BXA20 – Automotive Part – BXA20


In facing and external profiling, the competitor’s tool wears quickly, and the surface roughness starts to increase after its CBN substrate is exposed, which ends the tool life.- BXA20 has the thickest PVD coating on the CBN substrate compared to the others, providing good wear resistance, and achieves 1500pcs/corner, while keeping good surface quality.
