Built from high-speed steel (HSS), it delivers the hardness and heat resistance needed for production tapping in ferrous and non-ferrous metals. The spiral point geometry pushes chips forward ahead of the cutting teeth, keeping flutes clear and reducing the chance of chip packing in through-hole applications. At 6 inches overall length (OAL), this tap reaches into recessed bosses, deep fixtures, or obstructed setups where a standard-length tap cannot gain access. Machinists, toolmakers, and maintenance technicians in metalworking shops are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole tapping operations in materials such as mild steel, aluminum, and similar machinable metals. Its extended OAL makes it a practical choice for production machining, CNC tapping centers, and manual drill press work where clearance is limited. The H3 thread limit provides a controlled fit tolerance appropriate for general-purpose 3B class fits, making it compatible with standard 3\/8-16 fastener assemblies used across industrial, manufacturing, and maintenance-repair-overhaul (MRO) environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, ideal for through-hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for controlled tolerance on 3B class of fit threads\u003c\/li\u003e\n  \u003cli\u003e6 inch OAL extends reach into recessed or obstructed work areas\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) for easy starting and general-purpose tapping\u003c\/li\u003e\n  \u003cli\u003e3 flute design balances chip clearance and cutting edge strength\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 3\/8-16 UNC internal threads to a 3B class of fit in through-hole applications across standard metalworking and MRO operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the workpiece is securely fixtured and properly center-drilled before tapping. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Never reverse-cycle a spiral point tap in a CNC tapping center without confirming the machine supports synchronized tapping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduced Shank\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JY9975665\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51705197035826,"sku":"JY9975665","price":58.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f14ca4eab442bf4f98c9eafb1f9cb991.jpg?v=1788427420","url":"https:\/\/voomisupply.com\/products\/value-collection-jy9975665-extension-tap-3-8-16-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
