    • 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 E 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 F 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°.
    • 本发明涉及一种具有由工具柄1和切割区域2-构成的旋转轴线D的铣削工具。 切割区域2具有至少一个擦拭器切割边缘3,其大致垂直于旋转轴线D延伸并且在圆周处合并成主切削刃-4,并且在中心处合并成第二切削刃-5 - 。 副切削刃-5从刮刀切削刃-3向旋转轴线D的方向向后偏移。根据本发明,在切割边缘部分之间的过渡区域中形成有切口6, 刮水器切削刃3和次切削刃5-。 这个凹口6-的点7-,所述点-7--作为在旋转轴线D的方向上的前视图中看到的最后点位于次切削刃-5的最前面的点8之后 - 其中擦拭器切割边缘3与凹口6的相邻部分之间的角度E在90°至175°的范围内,并且刮水器切割边缘-3与该部分 与第二切削刃5邻接的切口6在3°至90°的范围内。 与第二切削刃-5相邻的切口6的该截面与副切削刃-5之间的角度Y在90°-177°的范围内。
