Reduces boundary damage by eliminating changing points from the cutting edge. Reduction of Damage Reduction of Boundary Damage Reduction of Crater Wear Cutting Edge Boundary Wear Comparison Cross Section Crater Wear Comparison Conventional Geometry NEM Type The NEM chipbreaker has no changing points on the The NEM chipbreaker smoothly evacuates chips thanks to cutting edge, so boundary damage is reduced. its large radius rake face design, so crater wear is reduced.
