The new line of indexable modular drills combines for the first time a chemical vapor deposition (CVD) coated insert on the outer edge and a physical vapor deposition (PVD) coated insert on the inner edge, enabling high speed and high efficiency processing.
Kyocera's new tools' chipbreakers offer improved chip evacuation and the holder’s thicker centre core provides enhanced rigidity, meaning the new drill is now capable of deep drilling up to 6xD for the first time, in the case of a conventional indexable drill.
The chipbreakers are designed so that four corners (edges) can be used, thereby reducing the customer’s processing costs
The outer edge has a “U-shaped” design to evacuate drilled chips easily and prevent the chips from clogging; and the inner edge has a “spoon-shaped” design to reduce frictional resistance during evacuation of drilled chips, thus enabling excellent evacuation of drilled chips. With this design, it becomes possible to form the flute (groove) into an optimum shape and increase thickness of the holder center core by approximately 33%, compared to competitors’ products. Through the achievement of high rigidity and low resistance, the new model is capable of drilling a deep hole up to 6xD, which has never been possible with a conventional indexable drill.
