It measures 0.25 inches thick, 14 inches wide, and 18 inches long, and weighs 18.04 pounds. O1 tool steel is a versatile, oil-quenched grade known for its dimensional stability during heat treatment, making it a standard choice for dies, punches, gauges, and cutting tools. Machinists, toolmakers, and metalworking shops stock this material as a ready-to-machine blank for precision tooling and fixture applications.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool and die operations, and maintenance machine shops requiring a reliable, pre-cut O1 tool steel blank. The generous 14-inch width and 18-inch length provide enough material to lay out multiple tooling components from a single piece. Its tight thickness and squareness tolerances make it appropriate for applications where dimensional accuracy before heat treat is critical.\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\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal during machining\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches, minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches, minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance: edge 0.003 inches, end 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.003 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-format O1 oil-hardening tool steel flat stock blank suitable for general toolmaking, die making, and precision machining applications requiring AISI Type O1 material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and heat treating of tool steel should be performed by qualified machinists or toolmakers familiar with O1 oil-hardening procedures. Always wear appropriate PPE when machining or cutting tool steel stock. Follow established heat treatment procedures for O1 grade, including proper preheat, hardening temperature, and oil quench, using equipment rated for the application. Allow material to reach ambient temperature before final dimensional inspection.\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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 18.04 pounds\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 0.005 inches, minus 0.000 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 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: Edge 0.003 inches; End 0.004 inches per inch of thickness\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: DRILL ROD TOOL STEELS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 57750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52093828497714,"sku":"57750","price":288.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_6391dd67-ccc9-4579-9b64-c53a2c3b89f3.jpg?v=1790064880","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-57750-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
