Designed for use in CNC lathes and manual turning centers, this carbide insert produces UNJ-profile threads with a controlled root radius as specified by the UNJ standard. The MXC grade designation indicates a coated carbide substrate selected for threading performance on a range of ferrous and non-ferrous workpiece materials. At 0.05 pounds, the insert is lightweight and sized for standard ER-style laydown toolholders. It is installed and replaced by machinists and CNC operators as a consumable cutting tool.\u003c\/p\u003e\u003cp\u003eThis insert is suited for threading applications in precision machining environments where UNJ thread forms are required, such as aerospace and defense component manufacturing. The 20 threads-per-inch pitch makes it appropriate for medium-pitch external threading passes on turned parts. It is used in production and job-shop settings where repeatable thread form accuracy and insert interchangeability are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLaydown insert geometry for external thread turning\u003c\/li\u003e\n\u003cli\u003eUNJ thread profile with controlled root radius per UNJ specification\u003c\/li\u003e\n\u003cli\u003e20 threads per inch pitch\u003c\/li\u003e\n\u003cli\u003eMXC coated carbide grade for threading performance\u003c\/li\u003e\n\u003cli\u003eER-style insert form for use in compatible laydown threading toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement threading insert for use in ER-style laydown threading toolholders compatible with the 16ER insert seat size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading inserts are installed and changed by qualified machinists following the toolholder manufacturer torque and clamping procedures. Ensure the machine spindle is stopped and the toolholder is clear of the workpiece before changing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Profile\u003c\/strong\u003e: UNJ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 20 threads per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: Laydown External (ER)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: MXC (coated carbide)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 16ER20UNJMXC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51986356961586,"sku":"16ER20UNJMXC","price":50.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f08834c8f52ff7df9b1224bf71cf2056.jpg?v=1789986079","url":"https:\/\/voomisupply.com\/products\/carmex-16er20unjmxc-laydown-threading-insert-20-unj","provider":"Voomi Supply","version":"1.0","type":"link"}
