It measures 3\/8 inch thick, 1-3\/4 inches wide, and 36 inches long, with a weight of 6.77 pounds per piece. O1 tool steel is known for its fine grain structure, good dimensional stability during heat treatment, and excellent machinability in the annealed state. Thickness tolerance is held to plus or minus 0.001 inches, width tolerance is plus 0.005 inches, and length tolerance is plus 0.5 inches. This stock is used by tool and die makers, machinists, and metalworking professionals who require a consistent, oil-hardening grade for precision tooling applications.\u003c\/p\u003e\u003cp\u003eO1 flat stock at this cross-section is commonly specified for punches, dies, gages, lathe centers, chuck jaws, and similar tooling where moderate toughness and good wear resistance after hardening are required. It is well suited for low-to-medium production tooling in job shops, tool rooms, and maintenance machine shops. The 36-inch bar length allows multiple blanks to be cut from a single piece, reducing material waste in typical tooling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for predictable heat treat response\u003c\/li\u003e\n\u003cli\u003eSupplied annealed for ease of machining prior to hardening\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches supports precision layout work\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\u003eSingle-piece minimum order quantity simplifies low-volume tooling projects\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 tooling, die making, and precision machining applications requiring an oil-quench grade material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and grinding of tool steel flat stock should be performed by a qualified machinist using appropriate metalworking equipment and personal protective equipment including eye and face protection. Heat treatment of O1 tool steel requires controlled furnace equipment and oil quench media; this process should be performed by personnel familiar with tool steel hardening procedures. Always allow the bar to return to room temperature before performing precision layout or final grinding operations.\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\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-3\/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: 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\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.003 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: 6.77 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: 57930\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51981851361586,"sku":"57930","price":183.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_19135390-54a5-4806-9d15-146824e5bc40.jpg?v=1789982640","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-57930-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
