Manufactured from high-speed steel with a bright\/uncoated finish, this tap features 4 flutes and a right-hand thread direction. It carries a 3B class of fit and an H3 thread limit, making it suitable for standard tolerance threading applications. Overall length is 4.25 inches. This tool is intended for machinists, maintenance technicians, and trade professionals performing precision threading operations in metal components.\u003c\/p\u003e\n\u003cp\u003eThis bottoming tap is used in applications where a plug or taper tap has already started the thread and full thread engagement to the bottom of a blind hole is needed. Typical installations include threading housings, brackets, fittings, and mechanical assemblies in industrial, HVAC, plumbing, and general maintenance environments. The 3\/4-28 UNS thread designation is common in specialized mechanical and fluid-system components requiring fine-pitch threading.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the base of blind holes\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute design provides chip clearance and consistent thread form\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles a wide range of metals including mild steel, aluminum, and brass\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures proper tolerance control for 3B class of fit\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for general-purpose threading without specialized lubrication requirements\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction for standard threading operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to cut 3\/4-28 UNS right-hand internal threads with a 3B class of fit in ferrous and non-ferrous materials.

Always ensure the workpiece is securely fixtured before threading. Use appropriate cutting fluid for the material being tapped to extend tap life and improve thread finish. Inspect the pre-drilled hole diameter against the correct tap drill size for 3\/4-28 UNS before beginning to avoid tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-28\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\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: 4.25 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: JY4847273\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721830334770,"sku":"JY4847273","price":106.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82d64308fe8e695281b6732fe22df448.jpg?v=1788581630","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4847273-straight-flute-tap-3-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
