Unlike cutting taps, thread forming taps displace material to produce threads, resulting in stronger thread forms with no chips to clear. This tap features a modified bottoming chamfer for threading close to the bottom of a blind hole. The overall length is 2.274 inches with a thread length of 0.261 inches and a shank diameter of 0.141 inches. It is used by machinists and manufacturing tradespeople working on precision threaded assemblies across a wide range of materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for both production and maintenance applications requiring strong, clean internal threads. The cobalt construction with a V-coating provides heat resistance and wear life when working with demanding materials including stainless steel, titanium, high-nickel alloys, hardened steel, alloy steel, die steel, carbon steel, aluminum, and cast aluminum. The modified bottoming chamfer allows threading into shallow blind holes where a standard taper or plug chamfer cannot reach full thread depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design displaces material rather than cutting, producing stronger threads with no chip removal required\u003c\/li\u003e\n  \u003cli\u003eCobalt construction provides elevated heat resistance and hardness for difficult-to-machine materials\u003c\/li\u003e\n  \u003cli\u003eV-coating finish reduces friction and extends tool life in high-wear applications\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer enables threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eCompatible with a broad range of materials including titanium, stainless steel, high-nickel alloys, and aluminum\u003c\/li\u003e\n  \u003cli\u003eOSG Series 16260 construction for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in materials including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloy, and titanium.

Ensure proper alignment between the tap and the pre-drilled hole using a tapping fixture or CNC spindle to avoid tap breakage. The pre-drill hole size for thread forming taps is larger than for cutting taps — consult OSG Series 16260 specifications for the correct forming drill diameter before use. Always secure the workpiece firmly and use appropriate RPM for the material being tapped.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.274 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.261 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 Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16260\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Carbon Steel, Alloy Steel, Die Steel, Hardened Steel, Stainless Steel, High-Nickel Alloy, Titanium\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: 1626000208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746824749362,"sku":"1626000208","price":98.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3299a5522130241ca27ef656891389e6_0894237a-81d8-44c7-8765-5a47c6ec46a3.jpg?v=1788873854","url":"https:\/\/voomisupply.com\/products\/osg-1626000208-thread-forming-tap-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
