Manufactured from AISI Type O1 tool steel, this flat stock measures 1 inch thick, 3-1\/2 inches wide, and 36 inches long, weighing approximately 35.7 pounds. O1 tool steel is valued for its excellent dimensional stability during hardening, good machinability in the annealed state, and ability to hold a sharp cutting edge after heat treatment. Machinists, toolmakers, and die makers work with this material to produce punches, dies, gauges, and custom tooling components.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool and die shops, and maintenance machining departments in both industrial and commercial environments. The annealed condition allows for cutting, drilling, milling, and grinding prior to oil-quench hardening and tempering. The 36-inch length provides practical stock for cutting multiple blanks from a single piece, reducing setup time on the bandsaw or cold saw.\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\u003e1 inch thickness with a tolerance of +\/- 0.001 inches for precise stock removal planning\u003c\/li\u003e\n\u003cli\u003e3-1\/2 inch width with a tolerance of 0.000 to -0.005 inches\u003c\/li\u003e\n\u003cli\u003e36 inch length with a length tolerance of +0.015 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition, ready for machining before hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 tool steel flat stock for use in toolmaking, die making, and general precision machining applications where oil-hardening tool steel is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate cutting fluid and tooling rated for steel.
