Built from solid carbide with an IC250 grade designation, it features a PVD-applied TiCN\/TiN coating for wear resistance and extended tool life when threading cast iron, stainless steel, and steel workpieces. The insert carries a right-hand orientation and an inscribed circle (IC) of 0.375 inches (3\/8 inch), with a thickness of 0.143 inches and a corner radius of 0.016 inches. It belongs to the ISCARTHREAD series and conforms to ISO 13399 standards. This insert is used by machinists and toolroom professionals on CNC lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external UN threading operations in production and job-shop environments. Its IC250 carbide grade with PVD coating targets difficult-to-machine materials including stainless steel and cast iron, as well as general steel. The 16ERM insert style and 8 TPI pitch make it appropriate for coarse-pitch external thread profiles in the UN standard, commonly encountered in industrial fastener production, hydraulic fittings, and general mechanical assemblies requiring unified thread forms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with IC250 grade for hardness and thermal resistance\u003c\/li\u003e\n\u003cli\u003ePVD-applied TiCN\/TiN coating for reduced wear and extended cutting life\u003c\/li\u003e\n\u003cli\u003e8 TPI UN external thread form, right-hand orientation\u003c\/li\u003e\n\u003cli\u003e3\/8 inch (0.375 inches) inscribed circle, 16ERM insert style\u003c\/li\u003e\n\u003cli\u003e0.016 inch corner radius for controlled thread profile accuracy\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standard\u003c\/li\u003e\n\u003cli\u003eM chipbreaker designation for chip control during threading passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in ISCARTHREAD series toolholders and boring bars accepting the 16ERM laydown insert style.

Power down and lock out the machine spindle before seating or removing the insert. Use the correct torx or clamping screw specified for the toolholder to secure the insert; do not over-torque the clamping mechanism. Verify thread pitch, insert orientation, and coolant flow setup before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ERM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\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: IC250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\/TiN, PVD Process\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: 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.143 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.016 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ISCARTHREAD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\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: 5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5920269\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51747239428402,"sku":"5920269","price":143.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a05d0ce05034cf6cea85fcdfa1e6f12e_985f8357-54df-4bf4-b865-25dcc02274b8.jpg?v=1788878004","url":"https:\/\/voomisupply.com\/products\/iscar-5920269-threading-insert-8-tpi-un-solid-carbide-ic250","provider":"Voomi Supply","version":"1.0","type":"link"}
