It measures 5\/16 inches thick, 6 inches wide, and 18 inches long, and is held to a thickness tolerance of plus or minus 0.001 inches. The material conforms to AISI Type O1 specification, a standard oil-hardening tool steel known for its dimensional stability, machinability in the annealed state, and ability to hold a hardened edge after heat treatment. Machinists, toolmakers, and die makers use this flat stock as a starting blank for punches, dies, gauges, and fixture components.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for machine shop and tool room applications requiring tight dimensional control before and after heat treatment. The pre-finished surface and close tolerances reduce setup time when milling, grinding, or EDM-machining to final dimensions. It is appropriate for both small-batch prototype tooling and production die applications in manufacturing environments. The 18-inch length provides enough material for multiple blanks in typical toolroom scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for predictable hardening response in shop oil-quench operations\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision blank stock\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches for consistent fit in slot and pocket setups\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches, negative 0 inches, ensuring full usable length\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eSingle-piece package quantity suits low-volume toolroom and prototype needs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 tool steel flat stock blank for toolroom, die shop, and precision machining applications requiring AISI Type O1 oil-hardening material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eO1 tool steel flat stock is machined by qualified toolmakers and machinists using conventional milling, surface grinding, or EDM equipment. Before heat treatment, verify all features are machined to pre-grind allowances per the applicable process specification. Oil quenching should follow the material supplier heat treatment guidelines for AISI O1; improper quench rate can cause distortion or cracking. Handle hardened parts carefully to avoid edge chipping prior to finish grinding.\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: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6 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: 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 inches, minus 0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.56 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: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 54114\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541461270834,"sku":"54114","price":306.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_ecca9e45-7d74-4479-8994-bff9e73ca877.jpg?v=1785876797","url":"https:\/\/voomisupply.com\/products\/starrett-54114-o1-tool-steel-flat-stock-5-16x6x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
