Abstract
This detachable insert type cutting tool is provided with a cutting insert and a holder which holds the cutting insert. An insert mounting seat on which the cutting insert is mounted and upper and lower jaw sections which pinch the cutting insert are provided in the holder. The insert mounting seat is provided between the lower surface of the upper jaw section and the upper surface of the lower jaw section. Convex curve outer surfaces are formed on one side of the upper and lower jaw sections when viewed from the leading end sides of the upper and lower jaw sections, and concave curve inner surfaces are formed on the other side of the upper and lower jaw sections. In a state where the cutting insert is fixed to the insert mounting seat, the concave curve inner surface of the upper jaw section is disposed at a position retreated further radially outward than an arc surface extending along the concave curve inner surface of the lower jaw section.
