It is manufactured from High-Speed Steel-E-PM (powder metallurgy HSS) and finished with a TiN (titanium nitride) coating that extends tool life in abrasive materials. The tap features a plug chamfer, 4 flutes, and a right-hand thread direction, with an overall length of 5.13 inches and a thread length of 1.496 inches. It meets a 2B class of fit and a thread limit of H6\/H7, making it suitable for general-purpose and precision threading work. HVAC, plumbing, and mechanical contractors installing equipment with 1-inch threaded fasteners will find this tap compatible with standard hand tap holders and CNC tapping cycles alike.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for stainless steel applications, which makes it well suited for corrosion-resistant pipe fittings, structural brackets, and mechanical assemblies where harder alloys are common. The spiral point design pushes chips forward ahead of the cut, keeping the flutes clear during through-hole operations. It is part of the GUHRING Series 3907 and is sold individually. Licensed machinists, pipefitters, and maintenance mechanics working in light industrial and commercial service environments are the primary users of this tap.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC thread form with plug chamfer for standard through-hole entry\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral point geometry pushes chips forward to prevent clogging in through-hole cuts\u003c\/li\u003e\n  \u003cli\u003eHigh-Speed Steel-E-PM construction offers improved wear resistance over conventional HSS\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in stainless steel and hard alloys\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 2B class of fit, H6\/H7 thread limit for precision fitment\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design — compatible with standard external flood or mist cooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading applications in stainless steel workpieces.

Shut down and lock out any powered equipment before hand-tapping in the field. Use appropriate cutting fluid rated for stainless steel to reduce heat buildup and galling. Verify the drilled hole diameter meets the correct tap drill size for a 1-8 UNC thread before beginning the tapping operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 8\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: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H6\/H7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: High-Speed Steel-E-PM (Powder Metallurgy HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.496 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.125 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: 3907\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9039070254000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51749331566898,"sku":"9039070254000","price":204.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9358f9050745325bae99f1b9936e3118_15b01a10-3f15-403f-8640-1d2cbc363ec8.jpg?v=1788904618","url":"https:\/\/voomisupply.com\/products\/guhring-9039070254000-spiral-point-tap-1-8-unc-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
