It measures 1\/16 inch thick, 1-3\/4 inches wide, and 36 inches long, and is manufactured to AISI Type O1 tool steel specification. O1 is a widely used oil-hardening grade valued for its dimensional stability during heat treatment, good wear resistance after hardening, and ease of machining in the annealed state. Thickness tolerance is held to plus or minus 0.001 inches, making this stock suitable for applications where close dimensional control before final grinding is required.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is used in tool and die shops, maintenance machining operations, and precision fabrication environments. Typical applications include making punches, dies, gauges, fixtures, and cutting tools. The 36-inch length allows a single bar to yield multiple blanks. It is supplied in the annealed condition, so it can be machined, drilled, and shaped before hardening. Trade professionals in tool rooms and job shops handling precision metalwork are the primary users of this material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI Type O1 oil-hardening tool steel — stable dimensions through heat treatment cycle\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of plus or minus 0.001 inches for close-tolerance blank work\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of plus 0.015 inches, minus 0 inches — never undersized in length\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches for consistent fit in die sets and fixtures\u003c\/li\u003e\n  \u003cli\u003eEdge squareness held to 0.003 inches per inch across all edges\u003c\/li\u003e\n  \u003cli\u003e36-inch full bar length provides material for multiple part blanks from a single piece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose O1 tool steel flat bar for use in any tool room, die shop, or precision machining application requiring AISI Type O1 oil-hardening stock in 1\/16 x 1-3\/4 x 36 inch bar form.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis material is supplied in the annealed state and should be machined to final form before heat treatment. Oil hardening requires controlled heating and quenching in oil — follow established heat treating procedures and applicable shop safety protocols for open quench operations. Use appropriate personal protective equipment when handling hot stock or quench oil. Cut to length with a bandsaw, cold saw, or abrasive cutoff wheel suited for tool steel.\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: 1\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-3\/4 inches\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, minus 0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.12 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 54262\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544556306738,"sku":"54262","price":132.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_a1ee151c-b111-4a92-8a1c-8a120644c7fa.jpg?v=1785929764","url":"https:\/\/voomisupply.com\/products\/starrett-54262-o1-tool-steel-flat-stock-1-16x1-3-4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
