It cuts a 2-56 UNC right-hand thread with a 2B class of fit, making it suitable for close-tolerance tapping work. Manufactured from high-speed steel, this tap offers good wear resistance for general-purpose machine and hand tapping. With 2 flutes and an H2 thread limit, it is sized for producing threads in blind holes where full thread depth close to the bottom is required. Overall length is 1.75 inches with a thread length of 0.4375 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for use in light machining, fabrication, and maintenance environments where 2-56 UNC threads are required. Its bottoming chamfer style makes it the correct choice when threading must extend as close as possible to the bottom of a blind hole. Typical applications include machine shops, toolrooms, and field repair operations working with small fastener threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e2-flute straight flute geometry suited for short-chip materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for wear resistance in general-purpose tapping\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for controlled 2B class of fit tolerances\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 2-56 UNC standard\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design  -  compatible with standard cutting fluid application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel.

Before tapping, ensure the correct tap drill size for a 2-56 UNC thread is used and the workpiece is securely fixtured. Apply cutting fluid or tapping compound appropriate for the workpiece material to extend tool life and improve thread quality. Do not force the tap if resistance increases  -  back off to clear chips and prevent breakage.\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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel, High-Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 104\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 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: 1065202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739484258610,"sku":"1065202","price":38.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0171600eee0e2bc6052266bc4fb5c9b.jpg?v=1788815103","url":"https:\/\/voomisupply.com\/products\/osg-1065202-straight-flute-tap-2-56-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
