Taper taps feature a gradual lead that distributes cutting load across several threads, making them well suited for starting threads in through-holes or moderately tough materials. This tap is an import-grade tool commonly used by machinists, pipefitters, and maintenance trades when threading large-diameter holes in metal or similar materials where a full HSS taper profile is required.\u003c\/p\u003e\n\u003cp\u003eThis tap is applicable to large-diameter threading operations found in industrial maintenance, heavy fabrication, and mechanical repair scenarios. Its 4-inch by 8 TPI specification places it in the range of coarse unified national (UNC) thread standards commonly encountered in structural and heavy-duty mechanical assemblies. It is suited for use in machine shops, field maintenance environments, and fabrication settings where manual or machine tapping of oversized holes is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction provides good wear resistance and hardness for threading metal workpieces\u003c\/li\u003e\n  \u003cli\u003eTaper lead design distributes cutting forces gradually, reducing the risk of tap breakage when starting a thread\u003c\/li\u003e\n  \u003cli\u003e4-inch diameter at 8 TPI addresses large-diameter threading requirements in heavy fabrication and industrial maintenance\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 allows single-unit purchase for individual job or replacement needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard taper tap for cutting 4-inch by 8 TPI internal threads consistent with coarse unified national thread form specifications.

Ensure the workpiece is securely fixtured and the tap is properly aligned with the pre-drilled hole before beginning the threading operation. Apply appropriate cutting fluid throughout the operation to reduce heat buildup and extend tool life. De-energize and lock out any powered equipment before performing threading operations on installed machinery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: 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: 8.4 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-40000-8-T-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233495187762,"sku":"HT-40000-8-T-I","price":718.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622923.png?v=1780101371","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-40000-8-t-i-hss-taper-tap-4in-8tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
