Manufactured from solid carbide with a PVD-applied TiAlN coating, this insert produces tapered pipe threads at 27 threads per inch (TPI) with a right-hand cutting orientation. The 3\/8 inch (0.3750 inch) inscribed circle and 0.1614 inch thickness conform to the 16ER insert style standard. TiAlN coating provides heat resistance and extended tool life when threading steel, stainless, and cast iron pipe fittings in production environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading operations on pipe fittings, couplings, nipples, and other components requiring NPT-standard tapered threads. It is commonly used in job shops, production machining facilities, and maintenance shops producing or rethreading 27 TPI NPT profiles. Machinists and CNC operators working with ferrous and non-ferrous materials in fluid, gas, and hydraulic piping applications will find this insert appropriate for high-volume and precision threading passes. It is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD TiAlN coating for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003e27 TPI external NPT thread profile for tapered pipe thread applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation, 16ER insert style\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch inscribed circle (0.3750 inch) for compatibility with standard 16ER toolholders\u003c\/li\u003e\n  \u003cli\u003e4.10 mm (0.1614 inch) insert thickness for stable laydown seating\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade HG225TR optimized for threading ferrous and alloy materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for 16ER-style laydown threading insert seats accepting a 3\/8 inch inscribed circle.

Seat the insert firmly in the toolholder pocket and verify torque on the clamping screw per the toolholder manufacturer specification before operation. Confirm thread profile and pitch against a calibrated NPT thread gauge after the first pass. Follow applicable shop safety procedures when handling carbide inserts, as edges are extremely sharp.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: HG225TR\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\u003eThreads Per Inch\u003c\/strong\u003e: 27 TPI\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 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\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\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 16ERZ27NPTHG225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753359049010,"sku":"16ERZ27NPTHG225","price":272.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1fa6a6f1234cb2d09259aab1b76a9a2f.jpg?v=1788935782","url":"https:\/\/voomisupply.com\/products\/hertel-16erz27npthg225-threading-insert-27-tpi-npt-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
