Taper taps are used to start a thread in a hole, providing gradual cutting action over the first 8 to 10 leading threads to reduce torque and guide the tap squarely into the work. This tap cuts a 5\/16-inch major diameter thread at 18 threads per inch (UNC coarse pitch). It is a hand tap intended for manual tapping operations and light machine tapping. The HSS construction provides good wear resistance and toughness across a range of workpiece materials including mild steel, aluminum, and similar metals.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for maintenance, repair, and fabrication work where 5\/16-18 UNC threaded holes are required. Typical applications include general metalworking, machine shops, HVAC equipment assembly, plumbing fixture fabrication, and field repair work. The taper chamfer makes it the preferred starting tap when threading blind or through holes from scratch. It is commonly used by machinists, millwrights, pipefitters, and maintenance technicians who need to cut or restore internal threads by hand or with a tapping fixture.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form for coarse-pitch internal threading\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer (8-10 leading threads) for easy thread starting and reduced cutting torque\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for durability across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eUSA manufactured for consistent dimensional accuracy and thread form compliance\u003c\/li\u003e\n  \u003cli\u003eHand tap design suitable for manual tapping wrenches and tapping fixtures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 5\/16-18 UNC internal thread.

Use the appropriate cutting fluid or tapping compound for the material being threaded to extend tap life and improve thread finish. Back the tap off a partial turn periodically to break chips and prevent binding. Inspect the tap for wear or damage before each use, as a damaged tap can strip threads or break in the hole.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Hand Taper 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\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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-3125-18-T-D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233888731442,"sku":"HT-3125-18-T-D","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307622795.png?v=1780111302","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ht-3125-18-t-d-5-16-18-hss-taper-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
