Manufactured to AISI Type O1 material specification, this flat stock measures 0.125 inches thick, 3 inches wide, and 36 inches long, with a weight of 3.87 pounds per piece. O1 tool steel offers good machinability in the annealed state and hardens predictably with an oil quench, making it a standard choice for shop-floor tooling components requiring wear resistance after heat treatment.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in machine shops, tool and die operations, and fabrication environments where close-tolerance blanks are needed for punches, dies, gauges, blades, and similar components. The 36-inch length allows multiple blanks to be cut from a single piece. Thickness tolerance is held to plus or minus 0.001 inches, width tolerance is plus 0.005 inches and minus 0.000 inches, and length tolerance is plus 0.5 inches. These tolerances support direct use in precision layout and machining without additional surface grinding in most applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for predictable hardening response\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for tight dimensional control\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches and minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003eSquareness: edge 0.003 inches, end 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003e36-inch length with plus 0.5-inch length tolerance for flexible blank cutting\u003c\/li\u003e\n\u003cli\u003eWeighs 3.87 pounds per piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening flat stock blank suitable for tool and die applications, precision machining, and fabrication work requiring AISI Type O1 tool steel material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of tool steel flat stock should be performed by qualified machinists or tool and die makers. Always anneal the stock if additional machining is needed before hardening. Follow established shop safety procedures when cutting, grinding, or heat treating tool steel, including use of appropriate PPE. Consult applicable material data sheets for quench media requirements and tempering temperatures before performing any heat treat operations.\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: 3 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: 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\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\u003eWeight\u003c\/strong\u003e: 3.87 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: 66809\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51976563392818,"sku":"66809","price":120.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_68a65a8c-c923-45ff-a488-3b7ee761d248.jpg?v=1789978845","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-66809-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
