O1 is a general-purpose tool steel alloy known for good wear resistance, ease of machining in the annealed state, and consistent response to oil-quench hardening. This flat stock ships in the annealed condition, ready for machining, grinding, and heat treatment by toolmakers, machinists, and die makers. Tight dimensional tolerances  -  plus or minus 0.001 inches on thickness  -  make it suitable for tooling, jigs, fixtures, blades, and punches where dimensional accuracy before hardening is critical.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is used in machine shops, tool and die operations, and maintenance departments that fabricate or replace small cutting tools, form dies, and precision fixtures. The 18-inch length is a practical stock length for short-run tooling projects. At 0.81 pounds, individual pieces are easy to handle for bench work. Both manual machinists and CNC shops use O1 flat bar as a cost-effective alternative to higher-alloy tool steels when oil-quench hardening and moderate toughness meet the job requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI Type O1 oil-hardening tool steel  -  uniform response to oil-quench heat treatment\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision pre-machined fits\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of plus 0.005 inches, minus 0.000 inches\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of plus 0.25 inches, minus 0.000 inches\u003c\/li\u003e\n  \u003cli\u003eSquareness: edge 0.003 inches, end 0.004 inches per inch of thickness\u003c\/li\u003e\n  \u003cli\u003eAnnealed condition supports drilling, milling, and grinding before hardening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat bar for use in general toolmaking, die making, fixture fabrication, and precision machining applications where AISI Type O1 material specification is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachining and heat treatment of tool steel should be performed by qualified toolmakers or machinists familiar with O1 hardening procedures. Secure stock firmly in a vise or fixture before cutting or grinding to prevent movement and maintain dimensional accuracy. Protect finished ground surfaces from corrosion during storage  -  O1 steel is not stainless and will rust if left uncoated. Follow established heat treatment practices for O1 including proper soak temperature, oil quench, and tempering cycles appropriate to the intended application hardness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 5\/32 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: 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: 0.81 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 57730\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52019716686130,"sku":"57730","price":44.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_1a8dbd68-dfc2-4cf6-a386-1ce9b72868c8.jpg?v=1790011201","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-57730-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
