The bar measures 3\/32 inch thick, 2-1\/2 inches wide, and 18 inches long, with a thickness tolerance of plus or minus 0.001 inches for consistent stock removal and layout work. Manufactured to AISI Type O1 specification, this tool steel is well suited for applications requiring good machinability in the annealed state followed by oil-quench hardening to achieve high hardness and wear resistance. Licensed machinists, toolmakers, and die makers are the primary users of this material.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock in this size range is commonly used in job shops, tool and die facilities, and maintenance departments for fabricating custom tooling, cutting tools, gauges, jigs, and fixtures. The 18-inch length provides adequate stock for most bench-scale toolmaking tasks without excessive material waste. This bar ships in the annealed condition and requires heat treatment by qualified personnel before use in hardened tooling applications. It is suitable for both light machining operations and hand fitting prior to hardening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel in annealed flat bar form\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise stock sizing\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.0000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches, minus 0\u003c\/li\u003e\n\u003cli\u003eEdge squareness of 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eReady for machining in annealed condition prior to oil-quench hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 oil-hardening tool steel flat bar suitable for toolmaking, die making, and fixture applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate metalworking equipment. Heat treatment to harden O1 tool steel requires controlled furnace conditions and proper quenching procedure in oil — this work should be performed by personnel trained in tool steel heat treatment. Wear appropriate PPE when cutting or grinding tool steel bar stock. All heat treating operations should comply with applicable shop safety standards.\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\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2-1\/2 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: 0.0000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 inches, minus 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch, all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 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: 53984\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539363103026,"sku":"53984","price":118.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_673d6d9b-7ecf-4594-9f26-1898046468ca.jpg?v=1785838819","url":"https:\/\/voomisupply.com\/products\/starrett-53984-o1-tool-steel-flat-stock-3-32x2-1-2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
