A hole is drilled in the center of the middle plate, which is attached to both sides of the middle plate and joined to the outer plate, to form a mounting hole for the middle plate and a fluid passage that penetrates from the mounting hole to the outer edge. A rotary blade body with internal fluid passages can be easily formed.
Utilizing this fluid passage, during cutting, the cooling medium can flow out to the outer periphery of the blade through the fluid passage, lubricating the blade, cooling the blade, and removing chips from the cutting part. This can prevent the blade from deteriorating.
