Machining inches per tooth, abbreviated as IPT, is the amount of material removed by each cutting edge of a tool (such as a milling cutter or a lathe tool) during one revolution of the tool. IPT helps determine the efficiency of material removal and affects factors such as cutting forces, tool life, and surface finish.
