Built from High-Speed Steel-E (HSS-E) with a multi-layer TiN, CrC, and C coating, this tap delivers extended wear resistance and improved performance in demanding materials. It features a plug chamfer for standard through-hole entry, three flutes, and a right-hand thread direction. Overall length is 3.1575 inches with a thread length of 0.88 inches. The H3 thread limit designation indicates a standard oversize tolerance appropriate for tapping most general and close-tolerance UNF threads. This tool is used by machinists, maintenance technicians, and toolroom professionals working in production and repair environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for use in stainless steel and non-ferrous metals, making it well suited for aerospace, automotive, and industrial maintenance applications where those materials are common. The spiral point design pushes chips forward through the hole, keeping the flutes clear and reducing the risk of chip packing during through-hole operations. It is part of the KENNAMETAL T820 series, which is engineered for consistent performance in high-volume and precision tapping scenarios. The 7\/16-20 UNF thread specification is widely used in hydraulic fittings, fastener assemblies, and precision mechanical components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16-20 UNF thread form with H3 thread limit for close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eHSS-E base material provides toughness and heat resistance beyond standard HSS\u003c\/li\u003e\n  \u003cli\u003eMulti-layer TiN, CrC, and C coating extends tool life in stainless steel and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, optimized for through-hole threading\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer allows standard starting depth suitable for most through-hole setups\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 3-flute design balances chip clearance and thread form stability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for through-hole threading in stainless steel and non-ferrous metal workpieces.

Ensure the spindle and workpiece are properly secured and that the correct tapping fluid or cutting oil is applied before operation, particularly when working in stainless steel. Confirm machine spindle direction and torque settings are appropriate for the tap diameter and material before engaging the cut. Never reverse a spiral point tap under load without fully disengaging the cut, as this can cause tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20 UNF\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: 20\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\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\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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\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\u003eOverall Length\u003c\/strong\u003e: 3.1575 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.61 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.05 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\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: 5416912\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51746337947954,"sku":"5416912","price":82.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/861d04fdd0d65732ca5807df8952d8d4_203fdf73-6ac3-4d34-9958-55e9fc9809a8.jpg?v=1788868596","url":"https:\/\/voomisupply.com\/products\/kennametal-5416912-spiral-point-tap-7-16-20-unf-hss-e","provider":"Voomi Supply","version":"1.0","type":"link"}
