More Information
● The helix angle is 38° for the portion near the tip and 20° for the portion near the shank.
● Since the core thickness is thick for the 20° portion, this increases the durability of the tool.
● Using a combination of ultrafine particulate carbide alloy + DLC coating, it has superior wear resistance, which allows for high-speed machining.
● Its durability in aluminum machining is improved with the helix angle combined with a 120° tip angle.
[ ! ]The cutting properties of the blade has been emphasized especially for aluminum and has not undergone honing.
