BXA20 – Automotive Part – BXA20


In turning on tapered surface, the competitor’s tool life ends after machining 250pcs/corner due to sudden fracture caused by increased crater wear.- BXA20 with high toughness and crater wear resistance achieves 300pcs/corner, 1.2 times more than the competitor, without a fracture.
