DNX(F) / DNH,DNHSSEC-

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