Built from high-speed steel with a titanium nitride (TiN) coating, it produces 7\/16-14 UNC right-hand threads across a thread length of 1-7\/16 inches. The plug chamfer distributes cutting load across several leading threads, making it suitable for general-purpose tapping in a wide range of materials. With 4 flutes and an overall length of 3-5\/32 inches, this tap is sized for standard machine and hand tapping operations. The H3 thread limit indicates a tolerance class appropriate for standard fit applications. Machinists, maintenance technicians, and tool-room operators rely on this type of tap for production and repair threading work.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading ferrous and non-ferrous materials in job-shop, production, and maintenance environments. The TiN coating reduces friction and extends tool life compared to uncoated high-speed steel, making it a practical choice for moderate-volume threading operations. The straight flute design works best in through-holes or short blind holes where chip evacuation is not a critical concern. Coolant-through capability is not provided, so conventional flood or mist coolant applied externally is recommended when operating at higher speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16-14 UNC thread form for standard fractional inch thread applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides toughness for general-purpose tapping\u003c\/li\u003e\n\u003cli\u003eTitanium nitride (TiN) coating reduces friction and increases surface hardness for longer tool life\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 4 flutes distributes cutting forces for smooth thread entry\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for standard tolerance fits\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for conventional tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tap for any application requiring a 7\/16-14 UNC straight flute plug tap in high-speed steel with TiN coating.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists and maintenance technicians using a tap wrench, tapping head, or CNC machine spindle. Ensure the workpiece is securely fixtured and the pilot hole diameter matches the recommended tap drill size for 7\/16-14 UNC threads before beginning. Apply appropriate cutting fluid to the tap and workpiece to prevent galling and extend tool life. Do not force the tap if resistance increases unexpectedly — back off to clear chips before continuing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14 UNC\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: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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: Titanium Nitride (TiN)\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: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-5\/32 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: 0.06 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: K008477AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729909874994,"sku":"K008477AS25","price":43.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91f36c4bf82e8ed1c6132550b83f70ea.jpg?v=1788709815","url":"https:\/\/voomisupply.com\/products\/hertel-k008477as25-straight-flute-tap-7-16-14-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
