It carries industry standard designation CNMA433T0820 and is manufactured from silicon nitride ceramic in the KY3500 grade, an uncoated bright-finish formulation engineered for high wear-resistance to moderate wear-resistance and toughness in cast iron applications. The insert features an 80-degree diamond (rhombic) shape, a flat-top chip breaker, a T-Land cutting edge style, and a neutral hand orientation. With a 0.5000-inch inscribed circle, an insert length of 12.90 mm (0.5077 inches), and a corner radius of 3\/64 inches (0.0469 inches), this insert is a precision-geometry component for turning, facing, and boring operations.\u003c\/p\u003e\n\u003cp\u003eThe 1866362 is suited for turning, facing, and boring of cast iron in production machining environments where consistent tool life and dimensional accuracy are required. Its negative rake geometry and negative side clearance are standard for rigid CNMA-style toolholders operating at elevated surface speeds typical of ceramic cutting. The four available cutting edges per insert and flat-top chip breaker geometry support interrupted and continuous cuts on gray, ductile, and hardened cast iron grades. This insert is intended for use by machinists and tooling technicians operating CNC lathes or manual turning centers with appropriate KENLOC-compatible toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon nitride ceramic KY3500 grade delivers high wear-resistance targeting cast iron (K-category) workpiece materials\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (CNMA) with 4 usable cutting edges maximizes insert utilization\u003c\/li\u003e\n  \u003cli\u003eT-Land cutting edge style provides edge reinforcement for interrupted cuts and harder cast iron grades\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker geometry supports stable chip control in turning, facing, and boring applications\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish retains substrate properties without coating delamination risk at ceramic operating speeds\u003c\/li\u003e\n  \u003cli\u003eHeld by clamp and pin method for secure seating in KENLOC toolholders; compliant with ANSI and ISO insert standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production insert for KENLOC-series toolholders accepting CNMA433 geometry inserts per ANSI and ISO standards.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the toolholder pocket locating surfaces and confirm the clamp and pin are properly engaged before resuming cuts.
