Plug taps feature a chamfer on the first 3 to 5 threads, making them the standard starting point for threading through holes or continuing threads in a blind hole after a taper tap has been used. This tap is designed for hand tapping operations and is suited for machinists, pipefitters, and maintenance technicians who need to cut or restore internal threads in ferrous and non-ferrous materials. The HSS construction provides adequate hardness and wear resistance for general-purpose threading tasks across a wide range of shop and field applications.\u003c\/p\u003e\u003cp\u003eThis tap is appropriate for threading operations in industrial maintenance, fabrication shops, and mechanical contracting environments. The 1-1\/4 inch by 8 TPI thread form corresponds to the UNC (Unified National Coarse) standard, a commonly used thread specification in structural and heavy-duty fastening applications. It is suitable for use in mild steel, cast iron, aluminum, brass, and similar materials. Hand-tapping with this size typically requires a large tap wrench capable of handling the torque demands of a 1-1\/4 inch tap.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4 inch diameter, 8 TPI UNC thread form for heavy-duty hand tapping\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across general-purpose materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (3-5 thread lead) suits both through-hole and blind-hole threading\u003c\/li\u003e\n\u003cli\u003eDesigned for manual hand tapping with a tap wrench\u003c\/li\u003e\n\u003cli\u003eImport grade suitable for maintenance, repair, and lower-volume threading tasks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose hand plug tap for use wherever a 1-1\/4 inch by 8 TPI UNC internal thread is required; no specific equipment compatibility was stated by the manufacturer for this part.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHand plug taps of this size should be installed by a qualified machinist or maintenance technician familiar with tapping procedures for large-diameter threads. Always use cutting fluid appropriate for the workpiece material, and back the tap off a half turn periodically to break chips and prevent binding. Ensure the tap is started square to the workpiece to avoid cross-threading or tap breakage. Never apply excessive force; a large, properly sized tap wrench gives better control and reduces the risk of damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Hand Plug\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: 1.8 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-12500-8-P-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233307558194,"sku":"HT-12500-8-P-I","price":79.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622664.png?v=1780096943","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-12500-8-p-i-hss-hand-plug-tap-1-1-4-8-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
