高螺旋4刃立铣刀刀具悬伸量请选用所需要的最小尺寸，悬伸量长时容易发生振动，故要降低转数、进给量。

请根据切深量、机床刚性等使用情况，合理调整转数和进给速度。

采用耐热性优良的涂层，可进行高速加工。

广泛用于从普通钢到硬度为HRC50以上的高硬度材料的加工。

※The tool overhang and the minimum size required please choose, overhang long prone to vibration,Therefore, it is necessary to reduce the number of rotation and feed.

※Please according to the cutting depth, the rigidity of the machine tool usage, reasonableadjustment of speed and feed speed .

※The coating is excellent in heat resistance, can be used in high speed machining .

※Most widely used for processing from ordinary steel to hardness of materials withhighhardness above HRC50.
