Manufactured from AISI Type O1 tool steel, it measures 0.75 inches thick, 3.5 inches wide, and 18 inches long. Thickness tolerance is held to plus or minus 0.001 inches, and squareness is maintained at 0.003 inches per inch on all edges. These tight tolerances make this flat stock suitable for applications where dimensional accuracy directly affects finished tool performance. At 13.39 pounds, this is a substantial piece appropriate for heavy tooling stock requirements.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in tool and die shops, machine shops, and maintenance departments where O1 tool steel is specified for its reliable oil-hardening characteristics. Typical applications include punches, dies, gauges, jigs, fixtures, and general tooling blanks. It is supplied in the annealed condition, ready for machining prior to hardening. Machinists and toolmakers working in job shops or manufacturing facilities are the primary users of this material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel composition\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for precision layout and machining\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\u003eAll edges square to within 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition, ready for machining and subsequent oil hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 tool steel flat stock blank for use in toolmaking, die making, and precision machining applications requiring oil-hardening tool steel material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, or machining of tool steel flat stock should be performed by a qualified machinist using appropriate cutting tools rated for tool steel. Follow standard shop safety practices including eye and face protection when sawing or grinding.
