Plug taps feature a tapered lead of 3 to 5 threads, making them the standard starting choice for through-holes and for chasing threads in most production and repair applications. This import-grade tap is suited for manual tapping operations in machine shops, pipe and mechanical fitting work, and heavy maintenance tasks where a large-diameter coarse thread is required. The HSS construction provides adequate hardness and wear resistance for threading mild steel, cast iron, aluminum, and similar materials by hand.\u003c\/p\u003e\u003cp\u003eThis tap is appropriate for applications requiring a 2-1\/4 inch - 8 TPI Unified National Coarse (UNC) or compatible thread form in heavy industrial, structural, or mechanical assembly work. Typical use cases include large fastener repair, custom fabrication, and maintenance of heavy equipment where large-diameter threaded connections are serviced or created. It is intended for hand tapping with a standard tap wrench and is not designed for machine or CNC tapping cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-1\/4 inch diameter with 8 TPI coarse thread pitch for large-diameter threading work\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides hardness suitable for threading ferrous and non-ferrous materials by hand\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (3 to 5 thread lead) allows use in through-holes and most blind-hole applications with pre-existing thread starts\u003c\/li\u003e\n\u003cli\u003eImport-grade tap offers a cost-effective option for low-frequency large-diameter threading tasks\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1, suitable for single-unit procurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in manual tapping applications requiring a 2-1\/4 inch - 8 TPI thread form.

Secure the workpiece firmly before tapping and ensure the pilot hole diameter is correctly sized for a 2-1\/4 inch - 8 TPI thread per standard tap drill charts. Apply cutting fluid throughout the tapping process and back off the tap periodically to break chips and prevent binding. Do not force the tap if resistance increases sharply, as tap breakage in large-diameter HSS taps can result in significant workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-1\/4 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 Plug Tap\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\u003cli\u003e\n\u003cstrong\u003eMinimum Order 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: EAGLE CUTTING TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HT-22500-8-P-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233991885106,"sku":"HT-22500-8-P-I","price":255.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622774.png?v=1780114268","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-22500-8-p-i-hss-hand-plug-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
