DNX(F) / DNH,DNHS Type High Efficiency Face Milling Cutters for Cast Iron and Cast Steel
■ Characteristics
●Achieves high efficiency milling with a max. 8 mm depth of cut!
●Employs negative inserts with chipbreakers that have a strong cutting
edge on the double negative type body! Economical, uses 8 corners!
●Supports general to high-efficiency high feed milling with three body types!
Inserts can be shared on all types!


Negative inserts with a rake angle achieve low cutting force and high feed milling!!
