Polished Rake Faces
Especially for milling aluminium alloys and plastics, Horn offers the indexable inserts with polished rake faces on all four edges from stock to counteract the formation of built-up edges. In conjunction with the positive chip breaker geometry, the sharp ground cutting edge produces a soft cut and high surface quality. The special grade is designed for use with the ISO N material group. The inserts can be used in all cutter body variants.
