Advantage of PM series 2-flute ball nose end mill PM-2B PM-2BL PM-2BFP
1)Ultra fine cemented carbide substrate with excellent wear resistance.
2) High-rigidity tool structure reduces virbration.
3) NaNo coating guarantees excellent wear resistance and high temperature stability.
4) Seamless connection of peripheral cutting edge and ball cutting edge is achieved. Optimized center design of ball cutting edge greatly improves surface quality.
