For Steel / Cutting of Structural Steel (SS400)
Suppresses winding of chips
Uniform chip curl suppresses chip winding
If chips wrap around
Chip removal causes a short stop Cutting edges chipping or breakage due to chip biting
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
Tool runout load and wear state (after 100 holes)
