It measures 5 inches in diameter and 3 inches in overall length, weighing 18.1 pounds. O-1 tool steel is a general-purpose oil-hardening grade valued for its dimensional stability during heat treatment and its ability to hold a sharp edge after hardening. The decarb-free condition means the outer surface has not lost carbon content, allowing machinists and toolmakers to machine directly to finished dimensions without removing an allowance layer for decarburization. This bar ships at stock length with a length tolerance of plus 0.250 to minus 0.000 inches.\u003c\/p\u003e\u003cp\u003eThis round bar is suited for fabricating punches, dies, gauges, jigs, and cutting tools in job shop, tool room, and industrial maintenance environments. The 5-inch diameter makes it appropriate for larger die blanks and fixture components where mass and cross-sectional strength matter. Machinists working in precision tool and die, mold making, or general metalworking will find the decarb-free surface condition reduces prep steps before final machining. It is typically processed on lathes, mills, or surface grinders before hardening and tempering.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDecarb-free surface condition allows machining directly to finished size without decarburization allowance\u003c\/li\u003e\n\u003cli\u003eO-1 oil-hardening grade offers good dimensional stability and edge retention after heat treat\u003c\/li\u003e\n\u003cli\u003e5 inch diameter by 3 inch overall length suits large die blanks and fixture stock\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0.025 to plus 0.085 inches over nominal for consistent fit in tooling layouts\u003c\/li\u003e\n\u003cli\u003eWeight per foot of 70.10 pounds supports load and mass calculations for tooling design\u003c\/li\u003e\n\u003cli\u003eStock length format with plus 0.250 to minus 0.000 inch length tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O-1 oil-hardening tool steel round bar suitable for tool room and die shop applications requiring a decarb-free, oversized-diameter starting blank at 5 inches diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHandling and machining of tool steel rounds requires standard metalworking equipment including lathes and milling machines rated for alloy steel. Secure the workpiece properly in a chuck or fixture before cutting to avoid movement under load. Heat treatment — including hardening and tempering — should follow established metallurgical procedures for O-1 tool steel and be performed by qualified personnel. Eye protection and appropriate PPE are required during all machining and heat treating operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: O-1 Oil-Hardening Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.025 to plus 0.085 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 to minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 18.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight Per Foot\u003c\/strong\u003e: 70.10 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface Condition\u003c\/strong\u003e: Decarb-Free\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 20102105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: OR05.0X3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702200664370,"sku":"OR05.0X3","price":117.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc734ade68c431e7ffdf2908c56869a4_49a6e0d3-2073-4ace-a4a2-d1f41d65d3da.jpg?v=1788409895","url":"https:\/\/voomisupply.com\/products\/value-collection-or05-0x3-o-1-tool-steel-round-5x3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
