DFE

  • Body

Fig 1

  • Characteristics
  • A brazed type multi flute cutter that is best suited for high feed rate machining
  • Best suited for front face cutting of aluminum alloys and nonferrous metals due to the excellent fracture resistance and cutting performance of DA2200
  • Perfect for small machines. Endmill type small hole cutters
  • Has internal oil delivery type oil hole that handles high speed machining
