What is the feed rate of a drill?
The feed rate is the number of millimeters that the tool moves in one minute.
The unit of feed velocity (Vf) of the drill is (mm/min).
The feed rate can be calculated by multiplying the rotation speed listed in the catalog by the feed amount.
The feed amount is the distance of how many millimeters the tool has traveled in one revolution.
Drill feed rate (Vf) = feed amount per revolution (f) × rotation speed (n)
