It is manufactured to AISI Type O1 material specification and supplied in an annealed, machinable condition ready for custom shaping before heat treatment. The stock measures 1\/32 inch thick, 6 inches wide, and 18 inches long, with tight thickness and squareness tolerances that make it suitable for jigs, fixtures, gauges, blanks, and cutting tools. At 0.96 pounds per piece, it is manageable for bench or machine shop work. Machinists and tool and die makers are the primary users of this material.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock in this size range is commonly used in job shops, toolrooms, and maintenance departments for fabricating custom tooling components. The 1\/32 inch thickness suits thin gauge tooling inserts, shim stock applications, and precision blanks that require reliable hardness response through oil quenching. The 6 inch width and 18 inch length provide sufficient material for multiple parts from a single piece, reducing material waste on small production runs.\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\u003eThickness tolerance of plus or minus 0.001 inches for close-tolerance tooling work\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\u003eSquareness tolerance of plus or minus 0.001 inches per edge, all edges within 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition for machining prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 oil-hardening tool steel flat stock for toolroom, die, and precision machining applications where AISI Type O1 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTool steel flat stock is processed by machinists and tool and die makers using conventional milling, grinding, and sawing equipment.
