Constructed from solid carbide and finished with a PVD-applied TiAlN coating, this insert delivers high wear resistance and thermal stability during single-point threading operations on CNC lathes and turning centers. The 16ER insert style seats in a laydown orientation, providing rigid support and repeatable positioning. With a 3\/8 inch (0.3750 inch) inscribed circle and a thickness of 0.1614 inch (4.10 mm), it fits standard 16ER toolholders used in precision machining environments. This insert is used by machinists and CNC operators working with UN-standard threaded components.\u003c\/p\u003e\u003cp\u003eThis insert is suited for right-hand external threading of UN-standard threads at 20 TPI on a variety of workpiece materials. The TiAlN PVD coating makes it effective on steels, stainless steels, and high-temperature alloys where heat and abrasion resistance are critical. It is commonly used in job shops, production machining cells, and toolroom operations where consistent thread quality and insert life are priorities. Sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate for rigidity and wear resistance in threading applications\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating provides thermal stability and extended tool life\u003c\/li\u003e\n\u003cli\u003e20 TPI UN external thread form for standard unified thread production\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for conventional external threading passes\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle, 0.1614 inch thickness fits 16ER laydown toolholders\u003c\/li\u003e\n\u003cli\u003e16ER insert style for laydown seating and secure, repeatable indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 16ER laydown threading toolholders compatible with the 16ER insert style.

Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and insert screw to seat the insert securely without over-tightening the clamping screw. Inspect the toolholder pocket for wear or debris before seating a new insert to ensure proper contact and thread accuracy.\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: HG225TR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\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: 20 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: 0.1614 inch (4.10 mm)\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\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: 16ERZ20UNHG225T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728469983538,"sku":"16ERZ20UNHG225T","price":235.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/182f6bf0332fa296bb72d9ebd23b192d.jpg?v=1788691723","url":"https:\/\/voomisupply.com\/products\/hertel-16erz20unhg225t-threading-insert-20-tpi-3-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
