P系列
四刀刃的圆角型铣刀。φD 1 比 φDc 小,最适合用于深槽加工。刀尖部位有 R 圆弧,可用于带有倾斜角度工件的精加工。
Radius type with 4 flutes. The diameter of the neck portion is thinner than the cutting diameter and it is suitable for deep slotting.
高硬度材质用
Due to the corner R on the cutting edge, it is applicable for finishing of sloped workpiece.
