●The Best Spiral Ball Shape for Finishing
Adopted spiral ball shape to improve sharpness of cutting edge.
●NS Original Cutting Edge Shape
Adopted cutting edge shape to improve the chipping resistance of cutting edge.
●Taper Back Shape on Peripheral Cutting Edge
When peripheral cutting edge makes contact with cutting surface, vibration occurs by an increase in cutting resistance and it affects tool life and cutting surface quality.
The influence can be reduced by adoption of the strong back taper shape.
