SEC- 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!! ■ Series DNX（F）Type DNHS Type DNH Type General Purpose Medium Depth of Cut Small Depth of Cut High Feed High Feed 65° 24° 24° 8mm 5mm 3mm Max.
