Manufactured to AISI Type O1 specification, it measures 3\/64 inches thick, 3 inches wide, and 36 inches long, weighing 1.45 pounds. O1 tool steel offers good wear resistance and dimensional stability during oil-quench hardening, making it a reliable choice for flat tooling components, gauges, and punches. Machinists, tool-and-die makers, and fabricators work with this material in both shop and production environments.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for applications requiring precise tolerances in the annealed condition before hardening. Typical uses include fabricating blanks for cutting tools, forming dies, wear plates, and fixtures. The stock arrives in a machinable annealed state, ready for profiling, drilling, or grinding prior to heat treatment. It is appropriate for small-batch toolroom work as well as single-piece prototype fabrication, and the 36-inch length provides sufficient stock for multiple blanks from a single bar.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for predictable heat-treat response\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for consistent stock removal\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches, minus 0.000 inches maintains oversize-safe dimensioning\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.5 inches ensures full usable length\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\u003eAnnealed condition allows machining and grinding before oil-quench hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 oil-hardening tool steel flat stock suitable for toolroom, die shop, and precision fabrication use where AISI Type O1 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and drilling should be performed in the annealed state prior to heat treatment. Heat treatment of O1 tool steel involves oil quenching and should be performed by a qualified heat treater following AISI O1 hardening guidelines. Use appropriate personal protective equipment when cutting or grinding tool steel. Secure stock firmly in a vise or fixture before any machining operation.\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\/64 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\u003eWeight\u003c\/strong\u003e: 1.45 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 0.5 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\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: 860188\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51976811184434,"sku":"860188","price":157.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_1ae7f8e1-7bd4-49ea-ae13-280f8f101ae0.jpg?v=1789979078","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-860188-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
