Manufactured to AISI Type O1 specifications, this flat stock measures 5\/32 inches thick, 5 inches wide, and 36 inches long, with a weight of 7.97 pounds. Thickness tolerance is held to plus or minus 0.001 inches, providing the dimensional consistency required for precision tool and die work. O1 tool steel offers good machinability in the annealed state and responds well to oil-quench hardening, making it a reliable raw material choice for shops that grind, mill, or EDM their own tooling.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for machine shops, tool and die shops, and maintenance departments that fabricate custom tooling, gauges, punches, blanking dies, and cutting tools. The 36-inch length provides enough stock for multiple parts from a single bar. Its flat, ground profile reduces setup time when close-tolerance work begins at the mill or surface grinder. This piece is sold individually and is appropriate for both one-off tooling jobs and small production runs of shop-made components.\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 held to plus or minus 0.001 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches for consistent stock removal planning\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches ensures full usable length\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e36-inch bar length yields multiple parts per piece, reducing material waste\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI Type O1 oil-hardening tool steel flat bar suitable for general toolmaking, die fabrication, and precision machining applications requiring oil-quench hardenable steel stock.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of tool steel flat stock should be performed by qualified machinists or tool and die makers familiar with O1 steel properties. Always anneal or stress-relieve the material as required before finish grinding. Use appropriate personal protective equipment when cutting or grinding tool steel.
