Ground and held to tight tolerances, it measures 7\/32 inch thick, 2 inches wide, and 36 inches long, with a thickness tolerance of +\/- 0.001 inches and a length tolerance of +0.015 inches. Manufactured to AISI Type O1 specification, this flat stock is suited for machinists, tool and die makers, and fabricators who require consistent stock material that responds predictably to oil-hardening heat treatment.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock sees regular use in machine shops and fabrication environments for making punches, dies, gauges, bushings, and general-purpose tooling. The 36-inch bar length provides material for multiple tool blanks from a single piece. The 2-inch width accommodates a broad range of flat tool profiles without requiring additional mill passes. This bar ships in single-piece quantities, making it practical for job shops and maintenance toolrooms that need specific lengths without committing to full bundle orders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel — hardens in oil quench for controlled, predictable heat treat response\u003c\/li\u003e\n\u003cli\u003eThickness tolerance held to +\/- 0.001 inches for precision fit-up without additional grinding on critical dimensions\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to -0.005 inches ensures stock falls at or under nominal for tight clearance applications\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch across all edges\u003c\/li\u003e\n\u003cli\u003e36-inch bar length yields multiple tool blanks from a single piece of stock\u003c\/li\u003e\n\u003cli\u003eWeighs 4.46 pounds — manageable for bench handling and vise setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 oil-hardening tool steel flat stock bar suitable for toolmaking, die making, and precision fabrication applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed with appropriate metalworking equipment including band saws, milling machines, or surface grinders rated for tool steel. Heat treatment — annealing, hardening, and tempering — must follow established metallurgical procedures for AISI O1 and should be performed by qualified personnel with proper quench media and temperature control equipment. Handle cut edges carefully, as tool steel burrs present a laceration hazard. Secure the bar firmly in a vise or fixture before any cutting or grinding operation.\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: 7\/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: +\/- 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: 0.000 to -0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.003 inches per inch, all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.46 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: 54358\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541378990386,"sku":"54358","price":265.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_a3a12b46-3268-4583-a150-fddf49f05651.jpg?v=1785874143","url":"https:\/\/voomisupply.com\/products\/starrett-54358-o1-tool-steel-flat-stock-7-32x2x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
