Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable performance in general-purpose threading applications. The plug chamfer style features a 3 to 5 thread lead-in, making it suitable for through-holes and deep blind holes where moderate starting guidance is needed. With 4 flutes and an H4 thread limit, the JY4848065 maintains dimensional accuracy for a 3B class of fit. The overall length of 4-11\/16 inches accommodates standard tap holders and machine spindles. Installed by machinists and tool-and-die professionals in both manual and CNC tapping operations.\u003c\/p\u003e\u003cp\u003eThis tap is intended for right-hand threading operations on components requiring 7\/8-12 UNS thread forms. It is well suited for maintenance, repair, and production environments where UNS unified national special thread profiles are specified. The straight flute geometry is best matched to ferrous metals and materials that produce short, chippy cuttings. Applications include fabrication shops, industrial maintenance settings, and job shops handling custom or specialty thread specifications outside the standard UNC and UNF series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-12 UNS thread form for specialty unified national special thread applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across ferrous and general-purpose materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides 3 to 5 thread lead-in, suitable for through-holes and blind holes\u003c\/li\u003e\n\u003cli\u003e4-flute design with straight flute geometry for short-chip materials\u003c\/li\u003e\n\u003cli\u003eH4 thread limit ensures consistent 3B class of fit tolerances\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish; no coolant-through feature, compatible with standard flood or brush lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard tap holders, collet chucks, and machine spindles accepting straight-shank taps sized for 7\/8-12 UNS threading applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed by qualified machinists or toolroom personnel familiar with threading operations and proper tap alignment. Ensure the workpiece is securely fixtured and the correct drill size for 7\/8-12 UNS is used before tapping. Apply appropriate cutting fluid for the material being threaded to extend tool life and improve thread quality. Avoid excessive feed pressure or reversing without chip-clearing cycles to prevent tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-12\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\u003c\/strong\u003e: Plug\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\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\u003eOverall Length\u003c\/strong\u003e: 4-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: JY4848065\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693415661874,"sku":"JY4848065","price":130.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95dea09bdeeac54749b85d19bab9179d.jpg?v=1788312054","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4848065-straight-flute-tap-7-8-12-uns","provider":"Voomi Supply","version":"1.0","type":"link"}
