O1 is a general-purpose oil-hardening tool steel known for good machinability in the annealed condition and consistent dimensional stability after heat treatment. This flat stock is manufactured to tight tolerances, making it well suited for toolmakers, machinists, and die makers who need reliable pre-sized material for dies, punches, gauges, and similar precision tooling components. At 17.85 pounds per piece, it provides substantial stock for layout-to-finish work without excess handling waste.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in machine shops, tool and die operations, and maintenance repair applications where precision steel bar stock is required. Its pre-ground flat form reduces setup time when fabricating custom tooling components such as blanking dies, forming tools, cutting blades, and fixture components. The 36-inch length accommodates a range of single-piece or multiple-piece layouts from one bar. It is appropriate for both job-shop and production toolroom environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel material specification\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for precise fits\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches, minus 0 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness of 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003ePre-sized flat bar reduces stock removal and setup time\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI O1 oil-hardening tool steel flat bar suitable for general toolroom, die-making, and precision machining applications requiring pre-ground flat stock.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate cutting fluids and feeds for tool steel. Always wear appropriate personal protective equipment when cutting or grinding. Heat treatment of O1 steel requires controlled oil quench procedures and should follow established metallurgical practice for the specific hardness requirement. Handle edges with care as ground flat stock edges can be sharp.\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: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 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, minus 0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 17.85 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: 54495\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540799324466,"sku":"54495","price":662.58,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_90aff2da-035d-4e7c-86bb-91d88ee48efb.jpg?v=1785864120","url":"https:\/\/voomisupply.com\/products\/starrett-54495-o1-tool-steel-flat-stock-7-8x2x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
