Built from cobalt high-speed steel and finished with a TiCN (Titanium Carbonitride) coating, this tap handles demanding threading applications in a wide range of metals. It is configured to the 9\/16-12 UNC thread standard with a 3B class of fit and an H7 thread limit, delivering precise, tolerance-controlled threads. The modified bottoming chamfer — with 2.5 to 3 chamfered threads — allows threading close to the bottom of blind holes. Coolant-through capability supports high-production environments where heat management is critical. Installed by machinists and tooling professionals in production and job-shop settings.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for both blind hole and through-hole threading operations across a broad material range including aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, hardened steel, high-nickel alloy, and titanium. It carries material application codes P, M, K, N, and H, covering the majority of common metal families encountered in industrial and precision machining. The EXOPRO XPF-OIL trade name indicates this tap is optimized for use with oil-based cutting fluids to maximize tool life and thread quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt HSS construction provides heat and wear resistance in tough alloys and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2.5-3P) enables threading close to blind hole floors\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed, high-production tapping cycles\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 9\/16-12 UNC, 3B class of fit, H7 thread limit\u003c\/li\u003e\n  \u003cli\u003eCompatible with both blind hole and through-hole threading applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for thread forming in aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, hardened steel, high-nickel alloy, and titanium workpieces. Suitable for blind hole and through-hole threading in production machining applications under the OSG Series 16050 product family.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps require a properly sized forming tap drill — consult a forming tap drill chart specific to the 9\/16-12 UNC specification, as the required hole diameter differs from a standard cut-tap drill size. Use oil-based cutting fluid as indicated by the EXOPRO XPF-OIL designation to maximize thread quality and tool life. Ensure the workpiece is securely fixtured and the tap is driven with a synchronized tapping head or CNC rigid tapping cycle to maintain accurate thread depth. Engage coolant-through capability when the machine setup supports it, particularly in deep blind hole applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-12 UNC\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: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: 2.5-3P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.3307 inches (110 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.835 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.933 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.429 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.322 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN (Titanium Carbonitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Hardened Steel, Carbon Steel, Alloy Steel, Die Steel, Stainless Steel, High-Nickel Alloy, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16050\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Name\u003c\/strong\u003e: EXOPRO XPF-OIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1605096127\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51755248025906,"sku":"1605096127","price":299.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/279692742061a87d06b545b80fafa0bf_db4783ac-06cc-45b5-9057-86ff064e93a1.jpg?v=1788952638","url":"https:\/\/voomisupply.com\/products\/osg-1605096127-thread-forming-tap-9-16-12-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
