It cuts a 1\/4-20 UNC right-hand thread to a 3B class of fit with a H3 thread limit, making it well suited for close-tolerance tapping work. The tap is manufactured from high speed steel with a bright, uncoated finish. It features three right-hand flutes with a 52-degree helix angle and a fast flute style that efficiently evacuates chips upward and out of the blind hole. Overall length is 2.5 inches with a thread length of 0.63 inches. Machinists, tool and die makers, and maintenance technicians use this tap by hand or in CNC and manual tapping operations.\u003c\/p\u003e\n\u003cp\u003eThis bottoming tap is intended for blind hole applications where threads must extend as close to the bottom of the hole as possible. It is suited for use in alloy tool steel, carbon steel, and stainless steel. The bottoming chamfer style — typically one to two thread leads — allows threading into holes where a plug or taper tap cannot reach the required thread depth. It fits standard tap wrenches and tapping heads sized for its 0.255-inch shank diameter. This is a single-piece unit sold individually.\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\u003e52-degree helix angle with fast flute style for efficient chip evacuation in blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003e3B class of fit with H3 thread limit for consistent, close-tolerance threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute and right-hand thread — standard orientation for most tapping setups\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with a wide range of cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in alloy tool steel, carbon steel, and stainless steel.

Always drill the correct tap drill size and ensure hole depth exceeds the required thread depth before tapping. Use an appropriate cutting fluid for the workpiece material, particularly when tapping stainless steel. Back the tap out periodically to break and clear chips when tapping by hand.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 52 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Tool Steel, Carbon Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.191 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\u003eSeries\u003c\/strong\u003e: 1093, 1094\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: C58563\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51723163894066,"sku":"C58563","price":40.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1c9c00a1ad0cc65d70fb8a343adf1ba.jpg?v=1788601502","url":"https:\/\/voomisupply.com\/products\/cleveland-c58563-spiral-flute-tap-1-4-20-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
