Built from high speed steel with a bright uncoated finish, it is suited for bottoming tap applications where threads must extend close to the bottom of a blind hole. The 2-flute geometry provides adequate chip clearance for a range of common workpiece materials. With an overall length of 1.75 inches and a thread length of 0.44 inches, this tap is sized for small-diameter work requiring precision thread engagement. It is a right-hand tap with a Class 2B fit and an H2 thread limit, meeting standard tolerance requirements for most general-purpose threaded fastener assemblies.\u003c\/p\u003e\u003cp\u003eThis tap is used in machine shops, maintenance environments, and production settings where 2-56 UNC internal threads are required. It is appropriate for both blind hole threading and through-hole threading applications. Compatible workpiece materials include alloy steel, aluminum, carbon steel, and free-machining stainless steel, making it a versatile choice for technicians and machinists working across multiple substrate types. The bottoming chamfer allows thread cutting to within a few threads of the hole bottom, which is critical when working in depth-limited blind holes.\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 across multiple material types\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003e2-flute straight flute design provides chip clearance in light-duty tapping\u003c\/li\u003e\n\u003cli\u003eRight-hand thread, Class 2B fit, H2 thread limit for standard tolerance assemblies\u003c\/li\u003e\n\u003cli\u003eRated for alloy steel, aluminum, carbon steel, and free-machining stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 2-56 UNC internal threads in blind hole and through-hole applications across alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by hand or with a tap wrench and should be used with an appropriate cutting fluid for the workpiece material. Ensure the hole is drilled to the correct tap drill diameter for a 2-56 UNC thread before starting. Back the tap off periodically to break chips and prevent tap breakage, especially in blind holes. Secure the workpiece firmly before tapping to maintain thread alignment.\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\u003eChamfer Type\u003c\/strong\u003e: Bottoming\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: 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\u003eThreads per Inch\u003c\/strong\u003e: 56\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.44 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches (44.45 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches (3.58 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches (2.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: Alloy Steel, Aluminum, Carbon Steel, Free-Machining Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1003\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C54088\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51723999871282,"sku":"C54088","price":35.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97ba1f4aa61c1276d6918dbec3b1d33a.jpg?v=1788611320","url":"https:\/\/voomisupply.com\/products\/cleveland-c54088-hand-tap-2-56-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
