Manufactured to AISI Type O1 material specification, this flat stock measures 9\/16 inches thick, 2 inches wide, and 36 inches long, and weighs approximately 11.47 pounds. Thickness tolerance is held to +\/- 0.001 inches, making it suitable for applications that demand close dimensional control before hardening. Machinists, tool and die makers, and metalworking shops rely on O1 flat stock as a starting blank for punches, dies, gauges, and cutting tools.\u003c\/p\u003e\u003cp\u003eO1 tool steel is a general-purpose oil-hardening grade well suited to both hand and machine operations before heat treatment. This bar is used in job shops and production toolrooms for fabricating flat tooling components that require moderate wear resistance after hardening and tempering. Its consistent cross-section and tight tolerances reduce setup time and material removal when precision blanks are needed. The 36-inch length provides flexibility for cutting multiple shorter blanks from a single piece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel — machines well in the annealed state before heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of +\/- 0.001 inches for precise pre-hardening dimensions\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to -0.005 inches ensures the bar does not exceed nominal width\u003c\/li\u003e\n\u003cli\u003eLength tolerance of +0.015 inches with no undercut\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e36-inch bar length suitable for cutting multiple tool blanks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening flat stock bar for use in general toolroom, die making, and precision machining applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eO1 tool steel flat stock is worked by qualified machinists and tool and die makers using conventional milling, grinding, and sawing equipment in the annealed condition. Heat treatment — including hardening and tempering — should be performed by personnel familiar with tool steel procedures and applicable shop safety standards. Always allow the bar to reach a stable temperature before precision grinding to avoid dimensional changes from thermal expansion. Wear appropriate PPE when cutting or grinding tool steel.\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: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.47 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: +\/- 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: 0.000 to -0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +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\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: 54460\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542039888178,"sku":"54460","price":468.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_224274a3-a5d7-4148-af99-ddee9b258350.jpg?v=1785890335","url":"https:\/\/voomisupply.com\/products\/starrett-54460-o1-tool-steel-flat-stock-9-16x2x36","provider":"Voomi Supply","version":"1.0","type":"link"}
