Corner rounding cutters with concave radii from 0.010" to 0.250" (fractional and metric sizes) come in integral shank or shell mill bodies, optimized for performance. Both feature positive geometry for faster cutting and a unique pocket design for excellent repeatability and superior finishes. Integral shank end mill-style bodies, relieved for EM15/EM19 inserts, support aggressive cutting with high repeatability. Shell mill-style bodies, also for EM15/EM19 inserts, provide enhanced cutting action and top-quality surface finishes.
