacturing facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel construction\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eSquareness maintained at 0.003 per inch on all edges\u003c\/li\u003e\n\u003cli\u003e36-inch length provides ample stock for multiple workpiece cuts\u003c\/li\u003e\n\u003cli\u003e7-inch width accommodates wide-format die and fixture blanks\u003c\/li\u003e\n\u003cli\u003eSingle-piece minimum order quantity for job-specific procurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat bar suitable for general toolmaking, die making, and precision machining applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed using equipment rated for hardened or semi-hard ferrous materials, with appropriate cutting fluids applied to manage heat buildup. Heat treating to final hardness should follow AISI O1 oil-quench procedures and is typically performed by a qualified heat treat technician or toolroom machinist. Always wear appropriate personal protective equipment when cutting, grinding, or machining tool steel. Consult applicable shop safety standards and material data sheets before processing.\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 Type O1 Oil Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7 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: 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.003 per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.94 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: 54313\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540657373490,"sku":"54313","price":572.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_05e2e011-1392-4e80-9535-b9d2eb996a20.jpg?v=1785861090","url":"https:\/\/voomisupply.com\/products\/starrett-54313-o1-tool-steel-flat-stock-1-8x7x36","provider":"Voomi Supply","version":"1.0","type":"link"}
