PROBLEM TO BE SOLVED: To provide a rotary tool capable of appropriately cutting, with a simple structure, a very thin and slender workpiece and supplying oil mist during the cutting. SOLUTION: On the base end side of a cutting tool 1 with a cutting portion 11 on the front end, there is provided a centrifugal blade 4 that rotates with the cutting tool 1, sucks air from the front end to the base end and discharges the air in the circumferential direction, so that air flowability is generated at the surrounding and ambient surrounding together with rotation of the cutting tool 1, thereby to suck and remove cutting chips discharged during cutting concurrently with the cutting work. Accordingly, continuous removal of cutting chips can be implemented, cutting can be implemented without applying an external force such as air or fluid to a frangible object to be cut, thus appropriately removing cutting chips during formation of a recess chipped shape or the like.
