When using the smaller side of the cutter diameter or cutting at a large cutting depth or a large cutting width use the lower sides of vc and ft values shown in the table. Dry cutting (including air-blowing) is generally recommended. EPN-type TAC endmills cannot be used for axial-feed cutting such as ramping plungin and drilling.
