MILLING TOOL
The invention relates to a milling tool having a rotation axis D, consisting of a tool shank -1- and a cutting region -2-. The cutting region -2- has at least one wiper cutting edge -3- which runs approximately perpendicularly to the rotation axis D and which merges at the circumference into a main cutting edge -4- and at the centre into a secondary cutting edge -5-. The secondary cutting edge -5- is offset rearwards from the wiper cutting edge -3- in the direction of the rotation axis D. According to the invention, a notch -6- designed as a cutting edge section is formed in the transition zone between wiper cutting edge -3- and secondary cutting edge -5-. The point -7- of this notch -6-, said point -7- being the rearmost point as seen in front view in the direction of the rotation axis D, lies behind the foremost point -8- of the secondary cutting edge -5-, wherein the angle a between the wiper cutting edge -3- and the adjoining section of the notch -6- is within the range of 90° to 175° and the angle ß between the wiper cutting edge -3- and that section of the notch -6- which adjoins the secondary cutting edge -5- is within the range of 3° to 90°. The angle Y between that section of the notch -6- which adjoins the secondary cutting edge -5- and the secondary cutting edge -5- is within the range of 90° - 177°.
