Built from high speed steel with a bright uncoated finish, this 4-flute straight flute tap cuts clean internal threads in both blind holes and through-holes. It carries a Class of Fit 2B designation and Thread Limit H1, making it suitable for standard tolerance threading work. The overall length is 2.5 inches with a thread length of 0.63 inches. This tap is sized for 20 threads per inch on a 1\/4-inch diameter and follows the UNC thread standard. Machinists, tool-and-die makers, and maintenance technicians install this type of tap by hand or with a tap handle.\u003c\/p\u003e\n\u003cp\u003eThe C54445 is intended for threading work in alloy steel, aluminum, carbon steel, and free-machining stainless steel. The bottoming chamfer style leaves threads close to the bottom of a blind hole, making it a frequent choice when full thread depth is required before the hole terminates. It is part of Cleveland Series 1003, which covers standard hand taps for general-purpose threading in production and maintenance environments. Through-hole threading applications are also supported.\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\u003eHigh speed steel construction provides durability across a range of metals\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute geometry suits through-hole and blind hole threading\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluid or tapping compounds\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, UNC standard, Class of Fit 2B\u003c\/li\u003e\n  \u003cli\u003eThread Limit H1 for controlled tolerance threading\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC hand tap for use in conventional tap handles and tapping fixtures that accept straight-shank taps with a 0.255-inch shank diameter and a 5\/16-inch square drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by hand using a tap wrench or T-handle tap holder. Before tapping, ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill size for a 1\/4-20 UNC thread. Apply an appropriate cutting fluid or tapping compound for the material being threaded. A bottoming tap is typically used as the final step in a tap sequence, after a taper or plug tap has started the thread.\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\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: H1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (63.5 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.63 inches (25.4 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches (6.48 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Drive Size\u003c\/strong\u003e: 0.191 inches (4.85 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.3125 inches (7.94 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: 0.06 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: C54445\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51710315528498,"sku":"C54445","price":28.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/345b04a1aed5b9c3f4116678a093b600.jpg?v=1788465495","url":"https:\/\/voomisupply.com\/products\/cleveland-c54445-hand-tap-1-4-20-bottoming-hss-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
