Bottom taps are ground with minimal chamfer on the leading threads, allowing them to cut threads to the very bottom of a blind hole. This makes the HT-2500-20-B-D the right choice when full thread engagement is required close to the floor of a hole. It is used by hand with a tap wrench and is suited for threading mild steel, aluminum, brass, and similar machinable materials. Plumbers, HVAC technicians, electricians, and general tradespeople reach for bottom taps when finishing blind holes where a taper or plug tap has already started the thread.\u003c\/p\u003e\u003cp\u003eThis tap is designed for threading 1\/4-20 UNC (Unified National Coarse) holes in light fabrication, equipment repair, and field service work. The 1\/4-20 thread size is one of the most common fastener standards in trade and industrial applications, appearing in equipment panels, brackets, enclosures, and mechanical assemblies across HVAC, electrical, and plumbing work. Its compact size and hand-tool operation make it practical for on-site use in tight or awkward locations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottom-chamfer geometry threads to the base of blind holes for full thread depth\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction resists wear and handles moderate-heat cutting conditions\u003c\/li\u003e\n\u003cli\u003e1\/4-20 UNC thread form matches one of the most widely used fastener standards in the trades\u003c\/li\u003e\n\u003cli\u003eUSA manufactured for consistent dimensional accuracy and thread quality\u003c\/li\u003e\n\u003cli\u003eHand-operated design works with standard tap wrenches — no machine required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a hand-operated bottom tap for 1\/4-20 UNC threaded holes in standard tap wrench applications across light fabrication and field repair work.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or skilled tradesperson should use this tap with a properly sized tap wrench to maintain alignment perpendicular to the workpiece. Always use a cutting fluid appropriate for the material being tapped to extend tool life and improve thread quality. Before tapping a blind hole to the bottom, start with a taper or plug tap to establish the thread, then finish with this bottom tap. Clear chips frequently to prevent tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Hand Bottom Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-2500-20-B-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233315291442,"sku":"HT-2500-20-B-D","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622779.png?v=1780097136","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-2500-20-b-d-1-4-20-hss-bottom-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
