Part of the OSG EXOPRO XPF-OIL Series 16050, it is configured in 5\/16-18 UNC with a 2B class of fit and a modified bottoming chamfer of 2 to 2.5 threads. The tap is constructed from cobalt high-speed steel and coated with TiCN for extended wear resistance and thermal stability. Overall length is 3.54 inches (90 mm) with a thread length of 0.56 inches and a tapping depth of 1.38 inches. A coolant-through design supports high-production machining environments. Thread limit is H7 with right-hand thread direction.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind-hole threading applications across a wide range of materials including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloy, and titanium. It is applicable to material codes P, M, K, N, and H, covering the majority of ferrous and non-ferrous workpiece categories encountered in production machining, tool and die work, and precision fabrication. The modified bottoming chamfer allows threading close to the bottom of blind holes where standard or plug chamfer taps cannot reach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction provides toughness and heat resistance for demanding materials\u003c\/li\u003e\n  \u003cli\u003eTiCN coating extends tool life and reduces galling in stainless steel and high-nickel alloys\u003c\/li\u003e\n  \u003cli\u003eCoolant-through capability supports high-speed, high-production tapping cycles\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer with 2 to 2.5 thread lead allows threading to near-bottom in blind holes\u003c\/li\u003e\n  \u003cli\u003eH7 thread limit ensures consistent fit tolerance across production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind-hole thread forming in materials including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloy, and titanium. Produces 5\/16-18 UNC 2B class-of-fit threads and is compatible with standard 5\/16-18 tapping fixtures and CNC tapping cycles that support right-hand thread forming taps.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps require a slightly larger pilot hole diameter than cutting taps — consult the OSG Series 16050 recommended drill chart for the correct forming drill size before setup. Power down and lock out all machine spindles before changing or inspecting tooling per standard lockout\/tagout procedures. Apply appropriate tapping fluid or use the coolant-through feature with a compatible cutting fluid rated for the workpiece material. Do not use this tap for thread cutting applications; thread forming taps are not interchangeable with thread cutting taps.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\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: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.54 inches (90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.38 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 Thread Forming\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: 0.065 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: 1605056187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727231353138,"sku":"1605056187","price":155.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/279692742061a87d06b545b80fafa0bf.jpg?v=1788675086","url":"https:\/\/voomisupply.com\/products\/osg-1605056187-thread-forming-tap-5-16-18-unc-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
