■ 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.

Good cutting performance and efficient chip evacuation achieved by the vertical, two-corner insert with a circular arc-shaped breaker

Possible to exchange the insert from the back face by drilling a wrench hole on both sides of the screw

The new clamp system with a screw allows easy insert exchange simply by loosening the screw.
