It features a triangular insert shape with a 60-degree included angle and a 0-degree relief angle (clearance code N), making it suited for general-purpose external turning, facing, and profiling operations. The insert is coated with TiCN and TiN layers for improved wear resistance and tool life across a range of workpiece materials. At 1.0195 inches in length with a 5\/8-inch inscribed circle, this insert fits standard TNMG-style toolholders used in production and job-shop environments. Installation is performed by licensed machinists and CNC operators.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in external turning and light-duty interrupted cutting applications across both production and job-shop settings. The MR chip breaker geometry is suited for medium-range cutting conditions where controlled chip formation is required. It is compatible with TNMG-style clamping toolholders that accept a 5\/8-inch inscribed circle insert with a 1\/4-inch hole diameter. The 235 grade designation indicates a CVD-coated carbide substrate optimized for steel and cast iron turning. This insert is sold individually and carries a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiCN and TiN dual-layer coating for enhanced wear resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e60-degree triangular insert shape with 0-degree relief angle for stable cutting geometry\u003c\/li\u003e\n  \u003cli\u003e1\/16-inch corner radius (0.0625 inches) for general-purpose turning and profiling\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch inscribed circle (0.6250 inches) with 1\/4-inch hole diameter for secure clamp and pin holding\u003c\/li\u003e\n  \u003cli\u003eInsert length of 1.0195 inches and thickness of 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003eISO code TNMG 27 06 16-MR 235 for cross-referencing with toolholder catalogs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TNMG-style toolholders that accept a 5\/8-inch inscribed circle insert with clamp and pin holding method.
