Manufactured to AISI Type O1 specification, this bar measures 3\/32 inches thick, 1 inch wide, and 18 inches long and weighs approximately 0.48 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for close-tolerance tool and die applications where dimensional consistency before hardening is critical. The stock ships in its annealed state, allowing conventional machining, grinding, and filing prior to the oil-quench hardening process.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock is used across a broad range of precision fabrication tasks including punch and die blanks, gauges, fixtures, small cutting tools, and wear parts. The 18-inch length provides enough material for multiple short blanks or a single longer workpiece. This bar is suited for job shops, tool rooms, and maintenance departments that regularly work with oil-hardening grades. It is equally appropriate for pattern makers and prototype fabricators who need a known-grade steel with predictable hardening response.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel specification for consistent heat-treat response\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for close-tolerance starting stock\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.0000 to 0.0050 inches under nominal\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches, minus 0 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch across all edges\u003c\/li\u003e\n\u003cli\u003eAnnealed condition allows machining, grinding, and filing before hardening\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 tool room, die shop, and precision fabrication applications requiring AISI Type O1 material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining should be completed before the oil-quench hardening cycle. A licensed machinist or experienced toolmaker should perform heat treatment in accordance with the material supplier recommendations for AISI O1 steel. Always use appropriate personal protective equipment when cutting or grinding tool steel. Secure the workpiece properly before any cutting operation to prevent movement and ensure dimensional accuracy.\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: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 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: 0.0000 to 0.0050 inches under nominal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 inches, minus 0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.48 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 53980\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541969568050,"sku":"53980","price":66.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_5d9f9707-e83b-4489-b6b2-1ec5cdf09c2b.jpg?v=1785888625","url":"https:\/\/voomisupply.com\/products\/starrett-53980-o1-tool-steel-flat-stock-3-32x1x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
