It cuts a 9\/16-18 UNF right-hand thread and features a plug chamfer entry with 3 flutes that push chips ahead of the tap during cutting. The tap is manufactured from High-Speed Steel-E (HSS-E), a cobalt-alloyed grade that resists heat and wear in tough materials. A triple coating of TiN, CrC, and C further improves lubricity and tool life. The H3 thread limit provides a standard tolerance class suitable for most UNF threaded fastener fits. This tap belongs to KENNAMETAL Series T820 and carries material grade KSMN34.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole applications in production and maintenance environments where stainless steel and non-ferrous workpieces require a fine 18 TPI thread. The spiral point geometry is most effective in through-holes where chips can exit freely ahead of the cutting edges. Typical users include machinists, tool-and-die tradespeople, and maintenance technicians working on CNC machines, manual mills, or drill presses. It is sold individually with a minimum order quantity of one piece.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16-18 UNF thread form with right-hand cut and H3 thread limit tolerance\u003c\/li\u003e\n  \u003cli\u003eHSS-E cobalt-alloyed construction for improved heat and wear resistance in stainless steel\u003c\/li\u003e\n  \u003cli\u003eTriple coating — TiN, CrC, and C — reduces friction and extends tool life\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, ideal for through-hole threading\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) for general-purpose starting in pre-drilled holes\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement; suitable for standard tapping with cutting fluid applied externally\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading of stainless steel and non-ferrous metals requiring a 9\/16-18 UNF right-hand thread.

Always secure the workpiece and ensure the tap is properly aligned with the pre-drilled hole before engagement to avoid tap breakage. Apply a suitable cutting fluid or tapping compound rated for stainless steel or the target non-ferrous material. Follow shop safety practices and any applicable machine guarding requirements when operating powered tapping equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 18\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\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Spiral Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: HSS-E (High-Speed Steel-E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KSMN34\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN, CrC, C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5905 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.7400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4290 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.0556 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T820\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5416940\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727267397938,"sku":"5416940","price":140.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/861d04fdd0d65732ca5807df8952d8d4_ae89063c-d798-43f4-8b7e-05282a788450.jpg?v=1788675670","url":"https:\/\/voomisupply.com\/products\/kennametal-5416940-spiral-point-tap-9-16-18-unf-hss-e","provider":"Voomi Supply","version":"1.0","type":"link"}
