Performace

Suppresses winding of chips
Uniform chip curl suppresses chip winding

Low torque
Reduction of torque even for steel-based work materials where cutting resistance increases

Long tool life
Chips are hard to get caught. long life by suppressing blade chipping

for Cast Iron / Cutting of Cast Iron (FC250)

Long tool life

Tool runout was suppressed by the optimization of the twist angle Long tool life with uniform distribution of wear on cutting edges
