O1 is a general-purpose oil-hardening tool steel valued for its dimensional stability during hardening, good wear resistance, and ease of machining in the annealed state. This piece measures 1\/64 inches thick, 4 inches wide, and 18 inches long, weighing approximately 0.32 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where close blank stock dimensions are critical before finish grinding or heat treat.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in the fabrication of punches, dies, gauges, jigs, fixtures, and cutting tools across job shops, tool rooms, and production environments. The 4-inch width and 18-inch length provide a workable blank for a range of small to medium tool and die applications. It ships in the annealed condition, ready for machining prior to oil-quench hardening. Licensed machinists and tool and die makers are the primary installers and fabricators for this material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel  -  stable dimensions during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for precision blank stock\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches, minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003eSquareness: edge 0.003 inches per inch of thickness, end 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition, ready for machining and subsequent oil quench hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat stock for use in general tool and die, gauge, and fixture fabrication applications where AISI Type O1 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of O1 tool steel should be performed by qualified machinists or tool and die makers familiar with oil-hardening procedures. Always follow established shop safety practices when machining tool steel, including appropriate eye protection and secure workholding. Oil quench hardening requires proper temperature control and quench media handling  -  consult a qualified heat treat specification before processing. Inspect blank dimensions before machining to account for stated tolerances.\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\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4 inches\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: plus 0.005 inches, minus 0.000 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\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 per inch of thickness, End 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 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: 809136\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52058341081394,"sku":"809136","price":191.48,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_5e4cb202-6a49-4867-9fbc-7455dd8849c3.jpg?v=1790039570","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-809136-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
