Unlike cutting taps, this tool displaces material rather than removing it, producing stronger threads with no chips to clear. It is built from cobalt high-speed steel and finished with a TiCN coating for extended tool life under demanding production conditions. The tap carries a 5\/16-24 UNF thread profile, a 2B class of fit, and an H7 thread limit, making it suitable for precision threaded assemblies. Coolant-through capability supports high-speed tapping operations in CNC machining centers and production tap cycles.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole threading in a wide range of materials including aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, high-nickel alloy, and titanium. The modified bottoming chamfer, with 2 to 2.5 chamfered threads, allows threading close to the bottom of a blind hole. It is used by machinists, tool-and-die makers, and production shops requiring consistent thread quality across high-cycle runs. The OSG EXOPRO XPF-OIL series is engineered for oil-based coolant environments and optimized for the material application codes P, M, K, N, and H.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design produces chip-free, stronger threads by cold-forming rather than cutting\u003c\/li\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\u003eCoolant-through design supports high-speed CNC tapping with oil-based coolant\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer allows threading near the base of blind holes\u003c\/li\u003e\n  \u003cli\u003eH7 thread limit and 2B class of fit meet standard tolerance requirements for precision assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in blind hole threading applications across aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, high-nickel alloy, and titanium workpieces.

Ensure the spindle and tap holder are properly aligned before engaging the workpiece to avoid tap breakage or cross-threading. Use oil-based cutting fluid compatible with the workpiece material and confirm coolant-through flow is active before beginning the cycle. Follow shop safety protocols and machine manufacturer guidelines when handling tooling at operating speeds.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24 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: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H7\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 to 2.5P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5433 inches (90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.555 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.378 inches (35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.238 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.375 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\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16050 EXOPRO XPF-OIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.255 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: 1605056247\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732482720050,"sku":"1605056247","price":141.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/279692742061a87d06b545b80fafa0bf_f925f5d9-c397-4550-aa40-4dce83f36fb1.jpg?v=1788743452","url":"https:\/\/voomisupply.com\/products\/osg-1605056247-thread-forming-tap-5-16-24-unf-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
