Built from high-speed steel with a titanium nitride (TiN) coating, it delivers improved surface hardness and wear resistance compared to uncoated tooling. The 2-flute spiral point geometry pushes chips forward ahead of the cutting action, keeping the flutes clear during production tapping. With a 1-inch thread length and H1 thread limit, it suits general-purpose machine tapping in ferrous and non-ferrous materials. Machinists, toolmakers, and maintenance technicians use this tap in CNC machining centers, drill presses, and tapping machines.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole tapping in production and job-shop environments where chip evacuation must remain consistent. The plug chamfer — typically 3 to 5 threads of lead — allows the tap to start easily while distributing cutting load across multiple teeth. It is commonly specified for tapping mild steel, aluminum, and similar workpiece materials in 1\/4-20 UNC thread specifications. The H1 thread limit provides close tolerance control, making it appropriate for applications requiring a snug thread fit. Coolant-through is not supported on this model.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread form with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral point geometry pushes chips forward for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for easy tap starting and distributed cutting load\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for general-purpose tapping in a range of materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and extends tool life over uncoated HSS\u003c\/li\u003e\n  \u003cli\u003eH1 thread limit for close-tolerance thread control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling selection for machine tapping operations requiring 1\/4-20 UNC right-hand threads in through-hole workpieces.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is intended for use by machinists and toolmakers in machine tapping applications. Before mounting, verify the spindle speed and feed rate are appropriate for the workpiece material and tap size. Ensure the tap holder provides proper alignment to prevent tap breakage. Use appropriate cutting fluid or tapping compound for the workpiece material to maximize tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches\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\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: K008330AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738224722226,"sku":"K008330AS25","price":28.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dbb8734c075bd17f7f75b715838c0bd8.jpg?v=1788796963","url":"https:\/\/voomisupply.com\/products\/hertel-k008330as25-spiral-point-tap-1-4-20-unc-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
