Built from solid carbide with a TiAlN coating applied via PVD process, this insert delivers hardness and heat resistance suited to high-speed threading operations. It cuts right-hand external NPT threads at 8 threads per inch (TPI) and carries the HG330TR manufacturer grade designation. The 3\/8-inch inscribed circle and 0.1614-inch (4.10 mm) thickness conform to the 16ER laydown insert style standard. Machinists and CNC operators working in production environments choose this insert for consistent thread form and tool life on pipe-thread profiles.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external NPT pipe thread applications on materials where a TiAlN-coated solid carbide grade is appropriate, including steel, cast iron, and similar ferrous workpiece materials. It fits 16ER-style toolholders and is well suited to production threading of fittings, nipples, couplings, and other threaded pipe components requiring NPT form. Sold individually per package, with a minimum order quantity of 10 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with TiAlN coating via PVD process for elevated hardness and thermal resistance\u003c\/li\u003e\n\u003cli\u003eExternal NPT thread form, right hand, at 8 TPI\u003c\/li\u003e\n\u003cli\u003e16ER laydown insert style — drop-in fit for compatible 16ER toolholders\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle for stable clamping and precise seating\u003c\/li\u003e\n\u003cli\u003e4.10 mm (0.1614 inch) insert thickness for rigid, repeatable positioning\u003c\/li\u003e\n\u003cli\u003eHG330TR grade designation for consistent performance identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16ER-style laydown threading toolholders configured for external NPT threading operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert seating and clamping should be performed according to the toolholder manufacturer specifications; ensure the insert pocket is clean and free of chips before seating. Power down and lock out the machine spindle before changing inserts. Use appropriate insert removal tools rather than bare hands to avoid injury from sharp cutting edges. Verify thread pitch and form with a calibrated NPT thread gauge after the first pass on a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HG330TR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 4.10 mm (0.1614 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 16ERZ8NPTHG330T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738491715890,"sku":"16ERZ8NPTHG330T","price":270.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2abadfdf815f6ae6e84396753bd969a.jpg?v=1788800223","url":"https:\/\/voomisupply.com\/products\/hertel-16erz8npthg330t-threading-insert-8-tpi-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
