Designed for CNC applications requiring high metal removal rates (MRR) and complex geometry profiling, the 20x20mm shank offers an excellent balance of accessibility and rigidity. Round inserts are the strongest edge geometry available, effectively dissipating heat and mechanical stress over a larger radius. This tool is the ideal solution for roughing and finishing large radius profiles in steel, stainless steel, and cast iron.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003csection style=\"padding: 20px 15px;
