Built from high speed steel (HSS) with a bright, uncoated finish, this 4-flute tap delivers reliable thread formation in both blind-hole and through-hole applications. The taper chamfer — 8 to 10 threads of lead — guides the tap into the hole progressively, reducing the force required to start the cut. With an overall length of 4.688 inches and a thread length of 2.22 inches, the C54884 is sized for typical hand-tapping setups in job shop, maintenance, and production environments. It is threaded to a Class 3B fit at an H4 thread limit, meeting tight-tolerance threading requirements.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for right-hand internal thread cutting in materials including alloy steel, carbon steel, aluminum, and free-machining stainless steel. The taper chamfer makes it appropriate as the starting tap in a hand-tap set sequence or as a standalone tap in through-hole work. The 0.697-inch shank diameter accommodates standard tap wrenches sized for 7\/8 work. The 0.75-inch square drive end provides positive engagement with T-handle and straight-handle tap wrenches. Series 1001 identifies this as part of Cleveland's standard hand-tap line for UNC threads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread form, right-hand, Class 3B fit at H4 thread limit\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer for progressive thread engagement in blind and through-hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for use in alloy steel, carbon steel, aluminum, and free-machining stainless steel\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — inspect and re-coat to application requirements if needed\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for chip clearance in standard materials\u003c\/li\u003e\n  \u003cli\u003e0.75-inch square drive end for secure tap wrench engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in blind-hole and through-hole threading operations requiring a 7\/8-9 UNC right-hand internal thread.

Ensure the workpiece is properly drilled to the correct tap drill diameter for a 7\/8-9 UNC thread before starting. Apply cutting fluid appropriate for the workpiece material to extend tap life and improve thread finish. Back the tap off periodically during cutting to break chips and prevent binding, particularly in 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: 7\/8-9\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\u003eChamfer Type\u003c\/strong\u003e: Taper\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: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\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: 2.22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.697 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Drive Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Drive Size\u003c\/strong\u003e: 0.523 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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1001\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.808 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: C54884\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51697972871474,"sku":"C54884","price":142.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9cbac7e675f07b4f7dc72f63bf24e1e5.jpg?v=1788356391","url":"https:\/\/voomisupply.com\/products\/cleveland-c54884-hand-tap-7-8-9-unc-taper-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
