Built from solid carbide with a TiN finish, this insert delivers consistent thread form accuracy on internal Acme profiles. The 3\/8-inch inscribed circle (IC) and 0.146-inch thickness fit standard laydown-style threading toolholders used on CNC lathes and manual turning centers. The TiN coating improves wear resistance and extends tool life in ferrous and non-ferrous materials. This insert is a professional-grade indexable solution for machinists producing Acme-threaded bores in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal Acme thread applications on CNC turning centers and manual lathes. Acme threads are common in power-transmission components such as lead screws, linear actuators, vises, and jacks. The 8 TPI pitch targets medium-to-coarse thread profiles used in industrial and mechanical assemblies. Machinists working in production shops, tool rooms, or maintenance environments will find this insert appropriate for threading bores in steel, cast iron, aluminum, and similar machinable materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003eSolid carbide construction with TiN finish for extended wear resistance\u003c\/li\u003e\n \u003cli\u003eRight-hand internal Acme thread form at 8 TPI\u003c\/li\u003e\n \u003cli\u003e3\/8-inch inscribed circle fits standard laydown threading toolholders\u003c\/li\u003e\n \u003cli\u003e0.146-inch insert thickness for secure, repeatable seating\u003c\/li\u003e\n \u003cli\u003eLaydown-style geometry for rigid clamping and accurate thread profile\u003c\/li\u003e\n \u003cli\u003eIndexable design reduces downtime compared to solid threading tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or production insert for laydown threading toolholders accepting a 3\/8-inch IC threading insert with 0.146-inch thickness and an internal Acme thread form.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Power down and lock out the machine before indexing or replacing the insert. Seat the insert fully in the toolholder pocket and torque the clamping screw to the toolholder manufacturer's specification.
