Manufactured from cobalt high-speed steel with a TiCN (Titanium Carbonitride) coating, this tap is built for demanding threading applications where tool life and thread quality are critical. It is configured in the 3-48 UNC thread size with a 3B class of fit and a modified bottoming chamfer of 2.5 to 3 threads, allowing threading close to the bottom of blind holes. Overall length is 1.97 inches (50 mm), with a thread length of 0.39 inches and a tapping depth of 0.42 inches. This tap is part of OSG Series 16250, marketed under the EXOPRO XPF trade name. It is installed by machinists, toolroom technicians, and maintenance trades working on precision threaded assemblies.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for both blind hole and through-hole threading applications in production and maintenance environments. The thread forming method displaces material rather than cutting it, producing stronger threads with better surface finish in ductile materials. Compatible material applications include aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, high-nickel alloy, and titanium. The H2 thread limit provides consistent fit across the 3B tolerance class. This tap is appropriate for light-duty precision work where a 3-48 UNC thread is required in any of these material groups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design produces stronger internal threads by cold-working material rather than cutting\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction provides heat resistance and extended tool life in tough alloys and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and wear, extending tap life in high-nickel alloys and titanium\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2.5 to 3 threads) enables threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit ensures accurate 3B class of fit for precision assemblies\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping equipment and CNC machining centers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading operations in aluminum, cast aluminum, hardened steel, carbon steel, alloy steel, die steel, stainless steel, high-nickel alloy, and titanium workpieces.

Ensure the workpiece is securely fixtured and that adequate tapping fluid or cutting oil appropriate for the workpiece material is applied before tapping. Do not use this tap in brittle materials such as cast iron or hardened workpieces beyond the rated hardness range. Follow all applicable shop safety practices and machine tool operating procedures when setting up tapping operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-48 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: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 2.5 to 3 threads\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 48\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: 1.97 inches (50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.385 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.424 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Name\u003c\/strong\u003e: EXOPRO XPF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.225 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: 1625003482\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749609275698,"sku":"1625003482","price":97.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97a1414e31a570fbb064964d71eb3551_994c9dfc-741e-45aa-9484-c7be4200fb60.jpg?v=1788908292","url":"https:\/\/voomisupply.com\/products\/osg-1625003482-thread-forming-tap-3-48-unc-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
