As preferably, the nose angle of arbitrary point of a knife of described milling cutting insert is 55 ~ 60 °.
The angle of any two adjacent edges of described milling cutting insert is 60 °.
The angle α be between the point of a knife bisector of angle of machining position and cutter bar body center line is 93.4 °.
Described knife bar portion is from the front end taper convergent in junction to the knife bar portion with shank section.Like this, the rigidity of this screw cutter is better.
Described air cooling passage is made up of the first air cooling passage X and oblique the second air cooling passage Y being located at knife bar portion running through shank section vertically.
Accompanying drawing explanation
