Manufactured to AISI Type O1 specifications, this flat stock measures 5\/8 inches thick, 3\/4 inches wide, and 36 inches long with a finished weight of 4.78 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where tight dimensional control is required before or after heat treatment. Licensed machinists, toolmakers, and metalworking shops are the primary users of this material.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock in this size range is commonly stocked in tool rooms and machine shops for fabricating custom cutting tools, form punches, fixtures, and gauges. The 36-inch bar length allows for multiple part blanks to be cut from a single piece, reducing material waste. This stock is supplied in the annealed condition and is intended for machining to near-final dimensions prior to oil quench hardening and tempering. Edge squareness and tight thickness tolerances reduce the amount of stock removal required during setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel construction for predictable heat-treat response\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision pre-heat-treat fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches for controlled interference fits\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches, minus 0 inches for consistent blank cutting\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition, ready for machining and subsequent hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening flat stock bar suitable for general tool room, die shop, and precision metalworking applications requiring AISI Type O1 tool steel in this size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of O1 tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate carbide or high-speed tooling. All heat treatment operations, including oil quench hardening and tempering, must be carried out per established metallurgical procedures and applicable shop safety standards. Secure workpieces firmly during sawing or milling operations to prevent movement. Allow material to reach ambient temperature before taking final dimensional measurements after any thermal operation.\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\/8 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, minus 0 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: 4.78 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: 54462\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541022146866,"sku":"54462","price":283.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_6eb20210-600c-4938-ad66-105d08d6d500.jpg?v=1785867439","url":"https:\/\/voomisupply.com\/products\/starrett-54462-o1-tool-steel-flat-stock-5-8x3-4x36in","provider":"Voomi Supply","version":"1.0","type":"link"}
