Built from high speed steel (HSS) with a bright, uncoated finish, this tap carries a bottoming chamfer — typically 1 to 2 threads — allowing threads to be cut to the very bottom of a blind hole. It is configured for right-hand threading, sized to the UNF thread standard, and meets a 3B class of fit with an H3 thread limit. Overall length is 2.938 inches with a 0.75-inch thread length. Machinists, tool-and-die makers, and maintenance technicians use this tap for precision internal thread work across a range of metallic materials.\u003c\/p\u003e\u003cp\u003eThe C54599 is suited for production and maintenance threading operations on alloy steel, carbon steel, aluminum, and free-machining stainless steel. Its 3-flute straight-flute geometry is appropriate for both blind-hole and through-hole threading scenarios. The bottoming chamfer makes it the final step in a standard tap sequence — following a taper or plug tap — when full threads to the bottom of a hole are required. It fits standard tap wrenches and machine holders sized for a 0.381-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for threading to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across a range of metals\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect thread tolerance\u003c\/li\u003e\n\u003cli\u003e3-flute straight-flute design suitable for blind and through-hole threading\u003c\/li\u003e\n\u003cli\u003eH3 thread limit with 3B class of fit for precise thread tolerance control\u003c\/li\u003e\n\u003cli\u003eRight-hand, UNF 3\/8-24 thread standard — Series 1003\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard tap wrenches and machine tap holders that accept a 0.381-inch shank diameter.

Before tapping, confirm the correct drill size for a 3\/8-24 UNF thread has been used to prepare the hole. Use cutting fluid appropriate for the workpiece material to extend tap life and improve thread finish. In a blind-hole sequence, follow a taper or plug tap with this bottoming tap to achieve full thread depth.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\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: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight\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\u003eOverall Length\u003c\/strong\u003e: 2.938 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches (31.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches (9.68 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches (11.11 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.286 inches (7.26 mm)\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: 1003\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C54599\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51713824522546,"sku":"C54599","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e57c3f3a80a78321dc272235136581c.jpg?v=1788495280","url":"https:\/\/voomisupply.com\/products\/cleveland-c54599-hand-tap-3-8-24-bottoming-hss-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
