Abstract
A cutting tool is provided for preventing dust intrusion into a guide member effectively as well as cooling a housing, thereby maintaining an excellent operability. A cutting tool has a body housing including an upper housing and a lower housing. In front of a flange portion of the lower housing, right-and-left air outlets are provided. At the front end of the lower housing, right-and-left second guiding ports are provided. Further, between an insulating cover and the lower housing, clearances which allow the outlets and the second guiding ports to communicate with each other are provided. Therefore, when the insulating cover is placed, an air passage is formed in which cooling air discharged from the air outlets moves to the front passing through the clearances, and flows into a space as the junction through the second guiding ports to be discharged to the front.
