Built from high-speed steel with a titanium nitride (TiN) coating, this tap produces 4-48 UNF right-hand threads with a plug chamfer and a 2B class of fit. The TiN coating extends tool life by reducing friction and improving wear resistance. With 2 flutes and a spiral point geometry, the tap pushes chips forward ahead of the cutting zone, making it well suited for threading through-holes in ferrous and non-ferrous materials. Machinists and toolroom technicians rely on this configuration for precise, production-grade internal threading work.\u003c\/p\u003e\u003cp\u003eThis tap is used in machining operations where 4-48 UNF threads are required in through-holes. The plug chamfer provides a moderate lead-in, making it appropriate for general-purpose tapping in CNC machining centers, drill presses, and manual tapping fixtures. The H2 thread limit designation controls the tolerance of the finished thread, keeping it within the standard 2B fit range. Applications span light manufacturing, precision assembly, and toolroom work where small-diameter unified fine threads are common.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-48 UNF thread form with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides 3 to 5 thread lead-in for general-purpose through-hole tapping\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction delivers toughness in a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting tool life\u003c\/li\u003e\n\u003cli\u003eH2 thread limit ensures controlled tolerance within 2B class of fit\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, reducing chip packing in through-holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production tap for applications requiring 4-48 UNF internal threads in through-hole workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a compatible tap holder or chuck sized for a 0.141 inch shank diameter. Always use the appropriate cutting fluid for the workpiece material to maximize tool life and thread quality. Secure the workpiece firmly and ensure the tap is aligned perpendicular to the work surface before beginning the threading cycle. Inspect the tap for wear or damage before each use, as a worn tap can produce out-of-tolerance threads or break in the hole.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 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: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K008104AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734716711218,"sku":"K008104AS25","price":27.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61c61adeaf5dda1f3b943330b4f1af4a.jpg?v=1788765806","url":"https:\/\/voomisupply.com\/products\/hertel-k008104as25-spiral-point-tap-4-48-unf-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
