O1 tool steel is a general-purpose, oil-quenched cold-work steel widely used in toolmaking, die-making, and precision machining applications where dimensional stability and good wear resistance after hardening are required. This flat stock ships in the annealed condition and is ready for machining, grinding, and heat treating. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for precision tool and die work where tight dimensional control is critical. Machinists, toolmakers, and die makers are the primary users of this material.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabricating punches, dies, gauges, blanking tools, knives, and similar toolroom components in both job shop and production environments. The 3\/8 inch by 7 inch by 18 inch size is a practical off-the-shelf dimension for medium-format tooling blanks that require further machining or grinding to final size. This bar is appropriate for job shops, tool and die facilities, and maintenance departments requiring a reliable O1 flat stock in a standard size without committing to full-length bar stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for good wear resistance and dimensional stability after heat treatment\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for precision toolroom applications\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches, minus 0.000 inches for predictable material allowance\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches for safe saw-cut oversize delivery\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 straightforward machining and grinding before oil-quench hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard off-the-shelf O1 oil-hardening tool steel flat stock for use in general toolmaking, die-making, and precision machining applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and heat treating of tool steel should be performed by qualified machinists or toolmakers following established shop safety practices. Always power down and lock out any machine tool before securing the workpiece. Oil-hardening heat treatment requires a controlled furnace and an appropriate quench oil tank  -  follow the steel manufacturer's published heat treat data for O1 for austenitizing temperature and soak time. Wear appropriate PPE including heat-resistant gloves and face protection during quenching 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\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7 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 0.25 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\u003eWeight\u003c\/strong\u003e: 13.53 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: 57771\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51985423040818,"sku":"57771","price":271.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_24265501-3499-4ca7-85a1-413c97265971.jpg?v=1789985416","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-57771-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
