Ground to tight dimensional tolerances, it is supplied in AISI Type O1 oil-hardening steel, a widely used cold-work tool steel valued for its machinability, edge retention after hardening, and dimensional stability through the oil-quench hardening process. The bar measures 5\/32 inches thick, 2 inches wide, and 36 inches long, with a thickness tolerance of plus or minus 0.001 inches. It weighs 3.19 pounds per bar. Machinists, toolmakers, and die makers install this stock in job shops, tool rooms, and manufacturing facilities.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabricating cutting tools, dies, punches, jigs, fixtures, and gauging components where precise pre-hardened stock dimensions reduce setup time. The annealed condition allows conventional milling, drilling, and grinding before heat treatment. After oil-hardening, the material achieves the hardness and wear resistance required for production tooling applications. It is appropriate for both prototype and short-run production work where tight tolerance stock is required off the shelf.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for reliable heat-treat response\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for precise fit-up\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness: all edges within 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003eSupplied annealed, ready for machining prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-format O1 tool steel flat bar for use in tool room and die shop applications requiring AISI Type O1 oil-hardening material in 5\/32 x 2 x 36-inch flat stock form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, milling, and grinding should be performed by a qualified machinist using appropriate tooling for tool steel stock. Oil-hardening heat treatment must be performed by a qualified heat treater following established procedures for AISI O1 tool steel. Exercise proper machine guarding and personal protective equipment when cutting or grinding. Material should be stored flat and dry to prevent distortion or surface corrosion prior to use.\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\/32 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: 36 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 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch, all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.19 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: 54330\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539419169074,"sku":"54330","price":163.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_bdbbae5f-654f-40ee-8e7c-9de735e06f40.jpg?v=1785839817","url":"https:\/\/voomisupply.com\/products\/starrett-54330-o1-tool-steel-flat-stock-5-32x2x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
