Conforming to AISI Type O1 specifications, this flat stock is used by machinists, toolmakers, and die makers who require a machinable, weldable steel that hardens predictably in an oil quench. The stock ships in an annealed condition, ready for machining and subsequent heat treatment. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for precision tooling applications where dimensional consistency before hardening matters. The piece weighs approximately 0.73 pounds.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock is a standard material in job shops, maintenance departments, and tooling rooms. It is commonly used to produce punches, dies, gauges, blades, and small fixtures. The 36-inch length suits both full-length tooling blanks and cut-to-size work. This grade is well suited to light cutting tool fabrication and general-purpose tooling where extreme abrasion resistance is not the primary requirement. It is machined with conventional HSS or carbide tooling in its annealed state prior to hardening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel  -  predictable hardening response in an oil quench\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for dimensional accuracy before heat treat\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 held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends\u003c\/li\u003e\n\u003cli\u003eShips annealed and ready for machining\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI O1 oil-hardening tool steel flat blank suitable for general toolmaking, die work, and precision machining applications requiring oil-quench heat treatment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of tool steel should be performed by qualified machinists or tool and die makers familiar with O1 processing requirements. Secure workpieces properly before cutting or grinding to prevent movement. Heat treatment, including hardening and tempering, must follow established metallurgical procedures for O1 steel and should be performed by personnel with appropriate equipment and training. Grinding after hardening produces heat that can affect surface temper if coolant flow is inadequate.\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: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/4 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: 0.73 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: 66797\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51971258384690,"sku":"66797","price":54.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_0fbbc15e-2b14-4d4b-89d8-17d7c8d4bcfb.jpg?v=1789955161","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-66797-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
