Manufactured to AISI Type O1 specification, this flat stock is sized and toleranced for precision toolmaking, die work, punches, and general tool room applications. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where dimensional accuracy before hardening is critical. At 2.58 pounds, it is a manageable single-piece stock that machinists, tool and die makers, and industrial maintenance trades use to fabricate or replace tooling components.\u003c\/p\u003e\n\u003cp\u003eO1 tool steel flat stock is used in job shops, tool rooms, and maintenance departments for fabricating punches, dies, gauges, bushings, and custom cutting tools. The oil-hardening characteristic of AISI O1 means it reaches full hardness with minimal distortion during the quench cycle, making it a preferred material when close-tolerance finished dimensions are required after heat treatment. This piece is suited for low-to-medium production tooling in both light industrial and heavy manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI Type O1 oil-hardening tool steel for minimal distortion during heat treatment\u003c\/li\u003e\n  \u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for precision stock preparation\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\u003c\/li\u003e\n  \u003cli\u003eSquareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends\u003c\/li\u003e\n  \u003cli\u003eSingle-piece quantity available with no minimum order beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard AISI Type O1 oil-hardening tool steel flat bar suitable for general tool room stock applications requiring precision-toleranced pre-hardened flat material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed with tooling rated for hardened or semi-hardened steel. Heat treatment and oil quenching should be carried out by qualified personnel following established metallurgical procedures for AISI O1 tool steel. Always allow the workpiece to reach ambient temperature before taking final measurements to verify dimensional compliance with tolerance requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 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 0.25 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\u003eWeight\u003c\/strong\u003e: 2.58 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 66777\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51984982278450,"sku":"66777","price":90.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_60c7521f-70a0-47eb-9e98-74d1acdadcc2.jpg?v=1789985137","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-66777-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
