Our Surfacing Flycutter is designed to accept custom angle tool holders.  This is important for getting the most out of the tool system.  With interchangeable tool holders we can angle CBN, PCD, or Carbide RNGN inserts to Positive or Negative Rake.   This will allow for a ultimate finish for Aluminum with a Negative Rake, where as Cast Iron needs a Positive Rake.   Adapt our Surfacing Flycutter to your CNC Mill, Knee Mill, or Boring Mill with our selection of shanks and adapters.
