SSPB220 CBN Super Spiral Ball End Mill

[Features]
・ Uses a spiral ball shape that improves the sharpness of the saw teeth.
・ The cutting edge shape used improves the insert resistance of the saw teeth.
・ When the peripheral cutting edge makes contact with the cutting surface, chatter vibration occurs due to an increase in cutting resistance and this affects tool lifespan and cutting surface quality. (This effect can be reduced by using a strong back taper shape.)
・ The standard has expanded to R3 and the processing range has expanded.
・ Helix angle: 20°
