SUS420J2 52HRC equivalent special small-diameter ball end mill achieves an astonishing lifespan more than twice that of conventional tools.
The MPX coating developed for SUS420J2 hardened steel, along with an optimized tool design, offers more than double the lifespan compared to conventional options!
Ball end mills for finishing high-hardness materials! They provide long tool life and stable machining accuracy.
● Adopted a spiral ball shape to improve the cutting performance of the cutting edge. ● Adopted a cutting edge shape to enhance the chipping resistance of the cutting edge. ● When the outer peripheral edge contacts the workpiece surface, chatter vibrations occur due to increased cutting load, affecting tool life and workpiece surface quality. By adopting a stronger back taper shape, this impact can be mitigated.
