Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable thread-cutting performance in ferrous and non-ferrous materials. The bottoming chamfer allows threads to be cut to the bottom of a blind hole, and the 3B class of fit ensures compatibility with standard tolerance assemblies. With six flutes and an H4 thread limit, it is suited for controlled, accurate thread production in machine shop and maintenance environments. Overall length is 4 inches. Installed by machinists, toolroom technicians, and maintenance mechanics.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in applications requiring a 1-1\/4-16 UNS right-hand thread in a blind-hole configuration where full thread depth to the bottom of the bore is required. The bottoming chamfer design makes it the final tap used in a three-tap sequence, following a taper and plug tap in harder materials, or used alone in pre-tapped or through-drilled setups. Typical applications include heavy equipment repair, tooling fixtures, and industrial machinery maintenance where UNS thread forms are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eSix flutes provide chip clearance and consistent thread form\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit for controlled fit tolerance\u003c\/li\u003e\n  \u003cli\u003e3B class of fit meets standard internal thread tolerance requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 1-1\/4-16 UNS right-hand internal threads in blind-hole applications requiring a bottoming tap with a 3B class of fit and H4 thread limit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstalled by machinists and maintenance technicians using a tap wrench, tapping head, or CNC rigid tapping setup. Always ensure the workpiece is properly secured and the correct tap drill size for a 1-1\/4-16 UNS thread is used before tapping. Apply an appropriate cutting fluid to reduce heat and extend tool life. For blind holes, clear chips periodically by reversing the tap to prevent chip packing and tap breakage.\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\/4-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: JY4870150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716552818994,"sku":"JY4870150","price":179.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1120dcfc5befe301627627ce3d4ee6ad.jpg?v=1788527733","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4870150-straight-flute-tap-1-1-4-16-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
