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 tool is used by hand with a tap wrench for threading operations where full thread depth near the closed end of a bore is required. At 0.31 pounds, it is a compact tool suited for bench work and field tapping tasks.\u003c\/p\u003e\u003cp\u003eThis bottom tap is used in threading applications where a blind hole must be threaded to near-full depth, leaving little clearance at the base. It is a common tool in mechanical assembly, maintenance and repair, fabrication shops, and plumbing or HVAC equipment servicing where large-diameter fastener threads need to be cut or restored by hand. The 1-1\/2 inch by 12 TPI specification is a standard Unified National Fine (UNF)-adjacent coarse-pitch size used in heavy mechanical and piping contexts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottom chamfer profile allows threading to the base of blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction provides hardness and wear resistance for threading steel, iron, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003e1-1\/2 inch diameter with 12 TPI pitch for large-diameter threaded connections\u003c\/li\u003e\n\u003cli\u003eHand tap design used with a standard tap wrench — no machine required\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.31 pounds for easy handling and portability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard hand tool for use in any application requiring a 1-1\/2 inch by 12 TPI bottom tap in HSS.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by hand using a tap wrench; secure the workpiece firmly before beginning to avoid tap breakage. Always back the tap off a partial turn periodically to break chips when threading deeper holes. Ensure the tap is started square to the hole to prevent cross-threading or tool damage. Cutting fluid appropriate to the workpiece material is recommended to extend tap life and improve thread finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 12 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: 0.31 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-15000-12-B-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233801339186,"sku":"HT-15000-12-B-I","price":134.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622652.png?v=1780109352","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-15000-12-b-i-hss-hand-bottom-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
