Manufactured from High-Speed Steel-E-PM (powder metallurgy HSS) with a Titanium Nitride (TiN) coating, this tap delivers extended tool life in demanding production environments. It cuts an 8-32 UNC thread at 32 threads per inch, features 3 flutes with a plug chamfer entry, and conforms to a 2B class of fit. The overall length is 2.48 inches with a thread length of 0.827 inches and a shank diameter of 0.168 inches. This tool is intended for use by machinists, maintenance technicians, and tool-and-die professionals requiring consistent, accurate thread production.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading applications in steel, stainless steel, hardened steel, and chilled cast iron. The spiral point geometry pushes chips forward ahead of the cut, making it well matched to through-hole work where chip evacuation ahead of the tap is practical. The plug chamfer provides gradual thread engagement, which is typical for production tapping in CNC machining centers, drill presses, and manual tapping applications. It is not intended for blind-hole applications where chip packing is a concern. Right-hand cutting direction requires right-hand rotation for standard installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry advances chips forward, suited for through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHSS-E-PM base material provides improved wear resistance over conventional HSS in abrasive and hard materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer allows gradual thread engagement for smooth cutting entry\u003c\/li\u003e\n  \u003cli\u003e2B class of fit meets standard tolerance requirements for general-purpose inch-thread assemblies\u003c\/li\u003e\n  \u003cli\u003eH3\/H4 thread limit for consistent fit across production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in steel, stainless steel, hardened steel, and chilled cast iron.

Ensure the workpiece is securely fixtured and the tap is properly aligned to the drilled hole before engagement to prevent tap breakage. Use an appropriate cutting fluid or tapping compound recommended for the workpiece material, particularly when threading stainless or hardened steel. For power tapping operations, verify spindle speed and feed rate are set to manufacturer-recommended values for the tap diameter and material before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\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\u003eChamfer Style\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\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Hardened Steel, Chilled Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel-E-PM (Powder Metallurgy)\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: 2.48 inches (2-31\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.827 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.827 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\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\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3992\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: 9039920041660\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51749645582642,"sku":"9039920041660","price":44.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26984840b38552a0ac4391a9bfb5d630_d1c842c4-b2ad-4781-8547-c64803056f7a.jpg?v=1788908735","url":"https:\/\/voomisupply.com\/products\/guhring-9039920041660-spiral-point-tap-8-32-unc-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
