O1 is a general-purpose tool steel known for good machinability in the annealed state and reliable hardening response when quenched in oil. This flat stock is pre-dimensioned to close tolerances, making it ready for layout, machining, and fabrication of cutting tools, punches, dies, gauges, and jigs. It is supplied in the annealed condition. Machinists, toolmakers, and die makers are the primary users. At 2.55 pounds per piece, the bar is manageable for bench and mill work.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for tool and die shops, machine shops, and maintenance departments requiring reliable O1 material for short-run tooling and fixture work. Typical applications include blanks for hand reamers, taps, drill blanks, woodworking tools, and small dies. The annealed condition allows conventional milling, turning, and grinding before hardening. No compatibility with specific machine models is implied; this is a raw material stock item used wherever O1 tool steel flat bar is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI O1 oil-hardening tool steel — good machinability and predictable hardening response\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for close-tolerance blanks\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches\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 on all edges\u003c\/li\u003e\n\u003cli\u003eSupplied annealed — ready for machining prior to heat treatment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat stock blank for use wherever AISI Type O1 material in a 0.25 inch by 2 inch cross-section is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis is a raw material stock item worked by toolmakers and machinists using conventional milling, surface grinding, and sawing equipment. Secure the bar firmly in a vise or fixture before machining. When heat treating, follow the oil-quench procedure appropriate for AISI O1 tool steel and use proper personal protective equipment during quenching operations. Hardened pieces should be tempered promptly after quenching to relieve internal stress.\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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 inches\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: 0.000 to minus 0.005 inches\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: 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: 54076\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544083759410,"sku":"54076","price":139.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_7aa4bce6-e2f3-46a0-a79e-a9824f8ac434.jpg?v=1785923843","url":"https:\/\/voomisupply.com\/products\/starrett-54076-o1-tool-steel-flat-stock-1-4x2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
