Bottom taps have minimal chamfer on the leading threads, allowing them to cut usable threads as close to the bottom of a stopped hole as possible. This tap is sized for the 9\/16-18 UNF thread form, combining a medium-diameter shank with fine pitch for applications where thread strength and vibration resistance are priorities. Machinists, pipefitters, and maintenance technicians reach for bottom taps when a plug or taper tap has already started the thread and a complete thread depth is required.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading ferrous and non-ferrous metals in both job-shop and field-maintenance settings. Typical applications include threading blind holes in steel brackets, aluminum housings, and similar structural components. The 9\/16-18 UNF specification is common in hydraulic fittings, automotive assemblies, and general mechanical fabrication where fine-thread engagement is specified. It is appropriate for use in manual tap handles or low-speed machine tapping operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottom-chamfer geometry cuts threads to the floor of blind holes\u003c\/li\u003e\n  \u003cli\u003e9\/16-18 UNF thread form for fine-pitch, high-strength thread engagement\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides heat and wear resistance during cutting\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.32 pounds, easy to handle in confined workspaces\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1, available as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 9\/16-18 UNF bottom tap in high-speed steel, compatible with standard tap handles and tap wrenches sized for the corresponding square drive shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways secure the workpiece before tapping and use a cutting fluid appropriate for the material being threaded to extend tap life and improve thread quality. A plug or taper tap should be used first to start the thread in a blind hole before finishing with this bottom tap. Apply steady, even torque and back off periodically to break chips and prevent tap breakage. Follow applicable shop safety practices and wear appropriate eye protection during all tapping operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-18 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Bottom\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 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: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HT-5625-18-B-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233262666034,"sku":"HT-5625-18-B-D","price":30.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307623056.png?v=1780095621","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-5625-18-b-d-9-16-18-hss-bottom-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
