Unlike cutting taps, thread forming taps displace material rather than remove chips, producing stronger threads with superior surface finish. This tap is configured for 2-56 UNC threads at a 3B class of fit with an H2 thread limit, and features a modified bottoming chamfer of 2.5 to 3 threads for threading close to the bottom of blind holes. It is manufactured from cobalt high-speed steel and finished with a TiCN coating, both of which extend tool life in demanding applications. Machinists and tooling specialists in job shops, aerospace, and precision manufacturing environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole and through-hole threading operations across a broad spectrum of materials including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium. The modified bottoming chamfer makes it especially practical when thread depth is critical and full engagement near the hole bottom is required. It is applicable in production machining, maintenance and repair operations, and prototype fabrication wherever 2-56 UNC internal threads are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread forming design cold-works threads for higher strength and no chip evacuation concerns\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 across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer (2.5 to 3 threads) allows threading close to blind hole bottoms\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit and 3B class of fit deliver consistent, close-tolerance thread geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; compatible with blind hole and through-hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for 2-56 UNC internal thread forming in aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium workpieces; material application codes P, M, N, and H.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread forming taps require a properly sized forming tap drill hole, which is larger than the drill size used for cutting taps — consult the applicable forming tap drill chart for 2-56 UNC before drilling. Apply appropriate tapping fluid or cutting oil for the workpiece material; lubrication is critical when forming threads in stainless steel, high-nickel alloys, and titanium. Ensure the tap is driven with a synchronized tapping head or CNC rigid tapping cycle to maintain pitch accuracy and prevent tap breakage. Power down and secure the workpiece in the machine before tool changes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56\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: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 56\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: 2.5 to 3 threads\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.7717 inches (45 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.3846 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.4240 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1410 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1100 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\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: No\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: EXOPRO XPF 16250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 1625002562\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737203048754,"sku":"1625002562","price":100.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1bc3a66e6f1ece49a11903f7aeb0cb9d.jpg?v=1788785547","url":"https:\/\/voomisupply.com\/products\/osg-1625002562-thread-forming-tap-2-56-unc-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
