Built from High-Speed Steel-E (HSS-E) with an oxide coating, it threads 3\/8-24 UNF right-hand threads and is classified at the H7 thread limit for consistent tolerance. The plug chamfer provides a gradual lead-in suited for through-hole applications. At 2.9375 inches overall length with a 0.75-inch thread length, this tap fits standard tapping chucks and holders used in machine shop and field repair work. It belongs to Kennametal Series T820 and carries material grade KSP39. Licensed machinists, tool and die makers, and maintenance mechanics are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading operations in steel, stainless steel, and cast iron. With 3 flutes and a spiral point geometry, it pushes chips forward ahead of the cut rather than packing them in the flute, making it well suited for production tapping on CNC machining centers, drill presses, and tapping machines. The 3\/8-24 UNF thread form is common in precision mechanical assemblies, hydraulic fittings, and structural fastener applications across industrial and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF right-hand thread form at H7 tolerance for precise fit\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, reducing clogging in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eHSS-E construction improves toughness and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eOxide coating reduces friction and provides light corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (approximately 3-5 thread lead-in) for smooth entry in through-hole threading\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement; compatible with flood, mist, or paste cutting lubricant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in steel, stainless steel, and cast iron.

Always ensure the workpiece is securely fixtured and the tap is properly aligned to the pilot hole before engaging the spindle. Use an appropriate cutting fluid for the workpiece material to extend tool life and reduce heat buildup. Inspect the tap for chipping or wear before each use and replace if thread form shows degradation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: H7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Spiral Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: KSP39\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.52 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.0417 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eInterrupted Thread\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\u003eMeasurement Type\u003c\/strong\u003e: Fractional Inch\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: 5416908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736781947186,"sku":"5416908","price":65.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/861d04fdd0d65732ca5807df8952d8d4_ba3fba08-da08-43e1-879e-99ad17c44a81.jpg?v=1788780313","url":"https:\/\/voomisupply.com\/products\/kennametal-5416908-spiral-point-tap-3-8-24-unf-hss-e","provider":"Voomi Supply","version":"1.0","type":"link"}
