Built from High-Speed Steel-E-PM (powder metallurgy HSS) with a TiN coating, this tap delivers consistent thread quality and extended tool life in demanding materials including stainless steel. The spiral point geometry pushes chips ahead of the cutting action and out through the exit side of the hole, making it well suited for through-hole work where chip evacuation is critical. With a 2B class of fit and H5\/H6 thread limit, it produces threads that meet standard commercial tolerance requirements. Licensed HVAC, plumbing, and mechanical trades will find this tap appropriate for precision thread repair and fabrication work.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading operations in ferrous and stainless steel workpieces. The plug chamfer style provides a gradual lead-in that distributes cutting load across several threads, making it a practical choice for production threading in CNC machines, drill presses, and hand-tapping applications where the hole passes completely through the material. It is suited for both shop and field use by machinists, pipefitters, and mechanical contractors working in light industrial and commercial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry drives chips forward through the hole for clean through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHigh-Speed Steel-E-PM (powder metallurgy) base material provides superior wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life, especially in stainless steel applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer distributes cutting load across multiple lead threads for smoother entry\u003c\/li\u003e\n  \u003cli\u003e2B class of fit with H5\/H6 thread limit meets standard commercial thread tolerance requirements\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 3\/8-16 UNC, 3-flute design for balanced cutting action\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading of 3\/8-16 UNC threads in stainless steel and similar ferrous materials.

Always ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the work surface before starting. Apply appropriate cutting fluid for the material being tapped, particularly when working in stainless steel, to prevent galling and premature wear. Power down or disengage the machine spindle before manually clearing chips or inspecting thread depth.\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 UNC\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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\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\/H6\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-E-PM (Powder Metallurgy HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel\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: 2.941 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.787 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\u003eNeck Length\u003c\/strong\u003e: 0.669 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 16\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: 3907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9039070095250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727788114226,"sku":"9039070095250","price":58.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9358f9050745325bae99f1b9936e3118.jpg?v=1788682389","url":"https:\/\/voomisupply.com\/products\/guhring-9039070095250-spiral-point-tap-3-8-16-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
