It measures 1\/8 inch thick, 1-1\/4 inches wide, and 36 inches long, and is manufactured to AISI Type O1 material specification. Thickness tolerance is held to +\/- 0.001 inches, making it suitable for applications where close dimensional control is required before heat treating. At 1.91 pounds per piece, it is a manageable length for bench and shop use. Machinists, tool and die makers, and skilled tradespeople work with this stock to produce punches, dies, gauges, and similar hardened tooling components.\u003c\/p\u003e\n\u003cp\u003eO1 tool steel flat stock is a standard choice in job shops, maintenance departments, and tool rooms handling light- to medium-duty tooling work. This bar is supplied in the annealed condition, allowing it to be machined or ground to final dimensions before oil quench hardening. It is appropriate for producing small to mid-size flat tooling components in both one-off and short-run production scenarios. The 36-inch length allows multiple blanks to be cut from a single piece, reducing material waste on typical tooling projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI Type O1 oil-hardening tool steel for reliable heat-treat response\u003c\/li\u003e\n  \u003cli\u003eTight thickness tolerance of +\/- 0.001 inches suits precision tooling work\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of 0.0000 to 0.0050 inches for consistent stock sizing\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of +0.015 inches ensures no undersize pieces\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 grinding prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat bar for use in tool and die making, fixture fabrication, and general precision tooling applications requiring an oil-quench-hardening grade of tool steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCutting and machining of tool steel flat stock should be performed with appropriate metalworking equipment and tooling rated for hardened or semi-hard steel grades. Work in the annealed condition prior to heat treatment to maintain dimensional accuracy. Oil quench hardening should be performed by personnel familiar with heat-treating procedures for O1 tool steel to avoid warping or cracking. Follow applicable shop safety practices when cutting, grinding, or handling raw tool steel stock.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/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 0.0050 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: Edge: All 0.003 inches per inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.91 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 54302\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538795987250,"sku":"54302","price":130.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_ca6b3bae-8871-4fcb-b4cf-6d9af065a292.jpg?v=1785826839","url":"https:\/\/voomisupply.com\/products\/starrett-54302-o1-tool-steel-flat-stock-1-8x1-1-4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
