Made from high speed steel with a bright uncoated finish, it features a 4-flute straight flute geometry and a right-hand thread direction. The bottoming chamfer allows threading to the bottom of blind holes with minimal runout. Overall length is 3.594 inches with a 1 inch thread length. Class of fit is 2B with an H3 thread limit, making it suitable for standard tolerance threading applications across a range of ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machining, fabrication, and maintenance applications where a 9\/16-12 UNC thread is required. It is suited for blind hole and through-hole threading in alloy steel, carbon steel, aluminum, and free-machining stainless steel. The bottoming chamfer style is the final step in a standard three-tap sequence — used after a taper or plug tap has started the thread — making it a standard tool in production shops, tool rooms, and field maintenance operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer cuts threads to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides hardness and wear resistance across common work materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluids across a broad material range\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute design for balanced cutting action and chip clearance\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit and 2B class of fit for standard tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 9\/16-12 UNC designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading alloy steel, carbon steel, aluminum, and free-machining stainless steel.

Always ensure the workpiece is securely clamped and the tap is properly aligned with the pilot hole before applying torque. Apply a suitable cutting fluid for the work material to extend tool life and improve thread finish. When used in a three-tap sequence, use the bottoming tap only after a taper or plug tap has established the thread lead.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-12\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.594 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.429 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.322 inches\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\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: 0.256 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C54761\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698835849522,"sku":"C54761","price":69.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58ffd55eb63f1b304f4f66a4caea6ea0.jpg?v=1788368675","url":"https:\/\/voomisupply.com\/products\/cleveland-c54761-bottoming-hand-tap-9-16-12-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
