Abstract
A rotary cutting tool includes a cutting head having a plurality of insert-receiving pockets for radially mounting a first type of cutting insert in a first cutting region and for tangentially mounting a second type of cutting insert in a second cutting region. The first cutting region has a first length, L, and the second cutting region has a second length, L, that is greater in magnitude than the first length, L. The two types of cutting inserts provides a hybrid cutting insert design in which the first type of cutting inserts provide an increased chip gash volume for effective chip evacuation, and the second type of cutting inserts provide an increased core diameter to minimize deflection of the rotary cutting tool.
