Built from cobalt high-speed steel with a TiCN coating, this tap handles demanding applications across a wide range of metals. It features a modified bottoming chamfer with 2 to 2.5 chamfered threads, allowing threading close to the bottom of a blind hole. The overall length is 4.331 inches (110 mm) and the thread length is 0.768 inches. Thread limit is H8, sized for 1\/2-13 UNC with a 2B class of fit and right-hand thread direction. Coolant-through design supports high-speed production environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole threading in both production shop and maintenance machining applications. It performs across a broad material range including aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, hardened steel, high-nickel alloy, and titanium. The OSG EXOPRO XPF-OIL series is engineered for shops running difficult-to-tap materials where chip evacuation is a concern and thread strength is critical. Machinists and tool-and-die professionals working on precision blind-hole components will find this tap well suited to demanding tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design eliminates chip evacuation problems in blind holes\u003c\/li\u003e\n  \u003cli\u003eCobalt HSS construction provides heat and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life across abrasive materials\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2 to 2.5P) for threading near the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eCoolant-through capability supports high-speed CNC tapping cycles\u003c\/li\u003e\n  \u003cli\u003eH8 thread limit for 2B class of fit in 1\/2-13 UNC applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for blind hole threading in aluminum, cast aluminum, carbon steel, alloy steel, die steel, stainless steel, hardened steel, high-nickel alloy, and titanium.

Install in a rigid CNC tapping chuck or tension-compression holder rated for the required torque; avoid hand-tapping in production setups. Ensure coolant-through supply is active when using the internal coolant channel to prevent galling in stainless or high-nickel alloys. Always confirm spindle speed and feed rate match the workpiece material per the manufacturer cutting data before starting a production run.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 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: H8\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: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.331 inches (110 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.768 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: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 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: 0.14 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: 1605012138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732437926194,"sku":"1605012138","price":236.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ce8c103c2f4e9c1038e838098026e59.jpg?v=1788742766","url":"https:\/\/voomisupply.com\/products\/osg-1605012138-thread-forming-tap-1-2-13-unc-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
