Measuring 0.5 inches in diameter and 6 feet in stock length, this round bar is produced to a tight tolerance of +0.005 to -0.015 inches, allowing machinists and tool-and-die professionals to work to close fits without additional stock removal to correct decarburization. The decarb-free surface condition means the outer layer retains its carbon content, reducing prep time before heat treatment or finish grinding. Weighing approximately 5.704 pounds per piece, it is suitable for bench or CNC lathe work.\u003c\/p\u003e\n\u003cp\u003eThis round bar is used in machine shops, toolrooms, and fabrication environments where O-1 tool steel is specified. O-1 is a general-purpose oil-hardening tool steel valued for its good machinability in the annealed state and its ability to hold sharp edges after hardening. Typical applications include punches, dies, reamers, taps, gauges, and small tool blanks. The 6-foot stock length accommodates multiple parts per bar, making it an efficient choice for low-to-medium volume toolroom production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDecarb-free surface condition preserves carbon content for direct heat treatment without additional grinding allowance\u003c\/li\u003e\n  \u003cli\u003eO-1 oil-hardening grade offers good machinability in the annealed state and reliable edge retention after hardening\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance of +0.005 to -0.015 inches supports close-tolerance toolroom work\u003c\/li\u003e\n  \u003cli\u003e6-foot stock length allows multiple parts to be cut from a single bar\u003c\/li\u003e\n  \u003cli\u003eRound bar profile suits lathe turning, centerless grinding, and milling operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard stock-length O-1 oil-hardening tool steel round bar for general toolroom and machining use where a 0.5-inch diameter round is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCutting and machining of tool steel round bar should be performed by qualified machinists using appropriate cutting tools rated for tool steel. Secure the workpiece properly in a vise, chuck, or fixture before cutting to prevent movement. When heat treating O-1 steel, follow the material manufacturer's recommended hardening and tempering procedures and use appropriate personal protective equipment. Do not attempt to cold-bend or straighten tool steel bar stock, as it may fracture.\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: 6 feet\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 to -0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.704 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: 35574110\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702950166834,"sku":"35574110","price":69.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/70808b8df31d41e04b1de39c28ab2e2f_227c0e95-8ede-409b-91a6-29de7f9c3fe0.jpg?v=1788414078","url":"https:\/\/voomisupply.com\/products\/value-collection-35574110-o-1-tool-steel-round-bar-0-5-in-6-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
