A taper tap features a gradual thread lead that helps start a new thread in an unthreaded hole, distributing cutting load across multiple teeth for easier initial engagement. This tool is used by machinists, pipefitters, and maintenance trades to cut internal threads by hand using a tap wrench or suitable driver. The HSS construction provides adequate hardness and wear resistance for threading steel, cast iron, aluminum, and similar materials in general-purpose shop and field applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading 1-1\/4 inch holes with a 7 TPI Unified National Coarse (UNC) thread form, a common fastener thread used in heavy-duty mechanical and structural assemblies. Typical applications include threading pipe flanges, heavy equipment components, and large-diameter fastener holes in fabrication and repair work. It is appropriate for use in both shop environments and field maintenance situations where hand tapping of large-diameter threads is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4 inch diameter, 7 TPI UNC thread profile for large-diameter hand tapping\u003c\/li\u003e\n  \u003cli\u003eTaper lead geometry distributes cutting load for easier thread starting in new or blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction provides hardness suitable for general-purpose threading applications\u003c\/li\u003e\n  \u003cli\u003eHand tap design intended for use with a tap wrench for controlled manual thread cutting\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose hand taper tap for cutting 1-1\/4 inch - 7 TPI UNC internal threads in unthreaded through holes or blind holes across a range of ferrous and non-ferrous base materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHand tapping should be performed by a qualified machinist or tradesperson using a properly sized tap wrench to maintain axial alignment with the drilled hole. Ensure the workpiece is securely clamped before tapping, and use an appropriate cutting fluid to reduce heat and extend tap life. Advance the tap in short increments, reversing periodically to break chips and prevent tap binding or breakage. Follow applicable shop safety practices and relevant trade standards when performing threading operations on pressurized or structural components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4 inch - 7 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Style\u003c\/strong\u003e: Hand Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HT-12500-7-T-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233548042546,"sku":"HT-12500-7-T-I","price":88.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622666.png?v=1780102843","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-12500-7-t-i-hand-taper-tap-1-1-4in-7-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
