The P290 - 90° shred milling tools line is based on unique inserts with serrated cutting edges. These tools can also carry regular straight edged inserts for finishing cuts. When the tools are used with the serrated edged P290 ACKT…-FW inserts, very small chips are produced. They are the ideal solution for machining very deep cavities, as the chips can easily be removed from the machining zone, consequently enabling very effective chatter dampening abilities even when positioned at very long overhang positions. The serrations on the cutting edges of the P290 inserts are designed to provide an overlapping effect between all adjacent tool pockets, providing a fully effective cutter configuration.
