Part of the Snap-Tap series, it carries a TiAlN\/TiN PVD coating and is manufactured to the CP500 grade, providing wear resistance across a broad range of workpiece materials. The insert features a 60-degree included angle and a right-hand cutting orientation. With a 3\/8 inch inscribed circle and a thickness of 0.1366 inches, this insert seats in standard laydown-style threading toolholders. It is suited for machinists and toolroom technicians working to UN thread standards on turning centers and manual lathes.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external threading operations on materials spanning multiple material groups, including non-ferrous metals, stainless steels, cast irons, carbon steels, and heat-resistant superalloys. The universal primary workpiece material rating makes it appropriate for general-purpose threading applications in job shops, production turning environments, and maintenance machining operations where UN-standard threads are required. The right-hand configuration suits the majority of conventional external threading setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD-applied TiAlN\/TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e28 TPI external UN thread profile with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eCP500 manufacturer grade suited for universal workpiece material compatibility\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle for standard laydown toolholder seating\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0040 inches for precise thread form accuracy\u003c\/li\u003e\n\u003cli\u003eISO-standard insert geometry for consistent, repeatable thread quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling insert for laydown-style external threading toolholders accepting 16ER-style inserts with a 3\/8 inch inscribed circle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified method when securing the insert clamp.
