Manufactured from high-speed steel (HSS) with a gold oxide coating, this tap produces 3\/8-24 UNF right-hand threads and features four straight flutes for efficient chip clearance in a wide range of ferrous and non-ferrous materials. The H3 thread limit designation provides a controlled tolerance class suitable for standard UNF thread fits. Licensed machinists, maintenance mechanics, and tool-and-die professionals use this tap for precision threading operations in production and repair environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for use in both manual hand-tapping and low-speed machine tapping applications. The bottoming chamfer — typically 1 to 2 thread lead — allows threading to the bottom of a blind hole, making it the correct choice when a plug or taper tap has already started the thread and full depth is required. It is commonly used in metal fabrication shops, industrial maintenance settings, and general machining work where 3\/8-24 UNF thread specifications are called out on engineering drawings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-24 UNF thread form with right-hand thread direction for standard fastener applications\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer style allows threading to the base of blind holes\u003c\/li\u003e\n  \u003cli\u003eFour straight flutes provide chip clearance and work well in through-hole and short blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction offers durability across a range of common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eGold oxide coating provides light corrosion resistance and reduces friction during cutting\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures a controlled tolerance class for reliable thread fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or working tap for any application requiring 3\/8-24 UNF internal threads; compatible with standard tap handles, T-handle wrenches, and low-speed machine tapping fixtures that accept straight-shank taps of this size class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThreading operations should be performed by a qualified machinist or maintenance professional familiar with proper tap drill sizing for 3\/8-24 UNF threads. Always use appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. For blind holes, use a taper or plug tap first to start the thread before finishing with this bottoming tap. Apply steady, even pressure and back off periodically to break chips and prevent 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: 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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\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: Gold Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: IMPORT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BDNA-20789\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORT-GENERIC","offers":[{"title":"Default Title","offer_id":51698029134130,"sku":"BDNA-20789","price":17.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfaa6094cd2548010fa3e7d3b3220a17.jpg?v=1788356922","url":"https:\/\/voomisupply.com\/products\/import-bdna-20789-straight-flute-tap-3-8-24-unf-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
