Manufactured to AISI Type O1 specification, this flat bar measures 1\/16 inch thick, 1-1\/4 inches wide, and 36 inches long and weighs 0.8 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where close dimensional control before heat treatment is required. O1 tool steel is known for its good machinability in the annealed state and its response to oil quench hardening.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in toolroom and production machine shop environments. Typical applications include making form tools, hand scrapers, small punches, and precision fixtures. It is sold as a single 36-inch length, allowing a technician or machinist to cut it to final part length with standard metalworking equipment. The annealed condition means it can be machined, ground, or filed before hardening and tempering to final hardness.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for predictable hardening response and good wear resistance after heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for reliable fit in close-tolerance tooling layouts\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches supports consistent stock removal planning\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches ensures full usable length\u003c\/li\u003e\n\u003cli\u003eEdge squareness: all edges held within 0.003 inches per inch of width\u003c\/li\u003e\n\u003cli\u003eSingle 36-inch length ships as one piece with no minimum order beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI O1 oil-hardening tool steel flat bar suitable for general toolroom use wherever 1\/16 inch by 1-1\/4 inch cross-section flat stock is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, or machining should be performed while the stock is in the annealed condition prior to heat treatment. A licensed heat treater or qualified machinist should perform oil quench hardening and tempering to achieve target hardness. Use appropriate personal protective equipment and follow shop safety procedures when cutting or grinding tool steel. Verify final dimensions after any grinding operation before committing to heat treatment.\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: 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: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 54260\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544665882930,"sku":"54260","price":105.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_7de3fb01-3bff-4831-88ed-b7bed79dc72c.jpg?v=1785933001","url":"https:\/\/voomisupply.com\/products\/starrett-54260-o1-tool-steel-flat-stock-1-16x1-1-4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
