Built from high-speed steel with a bright, uncoated finish, this tap measures 5\/16-18 UNC and features two flutes with a plug chamfer that guides the tap into the workpiece and pushes chips forward ahead of the cut. The H5 thread limit and 2B class of fit make it well suited for standard commercial threading tolerances. Machinists and tool-and-die technicians rely on spiral point taps for production tapping in drills, tapping heads, and CNC machines where chip evacuation in through-holes is a priority.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in metal fabrication, maintenance and repair, and production machine shop environments. It is appropriate for threading through-holes in steel, iron, aluminum, and similar machinable materials where a 5\/16-18 UNC thread form is required. The plug chamfer, with its moderate lead, makes it a general-purpose choice for both hand tapping and machine tapping setups. It is sold individually and sized for standard 5\/16-18 toolholders and tap wrenches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form for standard inch-series fastener applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides good wear resistance across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 2 flutes pushes chips forward, ideal for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit with 2B class of fit meets common commercial threading tolerances\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, bright uncoated finish\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through feature; suitable for external flood coolant or tapping fluid applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use spiral point tap for standard 5\/16-18 UNC through-hole tapping operations in compatible tap wrenches, tapping heads, and CNC toolholders sized for this thread and shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or qualified tradesperson should verify correct tap drill size and hole depth before use. Always secure the workpiece and ensure the tap is properly aligned to avoid breakage. Apply appropriate tapping fluid or cutting oil to extend tap life and improve thread quality. Never reverse a broken tap without proper extraction tools, and follow applicable shop safety procedures when operating machine tooling.\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\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\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.68 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: K008394AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735449993522,"sku":"K008394AS","price":22.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2921c11d9e9b5e18fb3d7b235c860d2d.jpg?v=1788772509","url":"https:\/\/voomisupply.com\/products\/hertel-k008394as-spiral-point-tap-5-16-18-unc-2-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
