Unlike cutting taps, this tap displaces material rather than removing it, producing stronger threads with no chips to evacuate. It carries a 7\/16-14 UNC thread form, a 2B class of fit, and an H8 thread limit. The modified bottoming chamfer — 2.5 to 3 threads — allows threading close to the bottom of blind holes. The cobalt substrate provides thermal and wear resistance in demanding applications, and the TiCN coating further reduces friction and extends tool life in hard and abrasive materials. Overall length is 3.937 inches (100 mm) and thread length is 0.712 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole and through-hole threading operations in machining centers, CNC lathes, and manual tapping setups. Material application covers aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium — spanning material application codes P, M, N, and H. It fits production environments where chip-free threading and thread strength are priorities, and where coolant-through tooling is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming (chipless) design produces stronger threads and eliminates chip evacuation concerns in blind holes\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2.5 to 3P) allows threading close to hole bottom\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate handles elevated cutting temperatures and hard workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and improves wear resistance across steel, stainless, and high-nickel alloys\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, H8 thread limit, 2B class of fit for standard UNC tolerance requirements\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup on standard tapping equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for 7\/16-14 UNC tapping applications in aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium.

Machine the pilot hole to the appropriate depth and tolerance before tapping. Set spindle speed and feed rate per OSG recommendations for the workpiece material; thread forming generates higher torque than cutting taps, so verify that the tapping head or machine spindle can handle the required torque. Apply a suitable tapping fluid or cutting oil appropriate for the workpiece material to protect the tool and the formed thread.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14 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: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H8\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 to 3P\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: 14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.937 inches (100 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.712 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 1.693 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.242 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.406 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\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: No\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\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: 0.11 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: 1625076148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737314328882,"sku":"1625076148","price":178.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97a1414e31a570fbb064964d71eb3551_951af5bf-5ad8-453b-b9d0-93e43a30e941.jpg?v=1788786980","url":"https:\/\/voomisupply.com\/products\/osg-1625076148-thread-forming-tap-7-16-14-unc-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
