Manufactured from high-speed steel (HSS) with a bright\/uncoated finish, this tap produces clean, accurate threads in a range of ferrous and non-ferrous materials. The 4-flute straight flute geometry provides chip control in through-hole and blind-hole operations, while the bottoming chamfer allows threading as close to the bottom of a blind hole as the application requires. With a 3B class of fit and H3 thread limit, the tap delivers threads suited for standard-tolerance fastener assemblies.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use in machining, maintenance, and toolroom environments where 1\/2-12 UNS threads are required. The UNS (Unified National Special) thread form is used in specialized mechanical assemblies and equipment where standard coarse or fine pitch designations do not apply. The bottoming chamfer configuration makes this tap appropriate for blind holes where full thread depth near the bottom of the bore is necessary. It is typically installed by machinists, tool-and-die professionals, and maintenance mechanics using a tap wrench, tapping head, or CNC machine tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-12 UNS thread size with bottoming chamfer for maximum thread depth in blind holes\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for chip management in a variety of materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across general-purpose tapping operations\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n  \u003cli\u003e3B class of fit with H3 thread limit for consistent standard-tolerance threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; overall length of 3.375 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or toolroom-stock tap for applications requiring 1\/2-12 UNS right-hand internal threads in blind-hole configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a tap wrench, tapping head, or appropriate machine tool spindle before use. Always apply a suitable cutting fluid matched to the workpiece material to extend tool life and improve thread finish. Secure the workpiece firmly and align the tap perpendicular to the bore before beginning the threading operation. Inspect the tap for wear or damage before each use; a worn or chipped tap can produce out-of-tolerance threads or break in the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-12\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: 4\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches\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\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: JY4844007\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694522499378,"sku":"JY4844007","price":59.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b46196056fa783409c1b848f2f7d24ef.jpg?v=1788325002","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4844007-straight-flute-tap-1-2-12-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
