O1 is an AISI-specified oil-hardening tool steel valued for its dimensional stability during heat treat and its ability to hold a sharp, durable edge after hardening. This flat stock ships in an annealed, machinable condition and is intended for toolmakers, machinists, and die makers who need precise, ready-to-use bar stock for cutting tools, punches, dies, gauges, and fixtures. At 1.94 pounds per piece, it is a practical single-piece stock length for most bench and machine shop applications.\u003c\/p\u003e\u003cp\u003eO1 oil-hardening flat stock is a standard material for tool and die shops, job shops, and maintenance departments in manufacturing environments. It is used to fabricate custom cutting tools, form dies, jigs, and wear components where moderate toughness and good machinability in the annealed state are required. The 36-inch length suits both full-length tool blanks and multiple shorter pieces cut from a single bar. This stock is appropriate for in-house tooling fabrication by qualified machinists and toolmakers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for consistent response to oil-quench heat treatment\u003c\/li\u003e\n\u003cli\u003eAnnealed condition allows machining, grinding, and drilling before hardening\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for precise fitment in tooling applications\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches to zero for controlled stock removal\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.5 inches ensures full usable length on every piece\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\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 oil-hardening tool steel flat bar suitable for tool and die fabrication, punch and die sets, gauges, fixtures, and other precision tooling applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining, grinding, and heat treatment of tool steel should be performed by qualified machinists or toolmakers familiar with O1 oil-hardening procedures. Eye protection, appropriate cutting fluids, and properly dressed grinding wheels are standard for tool steel stock work. Oil quenching and tempering operations should follow established metallurgical practices for AISI O1 and must be performed in a controlled environment to avoid cracking or distortion. Handle bar stock carefully on long lengths to avoid bending or surface damage before machining.\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\/16 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: 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: 1.94 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: 66817\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52086436036914,"sku":"66817","price":79.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_962f12a0-206d-4ab9-ad20-88a2ecd3d6f1.jpg?v=1790059684","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-66817-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
