Built from solid carbide and finished with a TiAlN (titanium aluminum nitride) coating applied via PVD process, this insert delivers reliable wear resistance across a wide range of workpiece materials. The 3IR insert style features a right-hand cutting orientation and a 3\/8-inch inscribed circle. The 29-degree included angle matches the Acme thread form standard. Machining professionals and tool-and-die shops install this insert into compatible laydown threading toolholders for precise internal Acme thread production.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal Acme threading operations on lathes and turning centers in both production and job-shop environments. The universal primary workpiece material rating covers a broad spectrum of materials including cast iron, non-ferrous alloys, stainless steel, high-temp alloys, and carbon and alloy steels. It conforms to ANSI B1.5:1988 Acme thread standards, making it appropriate for general mechanical, lead screw, and power transmission thread applications where Acme form geometry is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate for high rigidity and dimensional stability during threading cuts\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating improves heat resistance and extends tool life across varied materials\u003c\/li\u003e\n  \u003cli\u003e6 TPI Acme thread form with 29-degree included angle per ANSI B1.5:1988\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal threading orientation in 3IR laydown style\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle for compatibility with standard 3IR toolholders\u003c\/li\u003e\n  \u003cli\u003eUniversal material grade suitable for steel, stainless, cast iron, non-ferrous, and high-temp alloys\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 3IR-style laydown threading toolholders.
