Taper taps feature a gradual chamfer across the first 8 to 10 threads, allowing the cutting load to be distributed as the tap enters the material. This geometry makes entry easier in through-holes and blind holes where starting alignment is critical. The HSS construction provides adequate hardness and wear resistance for threading mild steel, iron, aluminum, and similar workpiece materials. Plumbers, pipefitters, machinists, and maintenance technicians reach for this style of tap when cutting new threads by hand or with a low-speed tap handle.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for general industrial, mechanical, and trade maintenance applications where 1-3\/8 inch 12 TPI unified or similar coarse-pitch threads are required. Typical scenarios include fabricating threaded holes in metal fixtures, repairing or chasing damaged threads on structural components, and creating threaded ports in custom fabricated assemblies. The hand tap designation means it is intended for manual operation using a standard tap wrench or T-handle, not for machine tapping cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/8 inch diameter, 12 TPI thread form for coarse-pitch threading applications\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer distributes cutting load gradually for easier thread starting\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction resists heat and wear during manual tapping\u003c\/li\u003e\n  \u003cli\u003eHand tap design compatible with standard tap wrenches and T-handles\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.31 pounds for easy handling on the bench or in the field\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style hand tap for use in any application requiring a 1-3\/8 inch 12 TPI taper tap in HSS material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or qualified tradesperson should select the correct tap drill size before starting to ensure proper thread engagement. Secure the workpiece firmly before tapping and use cutting fluid to extend tap life and improve thread quality. Apply steady, even pressure and back the tap off periodically to break chips and prevent binding. Inspect the tap for chipping or wear before each use and replace if the cutting edges are damaged.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Diameter\u003c\/strong\u003e: 1-3\/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\u003eTap Type\u003c\/strong\u003e: Hand Taper\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  \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-13750-12-T-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233931723058,"sku":"HT-13750-12-T-I","price":109.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622653.png?v=1780112474","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-13750-12-t-i-hss-hand-taper-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
