Measuring 9\/64 inches thick by 3\/4 inches wide by 18 inches long, this flat stock is held to tight dimensional tolerances: plus or minus 0.001 inches on thickness, plus 0.005 inches on width, and plus 0.250 inches on length. O1 tool steel is a widely used general-purpose oil-hardening grade valued for its dimensional stability during heat treat and its ability to achieve high surface hardness. Machinists, tool-and-die makers, and metalworking shops are the primary users.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabricating punches, dies, cutting tools, gauges, jigs, fixtures, and wear-resistant tooling components where oil quenching is the preferred hardening method. The 18-inch length makes it practical for producing multiple short blanks from a single piece. It ships at 0.55 pounds per piece, making it easy to handle at the bench or machine. Residential and light industrial machine shops, toolrooms, and trade apprenticeship programs commonly stock O1 flat bar in standard sizes like this one.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for general-purpose toolmaking applications\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches, minus 0.000 inches for consistent mating dimensions\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 sawing, milling, drilling, and grinding before hardening\u003c\/li\u003e\n\u003cli\u003eSingle-piece minimum order quantity with no multi-bar commitment required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening flat stock suitable for general toolmaking, die-making, and precision fabrication applications requiring AISI Type O1 tool steel in this cross-section.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining should be performed in the annealed state before heat treatment. Oil hardening requires controlled furnace heating followed by an oil quench; consult a qualified heat-treat technician or metallurgical reference for cycle parameters specific to O1 tool steel. Always use appropriate personal protective equipment when cutting, grinding, or heat-treating tool steel stock. Secure workpieces firmly in a vise or fixture before machining to prevent movement.\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: 9\/64 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: 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 0.250 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: 0.55 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: 810940\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51996024734002,"sku":"810940","price":37.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_3f5d03b7-e037-48be-a392-b246ff8bf758.jpg?v=1789993111","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-810940-o1-flat-stock-9-64x3-4x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
