Small radii on GRIP inserts result in increased side forces and side deflection, preventing instability, especially with small depth of cut and feed. The best radius to use is basically determined by the geometry and dimensions of the workpiece. The more securely the workpiece is fastened into the machine tool, the larger the radius may be.
