Definitions

  • the present invention has been made against the background of the above circumstances, and an object of the present invention is to provide a rotary cutting tool capable of supplying a sufficient amount of coolant, suppressing the progress of cutting edge wear, and obtaining cutting efficiency. To provide.
  • FIG. 11 is a diagram corresponding to FIG. 3, showing the shape of the cross section orthogonal to the rotation center line C of the coolant guide concave groove 108 formed in the shank portion 14 in another embodiment of the present invention.
  • the groove bottom 108c curves the rotation center line C as compared with the coolant guide concave groove 18 of FIG. 3 having a linear groove bottom 18c in the direction of the groove width w. It is different in that it is curved in an arc shape at the center and the groove depth d is constant at any position in the direction (circumferential direction) of the groove width w.
  • a groove depth local change position P in which the groove depth changes locally is provided, but it does not necessarily have to be provided.
  • the groove bottom 18c of the coolant guide concave groove 18 may be equidistant from the rotation center line C from the start end 18a to the end end 18b.
