With a 1-1\/8 inch diameter and 12 threads per inch (TPI), this tap produces clean, accurate internal threads in applications where minimal thread relief at the bottom of the bore is required. It is used by machinists, millwrights, and maintenance technicians working on ferrous and non-ferrous metals in production and repair environments.\u003c\/p\u003e\u003cp\u003eThis bottom tap is suited for threading blind holes in steel, cast iron, aluminum, and similar materials where a plug or taper tap has already been used to start the thread. It is a standard import-grade tool appropriate for general shop use, maintenance operations, and situations where high-volume production tooling is not required. The 1-1\/8 inch by 12 TPI specification covers a coarse-to-medium pitch range common in industrial fastener and machinery applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHSS construction provides hardness and wear resistance for threading common metals\u003c\/li\u003e\n\u003cli\u003eBottom tap geometry allows threading to within 1-2 threads of the bottom of a blind hole\u003c\/li\u003e\n\u003cli\u003e1-1\/8 inch diameter with 12 TPI for medium-pitch internal thread cutting\u003c\/li\u003e\n\u003cli\u003eHand tap design for use with a tap wrench or T-handle driver\u003c\/li\u003e\n\u003cli\u003eImport-grade tooling suitable for general maintenance and repair use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard hand bottom tap for cutting 1-1\/8 inch by 12 TPI internal threads in blind or through holes across a range of ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by hand using a tap wrench or T-handle; power tapping is not recommended without appropriate torque control. Always ensure the correct drill size for 1-1\/8 inch by 12 TPI threads has been used prior to tapping. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve thread quality. Follow standard shop safety practices, including securing the workpiece before beginning the tapping operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Diameter\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Style\u003c\/strong\u003e: Hand Bottom Tap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.82 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-11250-12-B-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233289339186,"sku":"HT-11250-12-B-I","price":75.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622609.png?v=1780096380","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-11250-12-b-i-hss-hand-bottom-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
