Bottom taps have a chamfer of 1-2 threads, allowing thread engagement as close to the bottom of a bore as possible. This tap is import-grade tooling suited for machine shops, maintenance facilities, and trade professionals who need a reliable bottom tap for general-purpose threading applications in steel, cast iron, aluminum, and similar materials.\u003c\/p\u003e\u003cp\u003eThis tap is commonly used in metalworking and mechanical maintenance applications where blind-hole threading is required and a plug or taper tap alone cannot complete the full thread depth. Typical users include machinists, pipefitters, millwrights, and industrial maintenance technicians. The 1-1\/4 inch by 8 TPI thread form is frequently encountered in heavy equipment, structural fastening, and industrial fabrication work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottom tap geometry with 1-2 thread chamfer for threading to the base of blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch diameter by 8 TPI thread form for large-fastener applications\u003c\/li\u003e\n\u003cli\u003eHand tap design intended for use with a tap wrench or comparable hand-drive tooling\u003c\/li\u003e\n\u003cli\u003eImport-grade option for cost-effective general maintenance and production use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose bottom hand tap for 1-1\/4 inch by 8 TPI threaded applications in blind-hole metalworking operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eBottom taps are typically the final tap used in a three-tap sequence, following a taper tap and a plug tap to clear and form initial threads. Secure the workpiece firmly before tapping, and use appropriate cutting fluid to extend tool life and improve thread quality. Apply consistent, even torque with a tap wrench and back off periodically to break chips and prevent tap breakage. Follow applicable shop safety standards when performing threading operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 8 TPI\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: 1.8 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-12500-8-B-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233340883250,"sku":"HT-12500-8-B-I","price":79.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622665.png?v=1780097890","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-12500-8-b-i-hss-hand-bottom-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
