Manufactured to AISI Type O1 material specification, this flat stock measures 3\/32 inches thick, 1-1\/2 inches wide, and 18 inches long. Thickness tolerance is held to +\/- 0.001 inches, making it well-suited for applications where close dimensional accuracy is required before heat treatment. Machinists and tool-and-die makers rely on O1 stock for its predictable oil-quench hardening characteristics and good wear resistance in the hardened state.\u003c\/p\u003e\u003cp\u003eThis flat stock is appropriate for fabricating cutting tools, punches, dies, gauges, and similar toolroom components in both job shop and production environments. The 18-inch length and 1-1\/2-inch width provide workable material for a range of bench or machine operations. At 0.72 pounds per piece, it is easy to handle at the bench or on a surface grinder. One piece is supplied per package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for predictable heat treatment response\u003c\/li\u003e\n\u003cli\u003eThickness: 3\/32 inches, held to +\/- 0.001 inches tolerance\u003c\/li\u003e\n\u003cli\u003eWidth: 1-1\/2 inches with tolerance of 0.0000 to -0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with tolerance of +0.250 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness: all edges held to 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging with no minimum order above one unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-tolerance O1 tool steel flat stock suitable for general toolroom, die-making, and precision machining applications requiring oil-hardening material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed by a qualified machinist using appropriate cutting fluids and tooling rated for high-carbon steel. Hardening requires controlled furnace heat treatment followed by an oil quench — this process should only be performed by personnel trained in metallurgical heat treatment procedures. Always wear appropriate PPE when cutting, grinding, or heat-treating tool steel. Verify final dimensions after any grinding operations, as stock may shift slightly during setup.\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: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/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: +\/- 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: 0.0000 to -0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.250 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: 0.72 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 53982\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540229423410,"sku":"53982","price":80.66,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_87aace47-4bda-459f-98b0-e447892086c2.jpg?v=1785849586","url":"https:\/\/voomisupply.com\/products\/starrett-53982-o1-tool-steel-flat-stock-3-32x1-1-2x18in","provider":"Voomi Supply","version":"1.0","type":"link"}
