Built from powdered metal for improved wear resistance and edge retention, it features a titanium nitride (TiN) coating that reduces friction and extends tool life in production environments. The plug chamfer eases entry into the workpiece, while the 3-flute spiral point geometry pushes chips forward ahead of the tap, keeping the thread clear during cutting. With an H3 thread limit and Class 3B fit, it produces tight-tolerance threads suited to precision assemblies. Overall length is 2.941 inches with a shank diameter of 0.381 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for cutting 3\/8-24 UNF right-hand internal threads in through-hole configurations. It is well suited for use in ferrous and stainless steel workpieces where chip evacuation and thread quality are critical. The Series 3997 designation identifies this as part of a professional-grade tapping line used by machinists and tool-room technicians in both production and job-shop settings. The plug style makes it a standard choice for machine tapping operations where a starting chamfer is appropriate.\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 tapping\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction provides superior hardness and wear resistance over HSS\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life, especially in stainless steel\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit with Class 3B fit for precise, consistent thread tolerances\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for standard machine tapping entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 3 flutes, 24 threads per inch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading of 3\/8-24 UNF right-hand threads, with a material application rating for stainless steel.

Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the hole before beginning the threading cycle. Use cutting fluid rated for stainless steel to reduce heat buildup and prevent galling. Do not reverse the tap while chips are compacted, as this may damage the flutes or the thread form.\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\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: 24\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\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\u003eClass of Fit\u003c\/strong\u003e: 3B\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.941 inches (75.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 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: 3997\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.025 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: 9039970095250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51736739021106,"sku":"9039970095250","price":55.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13818b0ff8f782969e9f0c743191e66e_35d0aae1-4006-4d63-be13-3a7f13973946.jpg?v=1788779670","url":"https:\/\/voomisupply.com\/products\/guhring-9039970095250-spiral-point-tap-3-8-24-unf-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
