Conforming to AISI Type O1 specification, this flat stock is manufactured to tight dimensional tolerances, making it suitable for toolmaking, die work, jig plates, and precision machined components. At 5.16 pounds, the bar is sized for bench-scale fabrication and shop use. Licensed machinists, tool-and-die makers, and metalworking professionals work with this material when they need a reliably flat, square-edged steel blank that machines predictably in the annealed condition before oil hardening.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock in this size is a common starting blank for hand tools, gauges, punches, dies, and fixture components in job shops and manufacturing environments. The 18-inch length suits single-piece tool blanks or can be cut down for multiple shorter components. The 2-inch width covers a broad range of tooling profiles without requiring initial stock removal on width.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 Oil-Hardening tool steel for good wear resistance after heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise fit in tooling applications\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches, minus 0.000 inches for consistent material sizing\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches to ensure full usable length\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends\u003c\/li\u003e\n\u003cli\u003eWeighs 5.16 pounds, ready for direct use or further machining\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI Type O1 oil-hardening tool steel flat stock for general toolmaking, die making, and precision machining applications where oil-hardening steel stock is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eO1 tool steel flat stock is worked by qualified machinists and tool-and-die makers using conventional milling, grinding, and drilling equipment. Material is typically supplied in the annealed condition and requires proper oil-hardening heat treatment by a qualified heat treater before use in hardened tooling applications. Follow applicable shop safety procedures when cutting, grinding, or machining tool steel. Eye protection, appropriate guarding, and proper chip management are required when machining this material.\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 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 0.25 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, End 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.16 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: 66780\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52083956416818,"sku":"66780","price":135.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_d72b7782-cdc6-4544-a902-d102c889da0b.jpg?v=1790057908","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-66780-o1-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
