Manufactured from AISI Type O1 tool steel, this flat stock measures 1-1\/4 inches thick, 4 inches wide, and 36 inches long and weighs 51 pounds. O1 is a general-purpose oil-hardening tool steel known for its good machinability in the annealed state and its ability to hold a sharp edge after heat treatment. Machinists, tool and die makers, and industrial fabricators work with this material to produce punches, dies, gauges, and custom tooling components requiring tight dimensional control.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for shop floor and toolroom environments where close-tolerance raw material stock is required before hardening and finishing. The 36-inch length provides sufficient stock for multiple tooling blanks. The 1-1\/4-inch thickness and 4-inch width accommodate a wide range of die and punch profiles. It is appropriate for both light production toolrooms and prototype or job-shop environments. Machinists typically rough-machine this stock in its annealed state before oil quenching to achieve the desired hardness.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for reliable heat-treat response\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal calculations\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches for predictable fit in fixtures\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches, minus 0 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness of 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging with no minimum order quantity above one piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard raw material flat stock for toolmaking, die making, and precision machining applications requiring AISI Type O1 oil-hardening tool steel in a 1-1\/4 by 4 by 36 inch form factor.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis is raw annealed tool steel stock intended for machining prior to heat treatment. Handle with appropriate lifting equipment given the 51-pound weight. Machine in the annealed state using conventional milling, drilling, or grinding equipment before oil quenching.
