Conforming to AISI Type O1 specifications, this flat bar measures 3\/64 inches thick, 1-1\/2 inches wide, and 36 inches long, with a thickness tolerance of plus or minus 0.001 inches, a width tolerance of plus 0.005 minus 0.000 inches, and a length tolerance of plus 0.5 inches. O1 tool steel offers good machinability in the annealed state and develops high hardness after oil quench, making it a reliable choice for dies, punches, gauges, and cutting tools.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool-and-die operations, and maintenance departments that require a pre-cut, dimensionally consistent blank. The 36-inch length allows for multiple part layouts from a single piece. Edge squareness is held to 0.003 inches and end squareness to 0.004 inches per inch of thickness, which supports accurate scribing and layout work without additional dressing on most applications. Single-piece ordering is supported, making it practical for prototype and low-volume tooling work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for reliable hardness after quench\u003c\/li\u003e\n\u003cli\u003ePrecision thickness tolerance of plus or minus 0.001 inches for consistent stock removal\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 minus 0.000 inches maintains dimensional control\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches for accurate layout and fitment\u003c\/li\u003e\n\u003cli\u003e36-inch length accommodates multiple part layouts from one bar\u003c\/li\u003e\n\u003cli\u003eAnnealed condition allows machining before heat treatment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 oil-hardening tool steel flat blank for use in tool-and-die, punch, gauge, and cutting tool fabrication applications wherever AISI Type O1 material is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding of O1 tool steel should be performed in the annealed condition prior to heat treatment. Oil quenching and tempering should be carried out by a qualified heat treater or experienced toolmaker following established metallurgical practice for AISI O1. Use appropriate personal protective equipment when cutting or grinding tool steel. Verify final dimensions after any thermal processing, as distortion can occur during hardening.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI Type O1 Oil Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.005 minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: Edge 0.003 inches; End 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.73 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DRILL ROD TOOL STEELS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 860155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51971393126706,"sku":"860155","price":89.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_729bc023-8026-466a-a489-37c20d932c9d.jpg?v=1789956737","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-860155-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
