■ GG Type/GF Type/CF Type Chipbreaker, New Grade AC1030U
● 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.
■ Performance (Holder)
■ Characteristics
● Holders available in Carbide (SumiGrip) and Steel (SumiGrip Jr.).
● Capable of interrupted machining.
● Can be use for cut-off, grooving and chamfering applications.
