Thread forming taps displace material rather than cut it, which results in stronger threads and eliminates chip removal concerns in blind hole applications. This tap features a modified bottoming chamfer with 2 to 2.5 chamfered threads, allowing it to thread close to the bottom of a blind hole. The H2 thread limit holds a 3B class of fit. Built from cobalt high-speed steel with a bright finish and no coolant-through feature, it is suited for production and maintenance tapping in a range of metallic materials. Machinists and tool-and-die technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis tap is designed for blind hole threading operations on machine tools such as drill presses, CNC machining centers, and tapping machines. The 2-56 UNC thread size is common in small fastener applications found in precision instruments, electronics assemblies, and light mechanical components. The cobalt construction and right-hand thread direction make it appropriate for tapping alloy steel, carbon steel, aluminum, die steel, hardened steel, and stainless steel workpieces where heat resistance and edge retention are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread forming design displaces material rather than cutting, producing stronger threads with no chips\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer with 2 to 2.5 chamfered threads for threading close to blind hole bottoms\u003c\/li\u003e\n\u003cli\u003eCobalt high-speed steel construction for heat resistance and extended tool life in tough materials\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for 3B class of fit on 2-56 UNC threads\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, compatible with standard tapping equipment\u003c\/li\u003e\n\u003cli\u003eBright finish with no coolant-through requirement, suitable for use with external cutting fluid application\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole threading of 2-56 UNC right-hand threads in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel.

Secure the workpiece and use a tapping fluid or cutting oil appropriate for the workpiece material before beginning. On CNC equipment, verify spindle speed and feed rate are matched to the tap pitch and material to avoid tap breakage. Always power down or lock out equipment before manually loading or unloading taps.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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\u003eChamfer\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\u003eThreads per Inch\u003c\/strong\u003e: 56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.476 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 Size\u003c\/strong\u003e: 0.11 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 Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HY-PRO NRT 14001\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1400102500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731836961074,"sku":"1400102500","price":38.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9827535bc716ab25b717c00a72bf4620.jpg?v=1788735443","url":"https:\/\/voomisupply.com\/products\/osg-1400102500-thread-forming-tap-2-56-unc-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
