A cutting tool has an insert shaped as a parallelogram that is detachably mounted by a clamp screw4on a tip mounting face of a holder. Concave grooves are formed like parallel stripes on the tip mounting face of the holder, and convex lines are formed on the abdominal face of the insert to be fitted in the concave grooves, so that the insert is clamped by the clamp screw to the holder in a state where the convex lines are fitted in the concave grooves on the tip mounting face.
