Made from high-speed steel, it produces right-hand internal threads with a 2B class of fit and an H2 thread limit. The bottoming chamfer allows threading close to the bottom of blind holes, making it well suited for tight-tolerance work in small fastener applications. Three flutes provide chip clearance while maintaining rigidity in the small 2-56 thread size. Overall length is 1.75 inches with a thread length of 0.4375 inches.\u003c\/p\u003e\u003cp\u003eThis tap is used in machine shop and production environments where small-diameter 2-56 UNC threads are required. It is appropriate for both manual and CNC tapping operations on materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. The bottoming design is particularly useful in applications where thread depth must reach near the base of a drilled hole, such as electronic enclosures, instrument housings, and precision mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides wear resistance across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eH2 thread limit maintains consistent 2B class of fit tolerances\u003c\/li\u003e\n\u003cli\u003eThree-flute geometry balances chip evacuation with tool strength at the 2-56 diameter\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction compatible with standard tapping toolholders and tap handles\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup in conventional machine environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for tapping 2-56 UNC threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces.

Always ensure the workpiece is properly fixtured and the correct tap drill size for 2-56 UNC is used before tapping. Apply appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. Avoid excessive feed pressure, as small-diameter taps are susceptible to breakage if misaligned or overloaded.\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\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: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 102\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Materials\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel, High-Carbon Steel\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: 1011102\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743951651122,"sku":"1011102","price":34.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/edb5c0a4bd7d7653018f1c27245efd0b.jpg?v=1788851844","url":"https:\/\/voomisupply.com\/products\/osg-1011102-straight-flute-tap-2-56-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
