What is Chip Load? Meaning #1 – How Chip load is used in milling catalogs, and by most machinists. The maximum load that the cutting edge of a specific milling cutter (or indexable insert) can withstand without yielding or having a very short tool-life.. The chip load is specified in mm/tooth or Inch per tooth (IPT) units.
