O1 is a general-purpose oil-hardening tool steel (AISI Type O1) known for its machinability in the annealed state and its ability to hold a sharp edge after hardening. This flat stock is used in toolmaking, die work, jig fabrication, and precision machining applications. Machinists, toolmakers, and fabricators work with this material to produce punches, dies, blades, gauges, and fixtures where dimensional accuracy and hardenability are critical requirements.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for toolroom and production shop use across a wide range of trades and industries. The 36-inch length provides a full bar for layout and cutting to finished part dimensions. The 0.125-inch thickness and 1.5-inch width make it a practical choice for thin die plates, small blades, and precision flat tooling components. It is supplied in the annealed condition, ready for machining prior to heat treatment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel construction for reliable through-hardening in oil quench\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for precision toolmaking applications\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches, minus 0.000 inches ensures stock is never undersize\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.5 inches provides usable overage for facing or squaring operations\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\u003eSupplied in annealed condition for full machinability before hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat bar suitable for general toolroom, die shop, and precision fabrication applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining should be performed in the annealed state prior to heat treatment.
