It cuts right-hand Acme 3G threads at 12 threads per inch with a 29-degree included angle, matching the standard Acme thread form per ANSI B1.5:1988. The TiAlN coating is applied via PVD process, improving wear resistance and tool life across a wide range of workpiece materials. With a 9.53 mm inscribed circle and 3.6 mm thickness, this insert fits standard 3IR-style toolholders. Machinists and CNC lathe operators working on lead screws, power transmission components, or linear actuator assemblies will find this insert ready for production use.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal Acme thread profiling on CNC lathes and manual thread-turning applications. The VTX grade and universal primary workpiece material rating make it appropriate for steel, stainless steel, cast iron, nonferrous metals, and high-temperature alloys. It is well matched to applications requiring precise 12 TPI Acme thread forms in medium to high production environments, including aerospace, industrial machinery, and general manufacturing settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiAlN coating for extended wear life\u003c\/li\u003e\n\u003cli\u003eCuts right-hand internal Acme 3G threads at 12 TPI with 29-degree included angle\u003c\/li\u003e\n\u003cli\u003e9.53 mm (3\/8 inch) inscribed circle fits standard 3IR-style toolholders\u003c\/li\u003e\n\u003cli\u003eVTX grade rated for universal workpiece materials including steels, stainless, cast iron, nonferrous, and superalloys\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI B1.5:1988 Acme thread standard\u003c\/li\u003e\n\u003cli\u003eManufactured under ISO 9001:2008 quality system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement threading insert for 3IR-style internal threading toolholders accepting a 3\/8-inch inscribed circle laydown insert.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician.
