Made from high speed steel with a bright, uncoated finish, this right-hand tap features a 4-flute straight-flute geometry that provides chip clearance and thread-cutting stability. The overall length is 4.031 inches, with a 1.09-inch thread length and a 0.542-inch shank diameter. It is rated to a H3 thread limit and produces a Class 2B fit. Machinists, toolmakers, and maintenance techs use this tap for hand-tapping operations on a range of ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThe C54815 is suited for production and maintenance threading tasks in job shops, manufacturing facilities, and field repair environments. It handles blind-hole threading where a bottoming chamfer is required to cut threads close to the bottom of a hole. Compatible material applications include alloy steel, aluminum, carbon steel, and free-machining stainless steel. It belongs to CLEVELAND Series 1003 and is packaged and sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for threading to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e4-flute straight-flute design for chip management and thread accuracy\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluid on a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit with Class 2B fit for standard UNC tolerance requirements\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 11 threads per inch, 11\/16 nominal size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for hand-tapping 11\/16-11 UNC threads in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces, in both blind-hole and through-hole configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is intended for hand-tapping operations using a standard tap wrench or T-handle. Always ensure the hole is drilled to the correct tap-drill diameter for an 11\/16-11 UNC thread before starting. Apply cutting fluid appropriate to the workpiece material to improve thread quality and tap life. Keep the tap aligned perpendicular to the workpiece surface to avoid tap breakage, especially when threading blind holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 11\/16-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.542 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.406 inches\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1003\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C54815\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693644153138,"sku":"C54815","price":93.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ed9ecad631f69ca7f7ebae4f4916ceb_8d8e9058-2965-4a66-bdff-11eba6595c41.jpg?v=1788315422","url":"https:\/\/voomisupply.com\/products\/cleveland-c54815-hand-tap-11-16-11-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
