Bottom taps are ground with minimal chamfer on the leading threads, allowing the tap to cut threads as close to the bottom of a blind hole as possible. This makes the HT-10000-8-B-D the correct choice when full threads are required at the base of a stopped bore. Machinists, pipefitters, millwrights, and maintenance technicians reach for bottom taps during repair work and component fabrication where thread depth cannot be compromised.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading 1-inch nominal diameter holes with 8 threads per inch (UNC coarse pitch) in ferrous and non-ferrous metals, plastics, and similar materials. Typical applications include threading bolt holes in structural steel, machinery frames, pipe flanges, and heavy equipment components. The 1-8 UNC thread form is one of the most common coarse-pitch sizes in industrial and mechanical assembly, making this tap a standard item in maintenance and machine-shop toolboxes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottom chamfer geometry allows threading to the base of blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction resists heat and wear during hand-tapping operations\u003c\/li\u003e\n\u003cli\u003e1-8 UNC thread form covers one of the most widely used coarse-pitch sizes in industrial applications\u003c\/li\u003e\n\u003cli\u003eUSA manufactured to hand-tap dimensional standards\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1 unit — available as a single tap\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard hand bottom tap for use in 1-8 UNC tapped holes in ferrous metals, non-ferrous metals, and engineering plastics where a bottom chamfer is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHand bottom taps are installed by machinists and maintenance technicians using a tap wrench sized for the tap square. The workpiece should be secured in a vise or fixture before tapping begins. Apply cutting fluid appropriate to the workpiece material to reduce heat and extend tap life. When tapping blind holes, reverse the tap periodically to break chips and prevent binding that can lead to tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 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: 1.78 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: EAGLE CUTTING TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HT-10000-8-B-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233359921458,"sku":"HT-10000-8-B-D","price":77.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622640.png?v=1780098317","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-10000-8-b-d-1-8-hss-bottom-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
