Taper taps feature a gradual thread lead — typically 8 to 10 chamfered threads — that distributes cutting load progressively, making them the standard starting tap for threading new holes by hand. Weighing 6.3 pounds, this is a heavy-duty tool suited for threading large-diameter holes in ferrous and non-ferrous metals. Machinists, pipefitters, and maintenance trades rely on this size for structural and mechanical threading applications where a full-size starting tap is required.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in manual threading operations on large-diameter through-holes or blind holes where adequate clearance allows taper entry. Typical applications include structural steel fabrication, heavy equipment maintenance, and industrial repair work requiring 2-1\/8 inch - 8 TPI UNC threads. The taper chamfer makes it well-suited as the first tap in a multi-tap sequence or as a standalone tap in through-hole applications. It is intended for hand-tapping with a standard tap wrench sized for large-shank tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHSS construction provides hardness and wear resistance for threading steel, cast iron, and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer distributes cutting load gradually for easier starting in new holes\u003c\/li\u003e\n  \u003cli\u003e2-1\/8 inch nominal diameter at 8 TPI for large-diameter UNC thread applications\u003c\/li\u003e\n  \u003cli\u003eHand-tap geometry designed for use with a tap wrench in manual threading operations\u003c\/li\u003e\n  \u003cli\u003eWeighs 6.3 pounds — heavy-duty build consistent with large-diameter cutting tool stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for manual threading of 2-1\/8 inch - 8 TPI UNC threads in through-hole or blind-hole applications using a standard large-shank tap wrench.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed and operated by hand using a properly sized tap wrench — power driving is not recommended without appropriate speed control and is outside normal hand-tap use. Ensure the workpiece is securely fixtured before threading. Apply a suitable cutting fluid for the base material to reduce friction and extend tool life. Follow standard shop safety practices, including eye protection, when operating cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Diameter\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\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: 6.3 pounds\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-21250-8-T-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233970618674,"sku":"HT-21250-8-T-I","price":247.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622776.png?v=1780113555","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-21250-8-t-i-hss-hand-taper-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
