It features a bottoming chamfer, which allows threading close to the bottom of a blind hole. Built from high-speed steel (HSS) with an elektraLUBE dry-film coating, this tap reduces friction and galling during the cutting process. It has 2 flutes and a right-hand thread direction, with a thread length of 0.4375 inches and an H2 thread limit for a 2B class of fit. Machinists and toolroom technicians use this tap for fine-thread applications in small-diameter holes.\u003c\/p\u003e\u003cp\u003eThis tap is suited for production and maintenance machining environments where 2-56 UNC internal threads are required. The bottoming chamfer makes it appropriate for blind-hole applications where thread engagement must extend near the floor of the hole. The elektraLUBE coating supports dry or minimal-lubrication tapping in a range of materials. It is typically run in CNC machining centers, drill presses, or tapping machines.\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 for durability in production tapping\u003c\/li\u003e\n\u003cli\u003eelektraLUBE dry-film coating reduces friction and extends tool life\u003c\/li\u003e\n\u003cli\u003eH2 thread limit maintains 2B class of fit tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 2-flute design\u003c\/li\u003e\n\u003cli\u003eThread length of 0.4375 inches for consistent thread engagement depth\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 2-56 UNC internal threads in applications requiring a bottoming tap with a 2B class of fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a tap holder or collet with proper axial alignment to the drilled hole. Always use the correct tap drill size for 2-56 UNC before tapping. Even with the elektraLUBE coating, applying a compatible cutting fluid is recommended for hard or abrasive materials. Inspect the tap for chipping or wear before each use, as fine-pitch taps in small diameters are susceptible to breakage under misalignment or excessive feed force.\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\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 Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: elektraLUBE\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: 103\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: 1205702\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728190341426,"sku":"1205702","price":45.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e75b0fa771815cfb84041701692e26d0.jpg?v=1788689239","url":"https:\/\/voomisupply.com\/products\/osg-1205702-spiral-point-tap-2-56-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
