Manufactured to AISI Type O1 material specification, this flat stock is designed for tool and die makers, machinists, and metalworking professionals who require a reliable, hardenable steel in a ready-to-use flat bar form. O1 tool steel offers good wear resistance and dimensional stability through the oil-hardening process, making it well suited for fabricating cutting tools, punches, dies, gauges, and other precision tooling components.\u003c\/p\u003e\u003cp\u003eThis flat stock is intended for use in machine shops, toolrooms, and fabrication environments where precision ground or sawn flat bar material is required prior to hardening and finishing. The 36-inch length provides sufficient stock for multiple tool blanks per piece, minimizing waste. The close thickness and width tolerances support accurate layout and machining before the hardening cycle. It is appropriate for both small-shop and production toolmaking applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for reliable heat treatment response\u003c\/li\u003e\n\u003cli\u003eThickness of 5\/64 inches with a tight tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eWidth of 1-1\/2 inches with a tolerance of plus 0.005 inches, minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003eLength of 36 inches with a tolerance of plus 0.5 inches\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends\u003c\/li\u003e\n\u003cli\u003eWeight of 1.21 pounds per piece for easy handling and quantity planning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 oil-hardening tool steel flat bar suitable for toolmaking, die making, and precision machining applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining, grinding, and hardening of O1 tool steel flat stock should be performed by qualified machinists or tool and die makers familiar with tool steel heat treatment procedures. Follow the material manufacturer's recommended oil-quench hardening and tempering parameters for AISI O1 tool steel. Use appropriate personal protective equipment when cutting, grinding, or heat treating. Ensure all machining is complete or near-complete before the hardening cycle, as post-hardening material removal is significantly more difficult.\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\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/2 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: plus 0.005 inches, minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: Edge 0.003 inches, End 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.21 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: DRILL ROD TOOL STEELS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 809941\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51972360438066,"sku":"809941","price":76.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_8617cbef-48f1-4f65-a1c1-491fae381d3c.jpg?v=1789966873","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-809941-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
