Running at 12 threads per inch (TPI) with a 29-degree included angle, this insert meets ANSI B1.5:1988 requirements for standard Acme thread profiles. It carries a TiN coating applied via PVD process, which improves surface hardness and extends edge life across a wide range of workpiece materials. The 3ER insert style seats in standard laydown toolholders and is sized with a 3\/8-inch (9.53 mm) inscribed circle and a thickness of 3.6 mm. Installation is right-hand orientation for external threading operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for general-purpose external threading on turning centers in both production and job-shop environments. Its universal material code covers steel, stainless, cast iron, non-ferrous alloys, and heat-resistant superalloys, making it a versatile choice when threading a variety of workpiece materials. It is well matched to applications where Acme thread forms are required, such as lead screws, linear actuators, and power transmission components. Machinists and CNC operators working to ANSI Acme 3G tolerances will find this insert fits standard laydown threading toolholder systems without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD-applied TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e12 TPI Acme 3G thread profile conforming to ANSI B1.5:1988\u003c\/li\u003e\n\u003cli\u003e29-degree included angle matches standard Acme thread geometry\u003c\/li\u003e\n\u003cli\u003e3ER insert style with 3\/8-inch inscribed circle fits common laydown holders\u003c\/li\u003e\n\u003cli\u003eRight-hand external cutting orientation\u003c\/li\u003e\n\u003cli\u003eUniversal workpiece material compatibility including steel, stainless, cast iron, non-ferrous, and superalloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style laydown threading insert for standard 3ER-style toolholders used in external Acme thread turning applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator.
