It carries an 8-32 UNC thread form with a plug chamfer, 3 flutes, and a right-hand thread direction. The tap is manufactured from High-Speed Steel-E-PM (powder metallurgy HSS) and finished with a TiN (titanium nitride) coating for improved wear resistance and tool life. With a 2B class of fit and an H3\/H4 thread limit, it produces threads that meet standard tolerance requirements for general mechanical assemblies. Licensed machinists, maintenance technicians, and toolroom professionals are the primary users of this tap.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole threading operations in production and maintenance environments. Its spiral point geometry pushes chips forward through the hole, making it particularly effective in through-hole applications on stainless steel, mild steel, and similar materials. The 8-32 UNC size is a common fastener thread found in instrumentation panels, enclosures, and light structural assemblies. The TiN coating provides additional resistance to built-up edge, which is especially valuable when threading work-hardening alloys such as austenitic stainless steel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, optimized for through-hole threading\u003c\/li\u003e\n\u003cli\u003eHigh-Speed Steel-E-PM (powder metallurgy) construction provides consistent hardness and toughness\u003c\/li\u003e\n\u003cli\u003eTiN coating improves wear resistance and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003e8-32 UNC thread form with plug chamfer for general-purpose starting ease\u003c\/li\u003e\n\u003cli\u003e2B class of fit with H3\/H4 thread limit for standard tolerance threaded assemblies\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, 3 flutes, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole threading in stainless steel and comparable materials. Produces 8-32 UNC internal threads per the Series 3907 specifications with a 2B class of fit. Verify workpiece material hardness and pre-drill hole size against standard UNC tap drill charts before use.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed in a manual tap handle, tapping head, or CNC rigid-tapping spindle by a machinist or maintenance technician. Ensure the pre-drilled hole diameter matches the recommended tap drill size for 8-32 UNC before beginning. Apply appropriate cutting fluid for the workpiece material, particularly when threading stainless steel, to reduce heat and prevent galling. Do not exceed the tap's rated thread limit or force the tap against an interrupted thread without confirming compatibility with the interrupted thread geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\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: H3\/H4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Spiral Point\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 (HSS-E-PM)\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: 2.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.512 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 0.0313 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: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9039070041660\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732727660850,"sku":"9039070041660","price":38.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9358f9050745325bae99f1b9936e3118_71b99468-625f-41a8-9fac-9b0e46016912.jpg?v=1788746079","url":"https:\/\/voomisupply.com\/products\/guhring-9039070041660-spiral-point-tap-8-32-unc-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
