It carries an 80-degree diamond (rhombic) insert shape with a positive rake angle of 12 degrees and a positive side clearance, making it well suited for stable cutting with controlled chip flow. The inscribed circle measures 0.25 inches, insert length is 0.2539 inches (6.45 mm), and the corner radius is 1\/64 inch (0.0156 inches). Two cutting edges are available per insert. This insert is designed for turning, facing, and boring operations and is installed by machinists and CNC operators on screw-on style toolholders.\u003c\/p\u003e\u003cp\u003eThis insert targets steel and cast iron as primary workpiece materials, with the KCP25 grade offering moderate wear resistance and toughness for both P (steel) and N (aluminum and non-ferrous) material categories. The MP chip breaker geometry is rated for roughing and medium machining operations. It conforms to ANSI insert code CCMT2151 and ISO insert code CCMT060204, making it compatible with standard CCMT screw-on toolholder pockets found in general turning and boring applications across CNC lathes and turning centers in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCP25 grade with multilayer MTCVD TiCN and Al2O3 coating for wear resistance and toughness on steel and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (rhombic) insert shape with positive rake and positive side clearance for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMP chip breaker geometry rated for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method with 2 usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut up to 0.0845 inches\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style for consistent edge integrity\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eConforms to ANSI insert code CCMT2151 and ISO insert code CCMT060204.
