Provides extremely good chip management not fluctuated by the material in use. Main chipbreaker that enables good chip control even at low Cross Section of Chipbreaker depths of cut. 1,2 20° Sharp edge with 20° rake angle reduces wear. The grooves on the rake face reduce heat and assist chip flow away from the workpiece.
