The bottom chamfer — typically 1 to 2 threads — allows thread cutting extremely close to the base of the hole, making it the preferred tap style when thread depth is limited. At 0.31 pounds, this is a hand-driven tool intended for use with a tap wrench rather than a machine spindle. Machinists, pipefitters, maintenance techs, and general fabricators reach for a bottom tap as the final step in a three-tap sequence or as a standalone tool in shallow blind-hole applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading 1-1\/4 inch-7 UNC (Unified National Coarse) holes in ferrous and non-ferrous materials where a bottom tap is required to achieve full thread engagement near the base of a blind bore. Common applications include repair work, fixture fabrication, and production tapping in shops where hand tapping is standard practice. The 7 TPI pitch is the standard coarse-thread designation for 1-1\/4 inch fastener work across industrial, structural, and mechanical maintenance settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4 inch-7 UNC thread form for standard coarse-pitch applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction provides hardness and wear resistance for threading steel, cast iron, aluminum, and similar materials\u003c\/li\u003e\n  \u003cli\u003eBottom chamfer style allows threading to within 1-2 threads of the base of a blind hole\u003c\/li\u003e\n  \u003cli\u003eHand tap design — intended for tap wrench or hand-held driver use\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.31 pounds for easy single-hand control during tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard hand bottom tap for use in any application requiring 1-1\/4 inch-7 UNC internal threads; compatible with standard 1-1\/4 inch-7 tap wrenches and holders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways secure the workpiece before tapping and use a quality cutting fluid or tapping compound appropriate for the material being threaded. Align the tap perpendicular to the work surface before applying torque to avoid tap breakage or cross-threading. When following a taper or plug tap in a blind hole sequence, clear chips frequently by backing off the tap every few turns. Broken taps in a blind hole are difficult to remove — use proper technique and do not force the tap if resistance increases suddenly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4 inch-7 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: Unified National Coarse (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\u003eWeight\u003c\/strong\u003e: 0.31 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\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-12500-7-B-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233325383986,"sku":"HT-12500-7-B-I","price":88.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622661.png?v=1780097410","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-12500-7-b-i-1-1-4-7-hss-hand-bottom-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
