Utilizing grooving tool GND type chipbreaker series for
excellent chip control.
Low cutting force chipbreakers GF type (neutral) or CF type (handed)
inserts, coupled with a carbide blade, enables stable machining and
prevents chattering even when machining stainless steel.
Achieving stable and longer tool life with the new AC1030U grade.
