Built from high speed steel (HSS) with a bright uncoated finish, this tap delivers reliable performance in manual tapping operations. The plug chamfer style features a moderate lead-in of approximately 3 to 5 threads, making it the standard choice for through-hole tapping where a starter tap is not required. At 4 inches overall length, the JY4870119 provides adequate reach and leverage for hand-tapping with a T-handle or tap wrench. Machinists, tool-and-die makers, and maintenance technicians in industrial and MRO environments are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for producing Class 3B internal threads conforming to the Unified National Special (UNS) thread standard at 1-1\/4-14. The 14 threads-per-inch pitch targets applications where a coarser thread is needed on larger-diameter fasteners, including hydraulic fittings, mechanical assemblies, and heavy equipment components. The 4-flute straight-flute geometry suits most through-hole and blind-hole applications in softer to medium-hardness materials. Thread limit H4 indicates the tap is ground to produce threads at the upper tolerance range, providing adequate clearance for plated or coated fastener engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-14 UNS thread form, Class 3B fit for tight-tolerance internal threading\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides 3 to 5 thread lead-in, suitable for through-hole and most blind-hole work\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction resists heat and wear during hand tapping\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003e4-flute straight-flute design promotes chip clearance in a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit accommodates plated or coated mating fasteners\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction matches standard fastener engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use hand tap for applications requiring 1-1\/4-14 UNS Class 3B internal threads.

Secure the workpiece firmly before beginning; use a tap guide or drill press alignment fixture to keep the tap perpendicular to the work surface. Apply cutting fluid appropriate for the workpiece material throughout the tapping operation to reduce heat and extend tool life. Reverse the tap periodically to break chips and prevent tap binding or breakage in deep holes.\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\/4-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY4870119\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693690257714,"sku":"JY4870119","price":145.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6105250a2bee7dccfc1f818735e7e65.jpg?v=1788316128","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4870119-hand-tap-1-1-4-14-uns-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
