It features a plug chamfer style, which distributes cutting load across several leading threads and suits through-hole and blind-hole applications where a starter tap is used first. The tap is ground from high-speed steel (HSS) with a bright uncoated finish, giving it solid wear resistance across general-purpose threading operations. With 4 straight flutes and a Class 2G thread tolerance, it produces threads suited for moderate-fit Acme lead screw and power transmission assemblies. Machinists and toolroom technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is sized for 1-1\/2-inch diameter, 4 threads per inch Acme thread forms, making it appropriate for heavy-duty lead screw fabrication and repair, power jack components, and linear actuator threading in industrial and machine shop environments. The 2G class of fit is a standard tolerance used in general-purpose power transmission thread applications. The tandem design indicates this tap is suitable for use in a tandem tapping sequence. It is used in both production and maintenance machining contexts where Acme threads must be cut or repaired in-house.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-4 Acme thread form with 29-degree thread angle for power transmission thread cutting\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer distributes cutting load across multiple leading threads for efficient through-hole and blind-hole tapping\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for chip clearance during the threading operation\u003c\/li\u003e\n  \u003cli\u003eClass 2G tolerance ground for standard-fit Acme thread assemblies\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with bright uncoated finish for general-purpose ferrous and non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003eTandem-rated design for use in multi-tap tapping sequences\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style cutting tool for machining 1-1\/2-4 Acme internal threads in lead screws, power jacks, and linear motion components requiring a Class 2G thread fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed and used by machinists in manual or CNC tapping operations. Always secure the workpiece firmly and use appropriate tapping fluid for the material being threaded. Power down and de-energize any machine spindle before installing or removing taps. Do not exceed the tap's rated cutting capacity or apply excessive torque, as HSS taps can fracture under overload conditions.\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\/2-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Angle\u003c\/strong\u003e: 29 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTandem\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 5-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY4795324\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708152250674,"sku":"JY4795324","price":411.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ec5445357ea8a8c33705ef2609d66ea.jpg?v=1788444525","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4795324-acme-thread-tap-1-1-2-4-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
