In addition to holes from muku on flat machined surfaces, stable machining while dividing chips is possible by the action of insert breaker even in environments where pilot holes have been machined in advance.
In addition, it can be used in "intermittent cutting" environments such as counterboring and plunge machining on inclined and curved surfaces, where the risk of misalignment is inevitably high with general drills.
The processing depth is up to 2D.
