It features a multilayer CVD coating of TiCN and Al2O3 over a carbide substrate, providing wear resistance and thermal stability during continuous and interrupted cuts. The diamond-shaped insert carries an 80-degree included angle, a 7-degree relief angle, a 0.0313-inch corner radius, and an MF chip breaker geometry with a chamfered and honed cutting edge. Two usable cutting edges are available per insert. It is held by screw-on mounting in compatible toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel and cast iron workpieces in both production and job-shop environments. The KCP25C grade with its CVD multilayer coating is specifically aimed at P-category steels and K-category cast irons, making it appropriate for general-purpose roughing through semi-finishing passes where consistent chip control and edge life are priorities. The positive rake geometry and MF chip breaker help manage chip flow at moderate to high cutting speeds. Licensed machinists and CNC operators working in metalworking shops are the primary installers and users of this insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer CVD coating: TiN, Al2O3, and TiCN for wear resistance and thermal protection\u003c\/li\u003e\n\u003cli\u003eCCMT diamond-shaped insert with 80-degree included angle and 7-degree relief angle\u003c\/li\u003e\n\u003cli\u003eMF chip breaker with chamfered and honed cutting edge for positive rake cutting action\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eApplicable for turning, facing, and boring operations on steel and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw-on turning insert compatible with CCMT432 (ISO: CCMT120408) toolholder pockets.
