Unlike cutting taps, thread forming taps displace material rather than cut it, resulting in stronger, work-hardened thread walls with no chips to evacuate. This tap is manufactured from High-Speed Steel-E-CO (cobalt-alloyed HSS) and carries a Titanium Nitride (TiN) coating for improved wear resistance and lubricity. The modified bottoming chamfer with 2-3 chamfered threads allows threading close to the bottom of blind holes. Overall length is 4.252 inches with a shank diameter of 0.590 inches. It is sized for a 2BX class of fit and carries thread limits H10 and H11. Machinists and tool-room technicians install this tap in CNC machining centers, drill presses, and tapping heads.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading blind holes and through-holes in steel, stainless steel, cast iron, and non-ferrous metals, corresponding to material application codes P, M, K, and N. The modified bottoming style makes it well-suited for blind-hole threading operations where thread engagement is needed near the bottom of the hole. The 3xD flute-by-diameter ratio and 7 oil grooves support lubrication delivery during the forming process, making it appropriate for both production machining and toolroom work across a range of ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread size 3\/4-16 UNF, right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eHigh-Speed Steel-E-CO (cobalt) construction for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTitanium Nitride (TiN) coating extends tool life and reduces friction\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer with 2-3 chamfered threads for close-to-bottom blind hole threading\u003c\/li\u003e\n  \u003cli\u003e7 oil grooves support lubrication flow during forming\u003c\/li\u003e\n  \u003cli\u003e2BX class of fit, thread limits H10 and H11\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design; suitable for external coolant or cutting fluid application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, stainless steel, cast iron, and non-ferrous metal workpieces.

Always ensure the spindle and workpiece are securely clamped and that the machine is at a complete stop before loading or removing the tap. Use an appropriate tapping fluid or cutting oil rated for the workpiece material to prevent galling, particularly in stainless steel. Verify pilot hole diameter against the manufacturer-recommended forming tap drill chart for 3\/4-16 UNF before threading, as forming taps require a larger pilot hole than cutting taps of the same thread size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: H10, H11\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: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2-3P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.252 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.984 inches (25.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.590 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.442 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel-E-CO (Cobalt HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOil Grooves\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\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: 3941\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 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: 9039410190500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731906167090,"sku":"9039410190500","price":156.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3dca0ca5fed25a8242a6519bd33ce893.jpg?v=1788736388","url":"https:\/\/voomisupply.com\/products\/guhring-9039410190500-thread-forming-tap-3-4-16-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
