Manufactured from solid carbide with a PVD-applied TiAlN coating, it carries the KC5010 grade designation. The insert follows the LT16ER12UNJ ISO code, features a right-hand cutting orientation, and fits a 3\/8-inch inscribed circle. It is engineered for use on CNC lathes and turning centers where tight thread-form tolerances and tool life consistency are required. Licensed machinists and CNC operators in production and MRO environments install this insert for threading aerospace, industrial, and fluid-system components.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external UNJ threading operations on materials including steel, stainless steel, cast iron, superalloys, and titanium. UNJ thread forms feature a controlled root radius, making them common in aerospace and high-cycle fatigue applications. The ER insert style and size 16 designation are standard in laydown threading toolholders configured for that geometry. The TiAlN PVD coating supports dry or semi-dry cutting conditions and maintains edge integrity across high-temperature cutting passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiAlN coating for extended tool life in demanding materials\u003c\/li\u003e\n\u003cli\u003eRight-hand external UNJ thread form at 12 TPI for aerospace-standard root-radius thread profiles\u003c\/li\u003e\n\u003cli\u003eKC5010 grade optimized for steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eER insert style, size 16, in standard laydown orientation for secure toolholder seating\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle with 0.1430-inch thickness for precise insert pocket fit\u003c\/li\u003e\n\u003cli\u003eHole diameter of 0.1551 inches for standard clamping screw engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement threading insert for laydown-style ER threading toolholders accepting size 16 inserts with a 3\/8-inch inscribed circle and LT16ER-series geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed and replaced by machinists and CNC turning specialists.
