The set includes bottoming, plug, and taper chamfer taps, allowing machinists and tooling professionals to start, continue, and finish a threaded hole in sequence. Ground from high speed steel (HSS) with a bright finish, the C54887 delivers reliable thread cutting performance in steel, cast iron, and similar ferrous materials. The 4-flute geometry provides chip control and cutting stability. Overall length is 4.688 inches with a thread length of 2.220 inches, making it suited for standard-depth UNC tapping operations.\u003c\/p\u003e\n\u003cp\u003eThis tap set is used in general machining, maintenance and repair, and production environments where 7\/8-9 UNC threads are required. The three-chamfer combination covers blind holes and through holes alike. The bottoming tap completes threads to the bottom of a blind hole, the plug tap handles most through-hole and mid-depth applications, and the taper tap starts threading in difficult-to-start conditions. This set is appropriate for manual tapping with a tap wrench or use with a tapping head on a drill press or mill. Thread limit is H4, which is a standard tolerance class for general-purpose UNC threading.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-piece set includes bottoming, plug, and taper chamfer taps for complete threading workflow\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread form, right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for cutting ferrous and general-purpose metals\u003c\/li\u003e\n  \u003cli\u003e4-flute design provides chip clearance and cutting stability\u003c\/li\u003e\n  \u003cli\u003eBright finish, no coating — suitable for use with cutting fluid\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit for standard UNC tolerance applications\u003c\/li\u003e\n  \u003cli\u003eOverall length 4.688 inches, thread length 2.220 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 7\/8-9 UNC right-hand internal threads in accordance with Unified National Coarse thread standards.

Secure the workpiece firmly before beginning to prevent movement during tapping. Use an appropriate cutting fluid or tapping compound to extend tool life and improve thread quality. Follow the sequence — taper, then plug, then bottoming — when working blind holes to avoid tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Types\u003c\/strong\u003e: Bottoming, Plug, Taper\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.688 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.220 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePieces Included\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1004\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: C54887\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51711001198898,"sku":"C54887","price":432.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5a77b2f69d53d554e77953dc05fea1b.jpg?v=1788473369","url":"https:\/\/voomisupply.com\/products\/cleveland-c54887-tap-set-7-8-9-unc-4-flute-hss-3-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
