ない。In particular, when the concave portion formed in the tip is formed on the side portion protruding to the inner edge of the cutting tool body, a large open portion is formed on the inner edge, so that, for example, a concrete structure is cut. Even if the rebar etc. installed inside is cut at the peripheral edge, the cutting chips generated at that time will be discharged without clogging the gap between the chips, and the rotation will stop or fall like the conventional one. There is no need to worry.
