Manufactured to AISI Type O1 specifications, this flat stock is supplied in the annealed condition and intended for tool and die makers, machinists, and fabricators who require a reliable oil-hardening steel with consistent dimensional tolerances. Thickness tolerance holds to plus or minus 0.001 inches, making it suitable for precision tooling applications where tight stock dimensions reduce secondary grinding time. The piece weighs approximately 2.26 pounds.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock of this profile is commonly used in the fabrication of dies, punches, gauges, jigs, fixtures, and cutting tools in machine shops and tool rooms. The 36-inch length accommodates most standard blanking and layout operations without additional stock splicing. It is appropriate for both small-volume job shop use and prototype tooling work across industrial and manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel  -  consistent metallurgical properties for predictable heat treat response\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision fitment with minimal regrinding\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 0.5 inches\u003c\/li\u003e\n\u003cli\u003eSquareness: edge 0.003 inches per inch of thickness, end 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003eSingle-piece minimum order quantity  -  no bulk commitment required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat bar for use in general tool and die, fixture, and precision machining applications where AISI Type O1 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed with appropriate metal-cutting equipment by qualified machinists or toolmakers. Heat treatment  -  including oil quenching  -  should follow established procedures for AISI O1 tool steel and be performed by personnel trained in metallurgical heat treat operations. Always wear appropriate PPE when cutting, grinding, or heat treating tool steel. Verify dimensional requirements against your print tolerances before machining to finished size.\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: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\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 0.005 inches, minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: Edge 0.003 inches per inch of thickness, End 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.26 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: DRILL ROD TOOL STEELS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52111749710130,"sku":"66807","price":81.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_69c36389-815f-4b38-84f0-76bcc8417d8d.jpg?v=1790077209","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-66807-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
