Built from micrograin solid carbide and coated with Titanium Nitride (TiN) via a PVD process, this insert delivers consistent thread form and extended tool life in production threading applications. It cuts right-hand internal threads at 8 threads per inch (TPI) and carries a 3\/8 inch inscribed circle (IC) with a thickness of 0.146 inches. Machinists and CNC operators use this insert in threading toolholders configured for laydown-style seating on lathes and multi-axis turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading internal NPT pipe threads in ferrous and non-ferrous materials where a precision thread form and smooth finish are required. The MXC grade micrograin carbide substrate is intended for demanding threading operations where edge integrity and wear resistance are priorities. Typical applications include machining threaded pipe fittings, manifolds, and valve bodies in industrial, plumbing, and fluid-handling component production. This is a single insert sold individually; minimum order quantity is 50 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for superior edge retention in threading operations\u003c\/li\u003e\n  \u003cli\u003eTiN (Titanium Nitride) coating applied via PVD process for improved wear resistance and surface finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal NPT thread form at 8 TPI\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle  -  fits compatible 16IR-style laydown threading toolholders\u003c\/li\u003e\n  \u003cli\u003e0.146 inch insert thickness for precise seating and repeatable positioning\u003c\/li\u003e\n  \u003cli\u003eMXC manufacturer grade targeting consistent performance in production threading environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 16IR-style laydown threading toolholders that accept a 3\/8 inch inscribed circle insert.

Ensure the machine spindle is fully stopped and the toolholder is secured before seating or replacing the insert. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer  -  do not overtighten. Verify insert seating and thread pitch against workpiece specifications before resuming production.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16IR Laydown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin (MXC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch (TPI)\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.146 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 16INRH8NPTMXC\/G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51972365975858,"sku":"16INRH8NPTMXC\/G","price":1390.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61e024fec847dbfd19d9631aba97f272.jpg?v=1789966974","url":"https:\/\/voomisupply.com\/products\/carmex-16inrh8nptmxc-g-threading-insert-8-tpi-npt-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
