O-1 tool steel is a general-purpose, oil-hardening grade known for good dimensional stability during heat treatment and high wear resistance after hardening. The decarb-free condition means the outer surface retains its full carbon content, which is critical when machining close to final dimensions before hardening. This bar measures 0.5 inches in diameter with a tolerance of positive 0.005 to negative 0.015 inches, and weighs approximately 3.1 pounds. It is suited for machinists, tool-and-die makers, and metalworking shops requiring a reliable, ready-to-machine tool steel blank.\u003c\/p\u003e\n\u003cp\u003eThis round bar is a stock-length material used in the fabrication of punches, dies, gauges, reamers, taps, and general tooling components. The 3-foot stock length allows a machinist to cut multiple blanks from a single piece, reducing material waste. O-1 tool steel machines well in the annealed condition and responds predictably to oil quench hardening, making it a standard choice in job shops and maintenance toolrooms handling moderate-production tooling needs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDecarb-free surface retains full carbon content for reliable heat treatment response\u003c\/li\u003e\n  \u003cli\u003eO-1 oil-hardening grade offers good wear resistance and dimensional stability during hardening\u003c\/li\u003e\n  \u003cli\u003e0.5 inch diameter with tight tolerance of positive 0.005 to negative 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e3-foot stock length suitable for cutting multiple tool blanks\u003c\/li\u003e\n  \u003cli\u003eAnnealed condition allows straightforward machining before heat treatment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose stock material for tool-and-die, punch, gauge, and tooling fabrication applications requiring O-1 oil-hardening tool steel in round bar form.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCutting and machining should be performed with tooling appropriate for hardened or annealed tool steel stock. Heat treatment, including hardening and tempering, should be carried out by qualified personnel following established metallurgical procedures for O-1 grade steel. Always use appropriate personal protective equipment when cutting, grinding, or heat treating steel bar stock. Consult applicable shop safety standards before beginning any thermal processing operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: O-1 Oil-Hardening\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3 feet (36 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.005 \/ -0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 20102105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 35574003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692279988530,"sku":"35574003","price":38.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/70808b8df31d41e04b1de39c28ab2e2f_e005905d-ed14-4e4a-80f3-c4ea72580999.jpg?v=1788295630","url":"https:\/\/voomisupply.com\/products\/value-collection-35574003-o-1-tool-steel-round-bar-0-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
