# Feed rate

The feed rate of the drill must be balanced with the spindle speed. Make a selection from the available combinations of feed rate in the table below to get the desired feed rate. Normally a feed cassette can define two feed rates. By turning it 180 degrees you can change the feed rates, as shown in the figure below.
