The bottom chamfer allows threading to within a few threads of the hole bottom, making it the correct choice when maximum thread depth is required. At 1.8 pounds, it is sized for use with a tap wrench or machine fixture and is suited to threading operations in steel, cast iron, aluminum, and similar materials encountered in industrial and mechanical trade work.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shops, maintenance and repair operations, plumbing rough-in, and mechanical contracting wherever a 1-1\/2 inch-8 UNC thread is required in a blind or through-hole application. The bottom style is selected when a taper or plug tap has already started the thread and full thread depth to the bottom of the bore is needed. It is commonly used by machinists, millwrights, pipefitters, and general mechanical tradespeople working on large-diameter threaded connections, flanges, and industrial equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2 inch diameter, 8 TPI thread form for large-diameter UNC threading applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction provides hardness and wear resistance across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBottom chamfer style threads to within 1-2 threads of a blind hole bottom for maximum thread engagement depth\u003c\/li\u003e\n  \u003cli\u003eHand tap design compatible with standard tap wrenches and manual or light machine tapping fixtures\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 unit supports single-unit procurement for job-specific needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-service hand bottom tap for applications requiring a 1-1\/2 inch-8 UNC thread, compatible with any standard tap wrench or tapping fixture sized for large-diameter hand taps.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBottom taps are typically the final tap used in a three-tap sequence, following a taper tap and a plug tap to bring threads to full depth. Always secure the workpiece and ensure the hole is correctly sized per published tap drill charts before starting. Use appropriate cutting fluid for the workpiece material to extend tap life and reduce the risk of tap breakage. Worn or broken taps in large-diameter bores are difficult to extract, so avoid excessive force and back off frequently to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Style\u003c\/strong\u003e: Hand 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: 1.8 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-15000-8-B-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233305657650,"sku":"HT-15000-8-B-I","price":134.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622690.png?v=1780096879","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-15000-8-b-i-1-1-2-8-hss-bottom-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
