Coated with TiAlN via a PVD process, this insert delivers wear resistance and thermal stability in demanding threading applications. It carries the KC5010 manufacturer grade and features a chipbreaker (CB) geometry that helps manage chip flow during continuous threading passes. With a 1.50mm pitch and a 3\/8-inch (9.53mm) inscribed circle, it is sized for standard laydown toolholders in the ER16 insert style family. Installation is performed by machinists and CNC tooling technicians on lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is intended for right-hand external threading to ISO thread standards. It is suited for threading operations on ferrous and non-ferrous materials in both production and jobbing environments. The 1.50mm pitch makes it appropriate for metric fastener thread profiles commonly encountered in automotive, aerospace, and general industrial turning work. The CB chipbreaker geometry aids in chip control across a range of materials and cutting conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with TiAlN PVD coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eKC5010 grade optimized for external ISO threading applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard external thread direction\u003c\/li\u003e\n\u003cli\u003e1.50mm pitch for metric ISO thread profiles\u003c\/li\u003e\n\u003cli\u003eCB chipbreaker geometry for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003e3\/8-inch (9.53mm) inscribed circle fits ER16-style laydown toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in ER16-style laydown threading toolholders accepting a 3\/8-inch inscribed circle insert with a 0.1551-inch hole diameter.
