O1 tool steel is a cold-work, oil-quench grade known for its ease of hardening, good wear resistance, and dimensional stability through heat treat. This flat stock ships in the annealed condition and is intended for fabrication into punches, dies, gauges, cutting tools, jigs, and fixtures. Machinists, tool-and-die makers, and skilled tradespeople working in manufacturing or maintenance shops are the primary users. At 8.92 pounds per bar, this is a substantial piece suited for serious tooling applications.\u003c\/p\u003e\u003cp\u003eThis flat stock is used wherever a reliably machinable, oil-hardening tool steel is specified. Typical applications include the fabrication of blanking dies, form punches, drill jigs, and precision fixtures in job shops, maintenance departments, and production tool rooms. The annealed condition allows conventional machining before the part is hardened and tempered to final service hardness. The 36-inch length provides flexibility for multiple parts from a single bar.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel — consistent chemistry supports predictable heat-treat response\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for precision layout and fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches for controlled fit in slotted and mated applications\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches ensures full usable length per specification\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges for accurate setup and grinding reference\u003c\/li\u003e\n\u003cli\u003eAnnealed condition ready for machining prior to hardening and tempering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI O1 oil-hardening flat stock for use in general tooling, die-making, and precision fixture fabrication wherever O1 tool steel in 7\/8 inch by 1 inch cross-section is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining should be performed by qualified machinists using appropriate speeds and feeds for annealed tool steel. Hardening and tempering of O1 tool steel requires controlled atmosphere or salt-bath furnace equipment and should be performed by personnel familiar with heat-treat procedures for cold-work tool steels. Always follow shop safety protocols when cutting, grinding, or heat-treating steel bar stock. Handle with care — edges are sharp as-supplied.\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: 7\/8 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: 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.92 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: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 54492\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541260173618,"sku":"54492","price":443.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_d350c3f0-6db1-4478-9960-9be663f1215b.jpg?v=1785870960","url":"https:\/\/voomisupply.com\/products\/starrett-54492-o1-tool-steel-flat-stock-7-8x1x36","provider":"Voomi Supply","version":"1.0","type":"link"}
