Made from high speed steel with a bright, uncoated finish, this tap handles demanding threading operations where a fully formed thread must extend close to the bottom of a blind hole. The 4-flute straight flute geometry provides chip clearance and consistent thread form. At 5.75 inches overall length with a 2.56-inch thread length, the C54996 is sized for production and maintenance threading work performed by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for use in manual tapping operations with a tap wrench or machine-assisted hand tapping setups. The bottoming chamfer configuration makes it the finishing tap in a tapping sequence after a taper or plug tap has started the thread. It is appropriate for threading alloy steel, carbon steel, aluminum, and free-machining stainless steel workpieces. Series 1003 construction follows standard UNC thread specifications with a Class 3B fit and H4 thread limit, making it compatible with precision fit fastener applications in general manufacturing, maintenance, and repair environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to within a few threads of the bottom of a blind hole\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides heat resistance and edge retention in tough materials\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute design for stable chip control and thread form consistency\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n  \u003cli\u003eClass 3B fit with H4 thread limit for precision thread tolerance control\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction for standard fastener applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading 1-1\/4-7 UNC internal threads in alloy steel, carbon steel, aluminum, and free-machining stainless steel.

Always use an appropriate cutting fluid matched to the workpiece material to extend tool life and improve thread quality. When tapping blind holes, clear chips frequently to prevent tap breakage. Use this bottoming tap only after a taper or plug tap has already established the thread to its working depth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4-7\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: 7\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\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: 5.75 inches (146.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.021 inches (25.93 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 1.000 inch (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.766 inches (19.46 mm)\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.02 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: C54996\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51711125029170,"sku":"C54996","price":384.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1eba0a9ceed70f41100b6426a563e69.jpg?v=1788474558","url":"https:\/\/voomisupply.com\/products\/cleveland-c54996-hand-tap-1-1-4-7-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
