Built to the 3ER insert style, it cuts at 14 threads per inch (TPI) to the Unified National thread standard. The insert is manufactured from carbide in the VM7 grade and receives a PVD multi-layer coating for extended wear resistance and thermal stability at the cutting edge. Right-hand cutting geometry makes it compatible with standard external threading toolholders. Machinists and CNC operators install this insert for production threading of external UN fastener profiles in ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading operations in machine shops, production facilities, and job shops running CNC turning equipment. It handles Unified National thread forms at 14 TPI, making it applicable to common fastener and fitting thread profiles. The 3ER style seats into compatible ER-series external threading toolholders. Right-hand orientation means the insert cuts with standard forward-feed threading cycles on most CNC controls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3ER insert style for external UN threading operations\u003c\/li\u003e\n\u003cli\u003e14 TPI Unified National thread standard\u003c\/li\u003e\n\u003cli\u003eVM7 carbide grade with PVD multi-layer coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting geometry for standard CNC threading cycles\u003c\/li\u003e\n\u003cli\u003eExternal thread type  -  designed for OD threading applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 3ER-style external threading toolholders accepting UN thread inserts at 14 TPI.

Power down and lock out the machine spindle before seating or replacing any insert. Use the correct torx or hex key specified by the toolholder manufacturer when securing the insert clamp screw  -  do not overtighten by hand or with impact tools. Verify insert seating and thread pitch against a known gauge or test part before running production.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 3ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN (Unified National)\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 (TPI)\u003c\/strong\u003e: 14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: VM7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD Multi-layer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: VARGUS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51382\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67914493985074,"sku":"51382","price":314.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a650f2d7583b3f979b60c64e93123a63.jpg?v=1791249549","url":"https:\/\/voomisupply.com\/products\/vargus-51382-threading-insert-3er-14-tpi-un-carbide-vm7","provider":"Voomi Supply","version":"1.0","type":"link"}
