Built to the 16ER\/IL style standard, this insert features a 0.031-inch cutting width and a maximum depth of cut of 0.055 inches. A dual-layer TiC and TiN coating improves wear resistance and surface finish consistency across a range of workpiece materials. The right-hand orientation suits conventional turning setups, and a 15-degree rake angle contributes to controlled chip formation. Machining professionals and toolroom technicians are the primary installers of this insert type.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for grooving, profiling, and threading operations on small-diameter workpieces where tight tolerances on groove width and depth are required. The 0.004-inch corner radius and a 3\/8-inch inscribed circle make it appropriate for fine-pitch groove work. It is applicable to both external and internal operations based on the 16ER\/IL insert style designation. Typical use environments include production machining cells, job shops, and tool and die operations working in steel, stainless steel, and similar machinable metals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiC and TiN coating for extended wear life\u003c\/li\u003e\n  \u003cli\u003e0.031-inch cutting width for narrow-groove precision work\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut: 0.055 inches\u003c\/li\u003e\n  \u003cli\u003e15-degree rake angle and 10-degree external relief angle for controlled chip flow\u003c\/li\u003e\n  \u003cli\u003e0.004-inch corner radius supports fine-detail grooving profiles\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation for standard turning setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with toolholders accepting the 16ER\/IL insert style with a 3\/8-inch inscribed circle.
