Manufactured to AISI Type O1 specification, this flat stock measures 1\/16 inch thick, 4 inches wide, and 36 inches long. Thickness tolerance is held to +\/- 0.001 inches, and squareness along all edges is controlled to 0.003 inches per inch. The piece ships at approximately 2.55 pounds. It is intended for machinists, toolmakers, and metalworking shops that require consistent, hardenable stock that can be ground and finished to tight final dimensions before or after heat treatment.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock is used in shops producing punches, dies, fixtures, gauges, blades, and general toolroom work. Its oil-hardening grade makes it suitable for applications where water-hardening or air-hardening grades are not specified. This 36-inch length provides enough material for multiple short blanks or a single longer workpiece. The 4-inch width accommodates a wide range of flat tool and die blanks without requiring initial width reduction on most toolroom jobs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for consistent hardenability\u003c\/li\u003e\n\u003cli\u003eThickness held to +\/- 0.001 inches for reliable stack and layout work\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.0000 to -0.005 inches for predictable fit in fixtures\u003c\/li\u003e\n\u003cli\u003eLength tolerance of +0.015 inches, zero minus, ensuring full usable length\u003c\/li\u003e\n\u003cli\u003eEdge squareness controlled to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eReady-to-machine condition suitable for grinding, milling, and EDM operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat stock for general toolroom, die, and fixture applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and heat treatment of tool steel flat stock should be performed by qualified machinists or toolmakers familiar with O1 oil-hardening grades. Always follow appropriate shop safety procedures when sawing or grinding tool steel, including eye and respiratory protection. Heat treatment, including hardening and tempering of O1 steel, should follow established metallurgical procedures for this grade. Consult applicable shop standards or the material supplier data sheet before heat treating.\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: 1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 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: +\/- 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: 0.0000 to -0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.015 inches, -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: 2.55 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: 54267\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538557665586,"sku":"54267","price":174.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_8b385e4f-d804-487f-9eef-530ff7446470.jpg?v=1785825053","url":"https:\/\/voomisupply.com\/products\/starrett-54267-o1-tool-steel-flat-stock-1-16x4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
