Operating on a cold-forming principle, it displaces material rather than removing it, resulting in stronger thread forms with improved surface finish. Built from High-Speed Steel-E-CO (cobalt-enriched HSS) and finished with a TiCN coating, this tap handles demanding materials including steel, stainless steel, cast iron, and non-ferrous metals. It is sized for 8-32 UNC threads with a 2BX class of fit and a modified bottoming chamfer for threading close to the bottom of a blind hole. Machinists and tool-and-die professionals specify this tap for precision threaded assemblies where thread integrity is critical.\u003c\/p\u003e\u003cp\u003eThis tap is suited for both blind hole and through-hole threading applications in production and maintenance environments. The modified bottoming chamfer, featuring 2 to 3 chamfered threads, allows threading to near full depth in blind holes. With a tapping depth of 0.827 inches and a thread length of 0.512 inches, it performs in tight-tolerance work across light manufacturing, metalworking, and precision fabrication. Material application codes P, M, K, and N confirm compatibility across steel, stainless steel, cast iron, and non-ferrous workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming (chipless) design produces stronger threads by cold-working the material\u003c\/li\u003e\n\u003cli\u003eHigh-Speed Steel-E-CO (cobalt) construction for increased heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in abrasive and tough materials\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer (2 to 3P) enables threading close to blind hole floors\u003c\/li\u003e\n\u003cli\u003eH5\/H6 thread limit for tight, controlled fit in 2BX tolerance class applications\u003c\/li\u003e\n\u003cli\u003e4 oil grooves facilitate consistent lubrication delivery during forming\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel, stainless steel, cast iron, and non-ferrous metals as indicated by material application codes P, M, K, and N.

Apply a suitable tapping fluid or cutting oil rated for the workpiece material to the oil grooves before and during tapping. Secure the workpiece firmly and use a tapping head or CNC rigid tapping cycle to maintain axial alignment and avoid tap breakage. Do not use this tap in materials that do not have sufficient ductility to support cold forming.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eClass of Fit\u003c\/strong\u003e: 2BX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\/H6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2 to 3P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eTapping Depth\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\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel-E-CO (Cobalt)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3943\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: 9039430041660\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747603546418,"sku":"9039430041660","price":52.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2337a1572c7a089e9834153af2bc72b3.jpg?v=1788883267","url":"https:\/\/voomisupply.com\/products\/guhring-9039430041660-thread-forming-tap-8-32-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
