Conforming to AISI Type O1 material specification, it measures 3\/16 inches thick, 6 inches wide, and 18 inches long, with a weight of 5.8 pounds. O1 tool steel offers good machinability in the annealed condition and develops a hard, wear-resistant surface after oil-quench heat treatment. This flat stock is supplied to tight dimensional tolerances, making it suitable for applications where precise stock sizing reduces downstream grinding or machining time. Machinists, toolmakers, and fabricators working in job shop or production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited to toolroom and general metalworking applications where annealed O1 stock is required before hardening and tempering. Typical uses include blanks for die plates, stripper plates, punches, gauges, and custom tooling components. The 6-inch width and 18-inch length provide a useful starting blank size for medium to large tool profiles without requiring initial saw reduction. The annealed condition allows conventional milling, drilling, and grinding prior to the oil-hardening heat treatment cycle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel  -  machines well in the annealed state and responds predictably to oil-quench heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches ensures consistent stock sizing for precision tooling applications\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches \/ minus 0.000 inches maintains minimum material for finish grinding\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches provides adequate material for facing or squaring the ends\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\u003eAt 5.8 pounds, the bar size is manageable for bench setups and standard mill or surface grinder fixturing\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 blank suitable for toolroom, die shop, and precision fabrication applications requiring AISI Type O1 material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eO1 tool steel flat stock is worked by qualified machinists and toolmakers using conventional milling, grinding, and drilling equipment. Ensure the workpiece is properly fixtured and deburred before layout and machining operations begin. Heat treatment  -  annealing, hardening, and tempering  -  should be performed by personnel experienced with tool steel heat treatment procedures and appropriate quench media. Follow applicable shop safety practices when handling sharp-edged flat stock and during all heat treatment operations.\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: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.8 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 0.25 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\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: 57739\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52006384435506,"sku":"57739","price":149.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_5e88750d-b488-48ce-93fc-9fbad04eab84.jpg?v=1790000943","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-57739-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
