Built to the 16 ER insert style, it carries a P25C manufacturer grade with a C5 material grade, making it well-suited for general-purpose threading operations on a range of workpiece materials. The TiN coating is applied via PVD process, providing a hard, wear-resistant surface layer that extends tool life during production threading. With a 3\/8-inch inscribed circle and a thickness of 0.146 inches, this insert fits standard 16 ER toolholders used in CNC and manual turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for machinists and tooling specialists performing external Acme thread forms on lathes and turning centers in manufacturing, job shop, and maintenance machining environments. The Acme thread profile is commonly used in power transmission applications such as lead screws, jacks, and linear actuators. The right-hand orientation suits standard threading passes on conventional setups. This insert is sold individually with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction at P25C grade for reliable tool life in threading operations\u003c\/li\u003e\n  \u003cli\u003eTiN coating via PVD process for improved wear resistance and surface hardness\u003c\/li\u003e\n  \u003cli\u003e12 TPI Acme thread form for power transmission thread cutting applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand external thread orientation for standard lathe threading setups\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle fits standard 16 ER toolholders\u003c\/li\u003e\n  \u003cli\u003e0.146-inch insert thickness for proper seating in compatible insert pockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 16 ER threading toolholders compatible with laydown-style inserts.
