A bottom tap is ground with minimal lead chamfer, allowing threads to be cut to the very bottom of a blind hole. This tool is sized for 8-36 unified fine thread (UNF) applications and is manufactured in the USA. Machinists, maintenance technicians, and tradespeople rely on bottom taps like this one when a thread must extend fully to the base of a shallow or closely toleranced blind bore.\u003c\/p\u003e\u003cp\u003eThe HT-836-B-D is suited for tapping soft to medium-hardness materials including steel, aluminum, brass, and thermoplastics where a full-depth blind-hole thread is required. It is commonly used in HVAC equipment assembly and service, electrical panel fabrication, plumbing fixture work, and general mechanical maintenance. The 8-36 UNF thread designation is standard in precision fastener applications where fine thread engagement and vibration resistance are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottom tap geometry threads blind holes to near full depth\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e8-36 UNF thread form for fine-pitch precision fastener applications\u003c\/li\u003e\n\u003cli\u003eUSA manufactured\u003c\/li\u003e\n\u003cli\u003eStraight flute design compatible with standard tap wrenches and drill press tap holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any application requiring an 8-36 UNF internal thread, particularly in blind holes where a plug or taper tap cannot complete the thread run-out.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eUse the correct 8-36 UNF tap drill size to prepare the hole before tapping. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve thread quality. Advance the tap with steady, even pressure and back off periodically to break chips and prevent binding. Secure the workpiece firmly before tapping and ensure the tap is started square to the hole to avoid tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: Unified Fine (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\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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-836-B-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233985921330,"sku":"HT-836-B-D","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307623133.png?v=1780114071","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-836-b-d-hss-bottom-tap-8-36","provider":"Voomi Supply","version":"1.0","type":"link"}
