The 16 ER geometry seats in standard ER-style laydown toolholders, providing a stable, repeatable cutting edge for NPT pipe thread forms. With a 3\/8-inch inscribed circle and a thickness of 0.146 inches, this insert is sized for light to medium threading applications on CNC lathes and manual threading setups. Solid carbide construction without coating makes it well-suited for non-ferrous metals, plastics, and other materials where an uncoated edge reduces built-up edge risk. Machinists and toolroom operators are the primary users of this indexable insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is used to produce external NPT taper pipe threads on turned or bar-fed components in production and job-shop environments. The 14 TPI designation targets standard NPT thread sizes commonly found in pipe fittings, hydraulic ports, and fluid-system components. It is appropriate for use on CNC turning centers and manual lathes equipped with ER-style laydown threading toolholders. A minimum order quantity of 10 pieces applies to this part, and the insert is sold individually per package unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003eSolid carbide, uncoated substrate for sharp edge retention on non-ferrous and abrasive materials\u003c\/li\u003e\n \u003cli\u003eRight-hand external NPT thread form at 14 TPI\u003c\/li\u003e\n \u003cli\u003e16 ER laydown geometry for use in standard ER-style laydown threading toolholders\u003c\/li\u003e\n \u003cli\u003e3\/8-inch inscribed circle for consistent seating and indexing\u003c\/li\u003e\n \u003cli\u003e0.146-inch insert thickness for dimensional stability under threading loads\u003c\/li\u003e\n \u003cli\u003eIndexable design allows edge rotation to extend total tool life per insert\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in ER-style laydown threading toolholders accepting 16 ER insert geometry.

Power down and lock out the machine spindle before seating or indexing the insert. Use the correct torque wrench and insert screw specified by the toolholder manufacturer to secure the insert without cracking the carbide. Verify thread form and pitch with a calibrated NPT thread gauge after the first pass before committing to production runs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eThread Form\u003c\/strong\u003e: NPT (National Pipe Taper)\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand External\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 14\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: 16 ER Laydown\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.146 inches\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: CARMEX\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 16ER14NPTC-5P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":68231472054578,"sku":"16ER14NPTC-5P","price":434.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0103875ece23f70f62f6fd056c6cd29b_ccdb3342-88b2-4cd8-8ecb-817939d5ac1d.jpg?v=1793657233","url":"https:\/\/voomisupply.com\/products\/carmex-16er14nptc-5p-laydown-threading-insert-14-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
