O-1 tool steel is a general-purpose, oil-hardening grade known for good machinability, dimensional stability during heat treatment, and the ability to hold a fine edge after hardening. The decarb-free condition means the outer surface retains full carbon content, eliminating the need to machine away a decarburized layer before use. This bar is suited for machinists, toolmakers, and die shops working to close tolerances on tool and die components.\u003c\/p\u003e\u003cp\u003eThis round is a stock-length piece intended for shop use in fabricating punches, dies, gauges, bushings, and similar tooling components. The 3.5-inch diameter and 1-inch length make it practical for facing, boring, or turning operations where a short, large-diameter blank is required. It is appropriate for job shops, maintenance departments, and production toolrooms that work with oil-hardening tool steels on a regular basis.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDecarb-free condition — surface carbon content is intact, reducing prep time before machining or heat treating\u003c\/li\u003e\n\u003cli\u003eO-1 oil-hardening grade — stable dimensional change during hardening compared to water-hardening grades\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0.025 to plus 0.070 inches — oversize stock allows finish grinding to final dimension\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 to minus 0.000 inches — stock is never short of nominal\u003c\/li\u003e\n\u003cli\u003eWeight per foot of 33.90 pounds — consistent with standard O-1 round bar density\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard stock blank for toolroom and die shop applications requiring O-1 oil-hardening tool steel in round bar form at 3.5-inch diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of O-1 tool steel should be performed by qualified machinists or toolmakers familiar with oil-hardening grades. Always follow established shop safety procedures when operating lathes, mills, or grinders. Heat treatment, including austenitizing and oil quenching, should be conducted according to the material supplier's published thermal processing guidelines. Handle heavy-diameter bar stock with appropriate lifting aids to avoid injury.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: O-1 Oil-Hardening Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.025 to plus 0.070 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 Per Foot\u003c\/strong\u003e: 33.90 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 3.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 20102105\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: OR03.5X1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723414110514,"sku":"OR03.5X1","price":48.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc734ade68c431e7ffdf2908c56869a4_cc0fc25a-497b-4eed-b9b2-980d96540c12.jpg?v=1788604636","url":"https:\/\/voomisupply.com\/products\/value-collection-or03-5x1-o-1-tool-steel-round-3-5in","provider":"Voomi Supply","version":"1.0","type":"link"}
