Built from high-speed steel (HSS) with a bright\/uncoated finish, this tap features a bottoming chamfer that allows threading close to the bottom of a blind hole. It carries a 3B class of fit and an H3 thread limit, making it appropriate for standard-tolerance internal thread production. The 4-flute design provides balanced cutting action and adequate chip clearance for most ferrous and non-ferrous materials. Overall length is 3-3\/8 inches with a thread length of 1-21\/32 inches.\u003c\/p\u003e\u003cp\u003eThis tap is suited for machine shops, maintenance facilities, and field service environments where 1\/2-27 UNS threads are required. The UNS (Unified National Special) thread form is used in applications where standard UN thread pitches do not meet design requirements, making this tap a specialty tool for specific mechanical assemblies and repair work. Right-hand thread direction is standard for the majority of fastening applications. The bottoming chamfer is particularly useful when full thread engagement close to the hole bottom is necessary.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for threading to near the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003e4 flutes for balanced cutting and chip evacuation\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability in general machining\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003e3B class of fit with H3 thread limit for standard internal thread tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 1\/2-27 UNS right-hand internal threads; intended for use in standard tap holders and machine tapping setups compatible with this shank size and thread form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed and operated by a qualified machinist or toolroom technician using appropriate tap holders, drill presses, mills, or CNC equipment. Ensure the pilot hole is drilled to the correct tap drill size for a 1\/2-27 UNS thread before tapping. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Never force a tap; back off periodically to break chips and prevent tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-27\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\u003eThread Length\u003c\/strong\u003e: 1-21\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: JY66556168\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717438734642,"sku":"JY66556168","price":63.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21f92ffff503bfe4b5f85da916806621.jpg?v=1788540505","url":"https:\/\/voomisupply.com\/products\/value-collection-jy66556168-straight-flute-tap-1-2-27-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
