It will make a very noticeable difference if the machine operator does this. Using Multiple Tools for Deep Pockets, Slots, and Cavities. If your machine has a fast tool change and available pockets in the changer, you may be able to perform Deep Pocket Milling more quickly by using multiple tools. The idea is to use more than one stickout.

However, the smaller your end mill, the more fragile it gets, so if you try to cut through material too fast with a 1/16" end mill and you're snapping it off into the workpiece. In most cases the most efficient use of a tool is to cut at around half of the diameter of the tool; with a ¼" tool, have a maximum depth of ⅛".

Slot milling cutters are cutting tools used to machine slots in a workpiece. There are different types of slot milling cutters, selected depending on the shape, size, and width of the slots they are able to produce. Both a face milling cutter and end mills are capable to handle the job. However, each has its advantages and downsides.

The max depth you should use in a slot cut is the diameter of the end mill, so for a 1/4" OD end mill, you can cut 1/4" deep at a time. If you need to go deeper then make multiple passes. The max axial depth of cut, meaning the max amount of the end mill that is touching the work when doing profiling cuts, is 1-1/2 the diameter of the end mill.

Flat-end mills are for profiling, slotting, and side milling. Ball nose end mills are for creating rounded contours. Long neck end mills are usually for pocketing, etc. So, while the number of flutes is important, flute geometry should also be considered. The helix angle of the flutes is also important for machining aluminum.
