Manufactured to AISI Type O1 specification, this flat stock measures 1\/32 inch thick, 1 inch wide, and 18 inches long, with a thickness tolerance of plus or minus 0.001 inches. O1 tool steel is a general-purpose oil-hardening grade prized for its dimensional stability during heat treatment and its ability to hold a sharp cutting edge after hardening and tempering. The bar ships in a soft, machinable state, allowing it to be cut, drilled, or ground to final shape before heat treatment.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabricating punches, dies, gauges, blades, and small tools in both job-shop and production environments. The 1\/32-inch thickness makes it a practical choice for thin shim-style tooling blanks, wear plates, and precision spacers. Machinists and tool-and-die trades working in shops with heat-treating capability will find this bar ready to machine and finish-grind prior to the oil-quench hardening cycle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel — general-purpose grade with good wear resistance after hardening\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise blank stock\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\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch across all edges\u003c\/li\u003e\n\u003cli\u003eSoft (annealed) condition as supplied — machinable before heat treatment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat stock blank suitable for general toolmaking, die making, and precision machining applications requiring a thin, wide flat bar in annealed condition.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding of O1 tool steel should be completed before the hardening cycle. Heat treatment requires oil quenching and is typically performed by a qualified heat treater or in-shop furnace following established AISI O1 hardening procedures. Use appropriate personal protective equipment and ventilation during any cutting, grinding, or heat-treating operations. Consult applicable shop safety standards and material data sheets before processing.\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: 1\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 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: 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 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: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 53935\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544110170418,"sku":"53935","price":63.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_adf4deca-d87d-4c5f-8ecf-7d87300f5d19.jpg?v=1785924289","url":"https:\/\/voomisupply.com\/products\/starrett-53935-o1-tool-steel-flat-stock-1-32x1x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
