It features a 5\/16-18 UNC thread form with a plug chamfer, making it well suited for starting threads in pre-drilled holes and cutting full threads through the material. Manufactured from high-speed steel with a titanium nitride (TiN) coating, this tap offers improved wear resistance and longer tool life compared to uncoated HSS alternatives. The two-flute spiral point design pushes chips forward ahead of the tap, keeping the flutes clear during cutting. Thread limit is H2, suitable for general-purpose tolerance requirements.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shop, production, and maintenance environments for cutting 5\/16-18 UNC internal threads in through-hole applications. It is appropriate for use in ferrous and non-ferrous metals where a right-hand thread is required. The plug chamfer style makes it a standard choice for CNC tapping, drill press tapping, and manual tapping operations where the tool can pass completely through the workpiece. Coolant-through capability is not included in this design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for general-purpose through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction for extended tool life\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral point geometry pushes chips forward to prevent clogging\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for standard tolerance fits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or production spiral point tap for through-hole tapping operations requiring 5\/16-18 UNC right-hand threads.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists and maintenance technicians using a tapping machine, CNC machining center, drill press with tapping attachment, or a hand tap wrench. Always ensure the pre-drilled hole diameter matches the recommended tap drill size for 5\/16-18 UNC before beginning. Power down and secure the workpiece before tapping operations. Use an appropriate cutting fluid for the workpiece material to reduce heat and extend tap life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\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: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3180 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: K008390AS25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734970597682,"sku":"K008390AS25","price":33.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ce218b0a86b5741e0d693749a1a82a3.jpg?v=1788768718","url":"https:\/\/voomisupply.com\/products\/hertel-k008390as25-spiral-point-tap-5-16-18-unc-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
