Designated industry standard number CCMT2151LF, it features an 80-degree diamond insert shape, a 0.25-inch inscribed circle, and a 1\/64-inch (0.0156-inch) corner radius. The insert thickness is 3\/32 inch and the insert length is 6.45 mm (0.2539 inches). Manufactured to the KCK20 grade, the PVD coating process delivers excellent wear resistance and edge stability for high-precision turning applications. Cutting edges are honed and the rake is positive, supporting consistent chip control in demanding production environments. Licensed machinists and CNC turning specialists are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel and cast iron workpieces (ISO material codes P and K). It is designed for screw-on insert holding and is appropriate for both residential shop use and industrial production environments. The LF chip breaker is optimized for light to medium finishing cuts, with a maximum depth of cut of 1.25 mm (0.050 inches). It carries a neutral hand designation, making it versatile across a range of tool holders that accept the CCMT 2151 footprint. This insert conforms to ANSI and ISO standards and is applicable across material grades K10 and K25.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCCMT insert style with 80-degree diamond shape and neutral hand orientation\u003c\/li\u003e\n\u003cli\u003eMultilayer PVD AlTiN\/AlCrN coating for wear resistance on steel and cast iron\u003c\/li\u003e\n\u003cli\u003eLF chip breaker geometry engineered for finishing and light roughing passes\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge with positive rake angle of 5 degrees for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method with 2 usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards; compatible with CCMT 2151 toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fit for screw-on toolholders that accept CCMT 2151 insert geometry.
