Manufactured to AISI Type O1 specification, this flat stock is suited for toolmakers, machinists, and die makers who require tight dimensional tolerances and predictable heat-treat response. Thickness tolerance is held to plus or minus 0.001 inches, making it a reliable choice for precision tool and die applications where stock removal and finish grinding are part of the workflow. The bar ships at approximately 1.2 pounds and is ready for layout, machining, and subsequent oil-hardening heat treatment.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock of this profile is commonly used in the fabrication of punches, dies, gauges, jigs, fixtures, and blades in both job-shop and production toolroom environments. The 36-inch length provides enough material for multiple short workpieces or a single long component. Machinists typically rough-cut to near-net shape, finish grind, then harden and temper to the desired hardness for the application. This stock is appropriate for low-to-medium production tooling where oil-quench hardenability and good wear resistance are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for predictable, controlled heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for minimal stock removal before finish grinding\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches ensures consistent fit in toolroom setups\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches gives full usable stock on every bar\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch across all edges\u003c\/li\u003e\n\u003cli\u003eSingle 36-inch bar format suits both single-piece and multi-piece toolroom jobs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat bar suitable for general toolroom, die-making, and precision machining 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 using appropriate metalworking equipment and cutting fluids. Secure the workpiece firmly before any cutting or grinding operation. Heat treatment, including oil quenching and tempering, should follow established metallurgical procedures for AISI O1 tool steel and be performed by personnel experienced with tool steel heat treatment. Allow the bar to reach room temperature before taking final dimensional measurements.\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: 5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 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\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: 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: 54325\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544049025330,"sku":"54325","price":118.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_ccf41cac-d88a-47d9-9cfc-5d88885c209e.jpg?v=1785923277","url":"https:\/\/voomisupply.com\/products\/starrett-54325-o1-tool-steel-flat-stock-5-32x3-4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
